hey everyone welcome to introduction to00:00:04
particle tutorial in this course we will00:00:06
create Firebox from scratch starting00:00:08
with basics of particle M we will dive00:00:10
into controlling particle motion and00:00:12
their speed along the way we will00:00:14
explore key attributes and learn how to00:00:16
use them to bust particle effectively00:00:19
once we have created descent particle00:00:20
setup we will focus on look development00:00:23
demonstrating how various attributes can00:00:25
be useful to control color post00:00:26
simulation we will also consolidate the00:00:29
work of 10 nodes into one node00:00:31
showcasing the advantage of using00:00:33
attribute W furthermore we will explore00:00:35
hne 20's Karma xpu setting up and00:00:38
executing renders and even rendering00:00:40
technical a for more control in00:00:42
compositing once rendering is complete00:00:45
we will move to Nuke for final00:00:47
compositing here we will learn how to00:00:48
utilize all aovs to enhance the final00:00:51
Loop check out this new course on00:00:54
particles to learn the basics and more00:00:56
about particle00:00:58
system this is first series of particles00:01:01
so I want to draw attention to learning00:01:04
approach I will suggest to focus on00:01:06
Basics what I mean by Basics is00:01:08
knowledge of essential attributes like00:01:10
ID P scale Alpha Etc and understanding00:01:13
of particle node workflow how to render00:01:15
AO and if I check noes sometimes we have00:01:18
lots of parameters so Master some00:01:20
parameters only most of the effects will00:01:22
be achieved by tweaking few parameters00:01:24
only so don't try to focus on all00:01:26
parameter at once you will be confused00:01:29
won clearly understand where to apply00:01:30
that knowledge but if you are fast00:01:32
learner then it's great but if you think00:01:34
you are not able to understand few00:01:36
things it's totally fine focus on what00:01:38
you understand and most important Master00:01:41
it it will keep you hooked up so in this00:01:43
lesson also I will focus on useful00:01:45
parameter and other parameters we will00:01:47
learn in second series with proper00:01:49
example how to control it and why I'm00:01:51
talking in depth about Basics is Hood00:01:53
need is very open and wholesome package00:01:56
one concept can be applied to another00:01:57
part meaning if you understand part00:01:59
particles workflow and forces really00:02:01
well then you can apply similar concept00:02:03
to RBD also you can apply pop Force same00:02:07
in flip and vum grain also so focus on00:02:09
basic but what about Advanced workflow00:02:12
yes it happen sometimes you come to some00:02:14
complex workflow and it's really00:02:16
important to achieve some result and00:02:17
you're still not on advanced level so00:02:20
don't worry just save somewhere you can00:02:22
easily access it don't try too hard to00:02:24
remember everything if you can do it's00:02:26
great if not then don't worry just save00:02:28
somewhere and remember where it's save00:02:30
and improve and always remember your00:02:32
Creative Vision about FX timing and FX00:02:34
rule of size variation impact and all00:02:37
matters and as we all know our VFX00:02:40
industry is updating too fast AI will be00:02:42
integrated so don't be attached to some00:02:44
system be flexible if something new00:02:47
comes up be ready to learn if you have00:02:49
clear understanding of basic workflow00:02:51
you will be able to apply similar00:02:52
knowledge to run that new system so00:02:54
that's all I wanted to discuss and now00:02:57
let's enter in magical world of00:02:58
particles00:03:02
let's start00:03:06
hne cool close the start page just quick00:03:09
intro this is the viewport we have this00:03:12
is node Network here we can create nodes00:03:15
and here is the00:03:16
parameter and this is shelf great so00:03:19
let's start by Saving this00:03:21
file I'll save it on00:03:23
desktop let's create folder enter to00:03:26
particles one create folder let's name00:03:29
this00:03:30
file particles version00:03:36
one and next I need hot keys so when I00:03:39
press M I need merge node when I press N00:03:42
I need null node as well to create hot00:03:45
Keys we have to use this shelf so create00:03:47
new shelf I want hot keys and here I can00:03:51
just select00:03:53
nodes let's start by merge here we have00:03:56
to specifically select sop merge because00:03:58
we will use it at sop level00:04:00
and next is null this is also soop and00:04:04
object merch let's apply accept let's00:04:08
right click over here edit tool go to00:04:10
last tab hot keys and search for Network00:04:13
pen and click on edit and here we can00:04:16
assign the shortcut just double click00:04:18
over here and press M so it will create00:04:23
that press apply we can see M over here00:04:26
accept so when I press M we hit have00:04:30
merge node and if I using do network if00:04:34
I create M it will create soft Network00:04:38
and it will add that merge node because00:04:40
we have selected sof merge that's00:04:43
why and let's set this as well network00:04:47
but here I cannot use n because it's00:04:50
already assigned here I will use shift00:04:53
n00:04:56
accept and this as well crl00:05:01
M accept00:05:05
accept yep everything is working great00:05:08
let's understand particles Basics00:05:14
Next cool let's understand particles I00:05:17
need00:05:18
geometry so let's take a00:05:23
sphere if I M click over here I have00:05:26
points primitive vertices and polygon00:05:29
and I have position as well let's00:05:31
extract points from this geometry using00:05:39
add Skip points now we can render this00:05:42
as particles with size variation and all00:05:44
but it's a static let's add some moment00:05:46
using00:05:55
Mountain it won't work because we don't00:05:58
have and over here so let's disable00:06:02
this yep it's still static so we have to00:06:05
enable this00:06:09
animation it's not playing in real time00:06:11
so I have to turn this on Real Time00:06:15
problem see it's moving over here but00:06:19
let's understand why it's moving so00:06:21
mountain is adding 3D noise to P so to00:06:26
move particles we have to change its P00:06:28
that's main goal to our direct to follow00:06:30
some curves and add forces also to have00:06:34
a extra control like this over particles00:06:37
we have to use Dynamics operator at the00:06:39
moment we don't have emission control or00:06:41
when we want to kill these particles00:06:44
right but we understood that it's using00:06:47
this00:06:48
position and it's moving the particles I00:06:51
want to explain movement in details so00:06:53
for just quick demo let me use pop00:06:57
Network so I don't want this00:07:01
anymore pop00:07:04
Network and if I connect00:07:07
this yep we have that00:07:10
particles it's similar00:07:16
only right but it has some attributes00:07:19
and which we will study00:07:23
later so how to move this over here do00:07:27
we have any mountain where we can just00:07:29
easily move the position the answer is00:07:31
no here we have to use velocity and00:07:33
forces to move particles I will explain00:07:36
everything later but for now let's just00:07:39
understand this let's play this so as00:07:42
you can see it's not moving right so how00:07:44
do we add velocity so it's very easy we00:07:46
can just go here Point00:07:50
velocity and I want to set velocity so00:07:54
I'll keep it00:07:56
one yep let's check so as you can see00:08:00
it's moving in up Direction now but how00:08:03
this is working is this meter centimeter00:08:05
what is it so for that let's check front00:08:08
view let's go over here front what is00:08:11
one over here one is meter houdy Works00:08:14
in meter so for clarity I will use box00:08:17
over here me use00:08:21
box and this is also 100:08:28
m and I want to make this00:08:32
flat00:08:34
Yep this is also 1 M but for clarity00:08:38
I'll use00:08:39
box so here we have set this one when it00:08:42
will reach over here on first frame or00:08:44
when is it reaching there so if I have00:08:46
mentioned over one it's not reaching on00:08:48
first frame right why because it works00:08:51
based on FPS currently we are using 2400:08:56
FPS as you can see over here so it will00:08:59
reach there on 24 frame00:09:04
exactly and if I change this to00:09:10
48 apply00:09:12
FPS00:09:14
and as you can see it will reach on that00:09:18
frame so always remember when you change00:09:21
velocity or something it works in00:09:23
seconds so if you want to define the00:09:25
speed of an object so you have to00:09:26
extract at meter per second that's how00:09:28
you can figure it out so let's reset00:09:32
everything this as well we understand V00:09:36
but how Force works here is it same like00:09:39
V and let's just check that as well so00:09:43
here I have mentioned one right so I'll00:09:45
just00:09:46
disable I'll just check force and this00:09:50
is just for position only so don't worry00:09:52
about all those things I will cover00:09:54
later so let me type one more here so it00:09:57
should reach here uh on 24 frame but00:10:01
it's not so why it's not reaching on 2400:10:03
frame the reason velocity we have set to00:10:07
one from first frame it will move 1 m/s00:10:10
but when we use pop force it will keep00:10:12
adding that forces so it will start with00:10:15
maybe here we have00:10:18
0.1.5 and all the way it will add that00:10:20
one and it will keep increasing it will00:10:23
go to 2 3 4 but when we use one it will00:10:28
stay constant from first frame so that's00:10:30
how we can easily predict that it will00:10:32
reach over here and best way to check00:10:35
this is let's just quickly check00:10:38
this geometry spreadsheet and I know we00:10:41
have lots of attribute and everything00:10:44
just to check data for now we need to00:10:46
check velocity and we need to check00:10:49
Force here so here we have that Force00:10:54
right but let's focus on velocity here00:10:57
velocity is zero so you can see it's00:11:01
adding it's00:11:03
increasing as I have mentioned right but00:11:06
it will work different when we use only00:11:14
velocity see now we don't have Force but00:11:16
we have velocity first and it won't00:11:19
change at00:11:21
all so that's how it's00:11:27
easy00:11:34
right so it's keep increasing over the00:11:36
time and you can check this Gap as00:11:46
well yep now we understood the00:11:48
difference between velocity and forces00:11:51
that's what happening over here and00:11:53
that's all I wanted to show you now you00:11:54
understood how particles moves and let's00:11:57
understand sourcing and solver also so I00:11:59
want to delete everything00:12:03
now let's take dot00:12:08
Network and connect this over here it's00:12:11
empty right now so earlier we were00:12:13
using pop00:12:16
Network it has everything set up let's00:12:18
start from scratch over here cool I'll00:12:20
talk about this in00:12:23
next let's select this we have some00:12:26
parameters over here one is object merge00:12:29
second is simulation and third is cach00:12:32
so let's start with simulation first so00:12:35
substeps I will talk about later we have00:12:37
this start frame and what is this start00:12:40
frame so if I visualize00:12:42
this can you see this blue line so if I00:12:46
change00:12:48
this 10 and click over here reset00:12:52
sometime it doesn't reset simulation00:12:54
when we change the parameter so we have00:12:56
to manually go over here and click and00:12:59
second option is you can click over here00:13:01
as well just control and click it will00:13:05
reset so as you can see this is start00:13:07
frame time scale and everything I will00:13:10
talk about later and object merge as00:13:12
well yep let's di inside so what we need00:13:15
over here we need solver like pre so00:13:18
let's search solver and we need00:13:22
Pop Let's Start so here we have three00:13:26
inputs one is object second is pre-00:13:30
solve post solve so let's start with00:13:32
object so here if I type00:13:36
object and pop so we have pop object let00:13:40
me connect00:13:41
this yeah now this is ready so all we00:13:45
need is source and for now let's use pop00:13:48
location and where do we connect you can00:13:50
connect anywhere so let's just use this00:13:52
last00:13:57
input yeah so as you can see it started00:14:05
emiting and if I want to change emission00:14:08
shape or something I don't have any00:14:10
option so in most cases you will be00:14:12
using custom shape for emission right so00:14:15
you won't use this so it's better to use00:14:17
this pop00:14:21
Source where we have option to select00:14:24
custom00:14:25
geometry and here we have already custom00:14:28
from geometry and let's see how we can00:14:31
use that so by default it won't read we00:14:33
have to select this geometry source00:14:36
which is first00:14:37
context this00:14:40
input yep it's working now so in00:14:43
previous video we understood how00:14:45
particle moves like position and all but00:14:47
how it moves in real world as well that00:14:49
we also need to understand and here we00:14:52
have this particle right so first it can00:14:56
move on its own right so which is00:14:59
setting a velocity in real world it00:15:01
doesn't happen right the object doesn't00:15:03
move on its own right so to move any00:15:05
object we need extra Force so first here00:15:08
also to move on its own we have to use00:15:10
velocity and in real world second thing00:15:13
is atmosphere so atmosphere can be00:15:16
anything wind or even if we have00:15:18
something on over here if this00:15:22
moves fall an object as well in Dynamics00:15:25
we have to depend on this so we have00:15:29
ground and sphere right so if you want00:15:31
to move this in up direction we won't00:15:34
have any extra push or something we have00:15:35
to depend on velocity or Force you will00:15:39
mostly be using velocity forces and00:15:42
gravity also come under Force so be00:15:44
clear with this things so if you want00:15:46
any custom you know moment or something00:15:49
you have to use velocity and custom00:15:51
forces like that cool now let's talk00:15:54
about this pop00:15:56
Force we have some parameters over here00:15:59
so emission type is set to scatter on00:16:01
two00:16:02
surfaces which you can see it's working00:16:05
and currently it's not moving right so00:16:07
just moment I'll add po00:16:10
Force so it's without moment it will be00:16:13
difficult to explain things yep I will00:16:16
talk about pop Force00:16:18
later but now focus on this thing yep so00:16:23
it's00:16:25
moving and it has some stepping as well00:16:28
which which we will learn how to00:16:30
fix00:16:32
[Music]00:16:34
okay so emission type so first we have00:16:37
all points and what are this all00:16:42
Point yep so it will emit from here and00:16:46
I think I want to change through00:16:53
grid yep now we have more space and easy00:16:57
to understand right right so as you can00:16:59
see it will emit from here and second00:17:02
output is geometry so it can emit00:17:04
geometry as well but we will focus on00:17:07
particles for now and next we have00:17:10
points so what is the difference between00:17:13
points and all points why it's there so00:17:16
all points meaning if I go to Next Step00:17:19
birth if you keep this all points00:17:22
everything is disabled but if you use00:17:25
points we have some parameters enabl00:17:27
over here00:17:29
yep so that's thing I'll and second is00:17:32
scatter on points so it will00:17:37
scatter points on the surface as you can00:17:40
see you know it's random position but if00:17:42
you want equally distributed so you can00:17:45
turn this on as well so you can see it's00:17:48
equally00:17:49
distributed and we have some source00:17:52
group and all what is source group is if00:17:55
you want to select any specific area00:17:57
over here and you can create group of00:17:59
that so I want to select this area and I00:18:02
will just create00:18:04
group00:18:06
yep it's a primitive group right so it00:18:09
will work00:18:12
that so here we have to select primitive00:18:15
and source is00:18:17
group right and similar way we have this00:18:22
emission attribute also it works00:18:23
similarly we just need to add attribute00:18:26
over here so let's just EX example take00:18:29
this00:18:32
and you know by default everything is00:18:35
white only so I have to make sure I have00:18:38
default black00:18:42
value right and here it will carry00:18:48
forward that color as well but I need to00:18:52
use and it will make00:18:54
sure it will emit from White only so00:18:58
those are the00:19:02
things let's delete00:19:05
this next we have scale Point per area00:19:08
to understand this option we have to00:19:10
move to next step and let me just00:19:12
quickly check that so here these four00:19:15
parameters are responsible for particles00:19:17
count and let's start with impulse00:19:20
Activation so this activation means zero00:19:23
it's off one means on if you increase 1000:19:27
also it won't make any change so it00:19:29
works from 0 to one only and second we00:19:32
have impulse so at the moment whatever00:19:34
we were seeing it was using this so if00:19:36
we make constant birth rate zero it00:19:39
won't Adit anything but just for00:19:41
confirmation let's make this zero as00:19:42
well how it works so let me type 100 and00:19:47
I want to know the count to check count00:19:50
let me midle click over here that I have00:19:53
this count so we have 100 points and if00:19:56
I go to next frame00:19:58
we have 200 points so on each frame it00:20:02
will emit 10000:20:03
points and let me turn this off and00:20:08
let's enable this so how this works so00:20:11
this is constant birth rate and let's00:20:14
just check first frame we have five and00:20:19
so we don't have 100 points right so how00:20:21
this works is based on second so let's00:20:24
just check on 24 frames we have 101 so00:20:30
there is will be like minor difference00:20:32
but it will give that 100 points so we00:20:34
understood this impulse count is works00:20:37
on frame and this works on second now00:20:39
let's go back00:20:42
to testing over here what I was talking00:20:46
about this at the moment we have this00:20:49
100 particles over here and if I reduce00:20:53
let me press L to organize this and let00:20:55
me reduce this over here00:20:59
it will still emit 100 but if you want00:21:03
to you know depend on size of source00:21:06
it's bigger I want 100 points if it's00:21:08
smaller I want half of that to do that00:21:11
it will scale by this area so now you00:21:15
can see it's change and if I increase it00:21:18
will increase count00:21:21
accordingly this is how it00:21:24
works so it's depends on area00:21:29
right so what happens sometimes let me00:21:31
explain so we have like two Source in00:21:34
this SC and here it will emit 100 points00:21:38
and 100 points right but in this area it00:21:40
doesn't make having 100 points right00:21:43
here it mix it will fill that Gap but it00:21:46
will over scatter over here to control00:21:48
that you know if source is smaller I00:21:51
want lesser points in this area so you00:21:53
can just use this parameter let's close00:21:56
I don't want to use this and00:21:58
let's reset here as well 5x00:22:08
5 I want to reset everything and here we00:22:11
have this Max Control and next is just00:22:13
Bond so it creates this just Bond group00:22:18
let me just use00:22:21
Bond and here also we can just middle00:22:23
click and check that group so here we00:22:26
have option one show Point attributes00:22:28
and seconds shows Point group as well so00:22:31
now we have Bond group and on first00:22:34
frame we have this 200 so let me just00:22:37
check this 100 frames00:22:39
only right so if I reset this we have00:22:41
this 100 maybe on 10 frame we should00:22:44
have 1,000 over here let's just check00:22:47
count is 1,000 but just B same 100 so00:22:51
how this works is whatever emits over00:22:53
here it will just add that into group so00:22:56
whever you want to use it maybe on just00:22:58
one group you want to add some force and00:23:00
after that it won't add any force on00:23:02
first frame only it will add some force00:23:05
and next is00:23:12
SE and most important is life how this00:23:15
works so this also works based on00:23:18
second if I type one so everything will00:23:22
be deleted on00:23:25
24 and it's not visible over here so I00:23:28
have to animate this thing I will amate00:23:31
on first frame and after that00:23:34
zero and let's just increase count00:23:41
also yep so on00:23:45
24 or 25 it's just one frame offset00:23:50
only if we have started from zero it00:23:54
will accurately delete on this00:23:56
Frame00:23:58
yep it's working that way so if you want00:24:01
any variation in between that maybe by00:24:03
half so at the moment one is this thing00:24:06
right if you type life variation 5 means00:24:09
it will use this range to delete that00:24:12
gradually sorry it's 05 and it will00:24:15
delete everything at once so that00:24:17
doesn't look cool so if I check and see00:24:22
started deleting but it's not visible00:24:24
over here let me just middle click can00:24:27
you see the count is00:24:28
reducing here we have 1,000 points and00:24:33
it's reduced and it will reduce00:24:36
gradually and we don't have that the00:24:39
range I have described so that's how it00:24:47
works and we have Jitter birth time00:24:51
also so here we have some option Point00:24:54
negative so this is useful when we have00:24:57
some velocity over here let me use Point00:25:00
velocity to set some velocity over here00:25:03
and00:25:07
set yeah so to just give some Jer over00:25:11
here you can just use00:25:13
negative and positive value as well and00:25:16
we have this thing Point velocity as00:25:20
well so where you want to use this to00:25:23
fix that stepping you know earlier we00:25:25
were getting some stepping00:25:30
now it will fix00:25:35
that and just go to00:25:40
front now we have that right so let's00:25:44
just increase this even00:25:48
more can you00:25:50
see it fixing00:25:54
that we can still see some00:25:59
but if I disable this we don't have and00:26:02
if I keep this null we have00:26:06
some positive negative so positive means00:26:09
it00:26:11
will use this in positive direction00:26:14
negative means it will use backward so00:26:17
both works and here also we oops I have00:26:20
to use negative and back and it's Point00:26:26
yep00:26:32
let's just reset00:26:34
everything and I want to keep null and I00:26:37
will get some that's00:26:42
fine cool next we have attributes and00:26:46
again I will00:26:48
need00:26:49
that so here we have inherit attributes00:26:54
right so if you have any extra attribute00:26:56
over here maybe let's add00:27:01
color00:27:04
green you know by default it will00:27:07
inherit that attribute carry forward00:27:09
anything over here so if I keep it00:27:11
zero means it won't carry for anything00:27:14
but I want00:27:16
velocity so I can just use that and here00:27:20
I want to use everything but not color00:27:23
so I can just use this so it will bypass00:27:26
that00:27:29
so now we don't have that color cool00:27:31
that's is so here also we have inherit00:27:34
velocity it this works as a00:27:39
scale right so you can just reduce00:27:42
this and I have other options as well I00:27:45
can add to inherit velocity and I have00:27:48
set initial velocity as well so here00:27:51
I'll just keep whatever I have set over00:27:53
here and I can add my extra velocity as00:27:56
well so I can just type five over here00:27:58
it will move in this00:28:01
direction right and what is this00:28:04
variance over00:28:05
here so for now let me just keep00:28:08
everything zero to explain these things00:28:11
so variance is like this thing so it00:28:14
will just go random Direction and where00:28:17
it's00:28:18
useful it's very00:28:22
useful earlier we were getting some00:28:25
stepping issue right and there are lots00:28:27
of to fix00:28:31
it so variance if I add point5 Varian00:28:37
and let's just reset stay on this Frame00:28:39
let's reset so as I have mentioned it00:28:42
doesn't work right so this is not00:28:44
working but if I go outside it works00:28:48
somehow it doesn't reset so you have to00:28:50
just go this frames to00:28:53
check yep now you have noticed that it's00:28:57
zero00:28:58
again after reset it won't work I have00:29:01
to go these things yep so if I any add00:29:06
it will00:29:07
reset and it will just mix because we00:29:11
have random variance so it won't have00:29:13
equal00:29:15
distribution right this looks cool even00:29:20
it will fix this as well so earlier we00:29:23
were getting lots of stepping issue over00:29:25
here but now it's fixed because of00:29:32
these see if I don't00:29:37
use we have00:29:39
stabing yeah so let's keep this00:29:42
everything default to set this to00:29:44
default you can just control mid click00:29:46
over here M click over here as well now00:29:49
I don't want to use any color yep now we00:29:52
have one more parameter add ID and ID is00:29:55
very very useful most important00:29:57
parameter in particles is ID so you00:30:00
cannot miss it so let's just understand00:30:03
and I want to M it on just first frame00:30:09
only yep so we have this thing and let00:30:13
me just kill this00:30:16
particle I need some00:30:19
range00:30:23
y let's reduce00:30:26
this00:30:30
yep so I have some icons over here so00:30:33
for now let me turn on this display00:30:36
Point00:30:37
numbers and we have this point numbers00:30:40
let's keep 10 points00:30:44
only to understand so as you can see we00:30:49
have 0 to 9 over here let's just move00:30:54
can you see it's shifting right00:30:59
and why it's shifting because it's00:31:02
changing its Point count and ID is00:31:05
something totally different so ID00:31:07
remembers this is point number three00:31:09
it's like a name you know if 10 people00:31:12
they known by their names right so if00:31:14
XYZ or something and to explain you this00:31:17
I have to show you some quick example so00:31:19
let me just use random and I will talk00:31:22
about this P scale and everything00:31:25
later but for now just one00:31:35
example right so as you can see now we00:31:38
have this count and hopes what do you00:31:43
think how it will look when we enter00:31:45
this this is not right right and how do00:31:48
we fix we need ID so let's create ID so00:31:52
I think we can just use Point00:31:55
triangle I at ID equals00:32:01
ptin will this fix it if I turn this on00:32:07
ID no it won't fix so this is wrong way00:32:12
why I'm showing you this you know it's00:32:13
misunderstanding that if you don't have00:32:15
ID you can just create ID and it will00:32:18
work no it won't work we have to go00:32:20
through this Dynamics to create ID so00:32:23
don't try to recreate ID using Point00:32:25
number now if I disable this it will00:32:28
work perfectly fine can you00:32:35
see so just be clear whatever we get00:32:39
from here if you delete ID from here and00:32:42
if you try to recreate after that it00:32:44
won't work so you have to preserve its00:32:47
original ID so we have to rely on it00:32:49
when we have count changing right but if00:32:51
you don't have count changing then you00:32:53
don't have to worry about ID you can use00:32:55
Point number in that case see it's00:32:57
working fine so when there is Count00:32:59
change we have to heavily rely on ID so00:33:03
you will always search for IDs ID is not00:33:05
working then you have to Res simulate00:33:07
everything you need to check where you00:33:08
have deleted ID and like that so hope00:33:11
you understood the importance of ID you00:33:13
don't need to recreate it do network00:33:15
will create it for you next we have00:33:18
stream pop source and binding is set to00:33:22
it's fine so stream is naming of these00:33:25
so if you use x y z and after that if I00:33:29
M click over here that I have that00:33:31
Stream So it creates the group of these00:33:34
as well that's useful awesome next I00:33:37
will talk about this00:33:39
two let's talk about pop00:33:43
object I want to make some changes over00:33:46
here let's delete we don't need00:33:49
these and I want to add this bit in the00:33:52
air because we will check Collision as00:33:55
well now first frame and let's add00:33:59
gravity so here I can use this minus 900:34:03
or I can disable this and I have one00:34:05
more extra option which is Gravity Force00:34:08
so this is also better so let's go with00:34:10
this00:34:11
one and I have deleted everything so I00:34:14
want to use set everything and let's add00:34:18
this F and I want up direction00:34:23
also and let's just reset everything00:34:26
okay00:34:28
5,000 yep that's00:34:31
fine00:34:35
cool increase00:34:40
this most useful tab over here is00:34:43
physicals but before that let's just00:34:45
check out some parameters over here and00:34:47
at the moment we are using this pop00:34:50
source for now let me just disable it00:34:52
and if I just directly use this copy and00:34:56
and paste over here initial00:34:59
geometry it will just create00:35:02
that geometry over here and if I scatter00:35:06
some00:35:08
particles and if I use these I can00:35:12
just set right so here we have gravity00:35:16
that's why it's00:35:18
working so this is to set initial00:35:20
geometry if you don't want to use pop00:35:23
Source but it will emit on creation00:35:25
frame only00:35:27
but if you keep this creation from00:35:30
Dollar F meaning current frame number so00:35:33
if you so it will emit per00:35:41
frame best way to use this pop Source00:35:43
only for00:35:45
emission and I don't want to use this00:35:48
cool we understood initial geometry and00:35:51
here we have Collision also to check00:35:53
this we need00:35:55
Collision00:35:59
let's start with00:36:01
Crow and how do we connect this we have00:36:04
to use00:36:05
merge here it's written left input00:36:08
effect right00:36:10
input let's connect this to check it00:36:15
and yep now it's00:36:18
working and here we have option Mutual00:36:21
also so it doesn't matter where it's00:36:23
connected but it's better to use this00:36:28
for better00:36:32
organization yep it's00:36:34
working and let's just go to front over00:36:42
here let's just fix those stepping for00:36:47
now so to fix this over here also and00:36:52
let's just use00:36:54
positive forward right right so it will00:36:57
fix over here as00:36:59
well00:37:07
yep so tolerance is not so useful useful00:37:11
parameter is volume offset if I increase00:37:14
this it will create a gap over here you00:37:17
can see it's created 1 M00:37:20
Gap check00:37:24
this yeah00:37:32
and if I increase tolerance or something00:37:35
there is no00:37:38
difference right so everything is it's00:37:41
same00:37:49
only yep so next let's talk about this00:37:53
physics most useful parameter over here00:37:55
is two bounce and friction only let's00:37:57
explore others as well so this controls00:38:00
the bounce overall00:38:04
I but here if you have noticed you know00:38:07
that00:38:08
technically it should bounce and go this00:38:12
way right in this direction so if I00:38:14
increase this bounce forward will it00:38:16
solve the issue let's just check00:38:22
that no it00:38:25
won't00:38:29
why bounce forward is not working let me00:38:32
just reset for now let's just draw00:38:34
something so at the moment if you notice00:38:37
it goes this and it's making this00:38:40
moment what we need it should go this00:38:44
way00:38:46
and it should make this moment why it's00:38:49
not happening because of friction if00:38:51
object is not rotating on the surface it00:38:54
won't slide meaning it freezes is its00:38:57
rotation so it will go Direction but if00:38:59
it rotate then it will go in this00:39:01
Direction let me just show you rotation00:39:04
I have mentioned for understanding only00:39:06
but majorly it's using friction so it00:39:08
will slide right so let's just reduce00:39:10
this00:39:15
friction yep so now if I increase bounce00:39:18
forward it will move in this direction00:39:23
more right and there are two types of00:39:27
bounce so this controls the bounce00:39:29
forward and this is just bounce so if I00:39:32
increase00:39:34
this it will bounce in up00:39:40
direction see so these are the00:39:44
option yep it will work in and similar00:39:47
parameters we have here as well friction00:39:50
and bounce and everything and we have00:39:52
Dynamic friction also which controls the00:39:54
scale overall so if you reduce this it00:39:56
will slide00:40:02
more see so here majorly you will be00:40:06
touching friction bounds and temperature00:40:09
is not useful for now yeah00:40:12
here next I will talk about00:40:16
collisions cool let's talk about00:40:19
Collision so here let's understand does00:40:21
particle collide with each other so no00:40:23
it's too tiny so it doesn't Collide but00:40:26
if you want to add particle collision00:40:28
then you have to set P scale P scale we00:40:31
will talk about when we render this but00:40:33
for now let's just understand so you can00:40:35
just set a p scale basically radius of00:40:38
the particles and after that you can run00:40:40
a grain solver so it will collide each00:40:42
other and also if you want to add00:40:44
Collision it will increase five times or00:40:47
10 times simulation time00:40:55
also00:41:21
yep so this particle collide with an00:41:23
object let's add Collision object now so00:41:26
we need box over00:41:36
here let's select this00:41:50
template yep that's00:41:55
fine00:41:57
so how do we read this we have to use00:42:00
static object over00:42:05
here if I check static object I have00:42:07
some options over here object name is00:42:10
this thing so I can just name it box and00:42:15
second thing is sof path we need sof00:42:18
path over00:42:21
here yeah so it's not visible at the00:42:25
moment so you can just connect this over00:42:27
here so now it's visible let's run the00:42:31
simulation it won't Collide because here00:42:35
it's following this rule right so here00:42:37
we can just add00:42:40
merge and and over here or else you can00:42:44
just use this also but it will be too00:42:47
complicated right you cannot just merge00:42:49
multiple over00:42:52
here can you see it's colliding00:42:55
now00:42:57
but best with is this merge00:43:00
Collision let's disconnect this and00:43:03
connect over00:43:05
here if you have multiple collisions you00:43:08
can just merge over here and now let's00:43:10
just00:43:12
check so it's working now let's study00:43:15
some parameters over00:43:17
here so first step we have physical00:43:20
which we already studied and we have00:43:22
some other parameters also over here00:43:24
object transfer create activ and00:43:26
everything let's just check some of00:43:28
them I will explain use deforming later00:43:30
but first let's understand what is use00:43:32
object transform so it's just if I use00:43:36
box over00:43:38
here right and I will just00:43:40
transfer at object level and I'll just00:43:44
copy00:43:47
this and paste over00:43:55
here00:43:57
as you can see it's right there if I00:43:59
turn on object transfer it will follow00:44:01
that whatever we have over here let me00:44:05
delete00:44:09
this paste over here so we don't want to00:44:11
use this and what is active object an00:44:14
active object it won't do anything we00:44:18
have to use rigid body00:44:23
Dynamics let me connect this and here00:44:26
here it won't00:44:28
work because it's set to bullet and we00:44:31
have to use RBD over here so I will just00:44:34
explain this also in some time now you00:44:36
can see yeah that's just00:44:41
brief and ignore merge relationship is00:44:44
just collisions so it won't Collide so00:44:48
whatever connection we have over here it00:44:50
won't00:44:54
work00:44:59
great so now let's talk about deforming00:45:01
so let's add some deformation over here00:45:03
it's static at the moment so I can just00:45:05
type dollar F multip by 3 so I want to00:45:08
use current frame and I want to multiply00:45:10
by three so it will rotate00:45:12
faster let's just00:45:15
check so as you can see it's not00:45:17
rotating I can just turn this on and00:45:20
let's check00:45:24
output00:45:29
so as you can see it's a collision issue00:45:31
right so you can see some stepping some00:45:33
gaps over here and how do we fix it00:45:36
first let's understand reason behind it00:45:39
so in this case we need in between Frame00:45:42
data for example first frame second00:45:45
frame and third frame at the moment00:45:47
simulation is running this way right if00:45:50
object is rotating this way right and00:45:54
this is second frame right so I want00:45:57
information in this area also so we have00:46:00
to run00:46:01
this in between frames this way and here00:46:05
we have to use00:46:06
substeps so let's just set00:46:12
substeps if I increase substeps will it00:46:14
fix let's just check00:46:21
it so it's not fixing that much and here00:46:26
let's just check second parameter also00:46:28
it mentioned that it will solve in00:46:30
between data also meaning it will just00:46:32
interpolate geometry so let's just check00:46:34
will this work or not I'll just stay on00:46:37
this Frame let me just00:46:41
reset no there is no difference this00:46:44
option is not useful in this case so now00:46:47
what to do here we have to check this00:46:50
let's just select this over here and if00:46:53
I go and disable this integer00:46:57
frame then I have in between Frame data00:47:01
so if I run you can see it's not moving00:47:05
in between00:47:06
frames why because I'm using dollar F so00:47:09
I need floating frame so I can just type00:47:14
dollar FF over here and if I run you can00:47:18
see I has smooth M and now let's just00:47:22
check so I'll just stay on the frame I00:47:25
two sub steps let's just00:47:30
reset yep it's solving that00:47:35
issue so that's what you need to00:47:37
understand over here this is how it00:47:39
works and the more substeps you increase00:47:42
the more it will fix these00:47:44
things and now let's talk about this00:47:47
Collision tabes so this is most useful00:47:49
over here and you will have to always00:47:51
check this thing so if I scroll down I00:47:54
have some parameter over here and I'll00:47:56
just ignore everything and just click00:47:58
this guide geometry and let me just00:48:02
disable this over here so this is what00:48:05
basically a collision so you have to00:48:08
always check this and if you have any00:48:11
open polygon let me just00:48:14
delete right so I have this open polygon00:48:17
you can check this change the shape also00:48:21
now right see so if you have over here00:48:26
it will just00:48:27
bounce and if you have open polygons00:48:29
just always use00:48:34
polyfill and make sure you you always00:48:36
sent a watertight mesh so you won't have00:48:39
any00:48:54
glitch let me delete00:48:57
everything so let me just disable this I00:49:00
don't want in between frames here have00:49:02
you noticed something that it's creating00:49:04
this mesh every frame and it's kind of00:49:06
jittery00:49:08
sometimes and what's happening over here00:49:10
it's using this mode R intersect and if00:49:13
you want to increase the resolution you00:49:15
can just go and increase over here and00:49:19
there are other options over here as00:49:21
well but those are not useful just you00:49:23
can use00:49:24
these00:49:29
but it will affect simulation time also00:49:31
and if you keep this visualization on it00:49:34
will take more time if you turn this off00:49:36
and turn on this then it will take00:49:38
lesser00:49:39
time it's creating volume on every frame00:49:42
that is also one reason it's creating00:49:44
those gaps and in fact we can fix that00:49:47
without substeps also so I had talk00:49:49
about this volume and next step we have00:49:51
surface as well and let me just turn00:49:55
this off off and you can see it's clean00:49:57
geometry it's not a volume and this is00:49:59
exact surface whatever we are providing00:50:02
it it will use that and let me check00:50:05
does it fix that issue let's reset00:50:08
everything so we don't have00:50:16
substeps so it's not so here we need to00:50:20
understand if we turn this on it won't00:50:22
utilize this surface option so we have00:50:24
to use this00:50:26
use surface Collision now and I will00:50:29
just stay on this Frame and I will just00:50:31
reset this so you can just immediately00:50:32
see the00:50:33
difference yeah it's fixing it without00:50:37
subst steps and it's too00:50:39
fast we are using very simple geometry00:50:42
Collision right but if you have complex00:50:44
geometry in that case it's very00:50:47
expensive and it may crash your00:50:49
simulation also sometimes so still you00:50:51
can optimize your geometry and use this00:50:53
option but I will recommend you to use00:50:56
this volume but not R race you have00:50:59
other option volume00:51:01
sample and there are other options as00:51:04
well but those are not so useful you can00:51:06
just use volume sample that's most00:51:08
recommended and let me just reset00:51:10
everything and how to use this over here00:51:13
so if you use00:51:15
this we have one more parameter over00:51:18
here let me just reset you have00:51:20
parameter over here proxy volume and00:51:22
let's just use that so here I'll just00:51:25
use00:51:27
Collision00:51:29
Source first input is00:51:36
this proxy00:51:38
volume and you can see we have some00:51:41
volume over here and you can control00:51:44
this in second tab Collision so this is00:51:46
the00:51:47
wxel and you can even create this also00:51:49
it's just VDB from00:51:54
polygons00:51:58
it's same only benefit of this node read00:52:02
it will calculate in between frames and00:52:04
it will add velocity also so it's better00:52:06
to use this and let me just00:52:09
copy and paste over00:52:15
here cool so I'm using this volume00:52:17
collision and let me turn on collision00:52:19
guide so at the moment it's using Ray00:52:21
intersect let me use volume sample now00:52:28
yep and I have to turn this off filation00:52:32
in order to turn00:52:43
faster and we know how to fix it if you00:52:46
have clean geometry you can just switch00:52:48
to this use surface Collision but if you00:52:50
have complex geometry in that case you00:52:52
can just increase subst steps so in this00:52:54
kind of case it makes using00:52:57
substeps but don't use substeps to fix00:53:00
those stepping created by moving source00:53:02
so I have created a tutorial on YouTube00:53:04
you can check that later and substeps00:53:07
also helps to calculate extra moment in00:53:10
short frame it can be useful for C00:53:12
mushroom00:53:16
blur and let me just show you what this00:53:19
parameter so this parameter is not so00:53:21
useful if I turn this on it stays the00:53:24
same00:53:28
yep so y I will recommend you to check00:53:31
all the steps and everything and you can00:53:34
just increase this four so it will fix00:53:36
it yeah so whenever you increase sub00:53:39
steps it will increase simulation time00:53:41
also yeah so now it's00:53:46
fixed cool let me reset everything00:53:50
now and we understood this volume and00:53:53
difference between volume and surface00:53:55
you can utilize in some cases and you00:53:58
can utilize this also in those heavy00:54:01
geometry cases and second type over here00:54:03
is bullet data so you have to remember00:54:06
that if you're using particles or flip00:54:09
it will use this RBD solver but if you00:54:12
are using rigid body solver remember we00:54:14
have used this if it's set to this00:54:17
bullet it will utilize this collision00:54:20
and if you use this RBD it will utilize00:54:23
this thing over here so in part IC it's00:54:25
not00:54:26
useful and next let's talk about pop00:54:29
solver so here we have substeps and time00:54:33
scale it will increase particle movement00:54:35
overall so if you reduce this it will00:54:37
slow down00:54:39
particles and let me just disable this00:54:44
Collision yeah and if I increase this by00:54:47
10 it will move00:54:54
faster00:54:59
in a small scale you have you're00:55:01
simulating in you need faster moment so00:55:03
you can use this and next is minimum and00:55:05
maximum substeps so we have Global00:55:08
substeps also and we have extra control00:55:10
over here as well so you can use this00:55:13
minimum and maximum so the solver will00:55:16
decide when to use minimum and when to00:55:18
use [Music]00:55:23
maximum so for example if you need High00:55:26
calculation in this Frame it will00:55:27
utilize this Max and if you have faster00:55:29
simulation and not that Collision so it00:55:31
will utilize this two it will switch in00:55:34
between yeah these three parameters you00:55:36
will mostly use second tpe is update00:55:39
here we don't have to change anything00:55:40
but just brief I can just00:55:42
explain so if you want to avoid00:55:45
calculating age particles or use mass or00:55:48
if you want to use these so let me just00:55:49
show00:55:54
you00:55:57
and you can see this particles are dying00:55:58
over here and I don't want to calculate00:56:03
that so it won't kill those particles so00:56:06
those kind of stuffs we have but it will00:56:09
affect the attribute so there is the00:56:10
dead attribute which I'll will explain00:56:13
later cool next we have Collision00:56:15
Behavior so let me just turn this00:56:23
on00:56:32
here we have option to Define what it00:56:34
should do on collision so at the moment00:56:36
it's colliding over here so you can just00:56:38
add into some group or you can add a00:56:40
color so you can just create a Collide00:56:43
group so whatever is collided and you00:56:45
can add different force on that00:56:50
thing right so these are the collided00:56:53
you can add extra drag on that00:56:57
thing and here you can set a response00:57:00
what it should do it can stop over00:57:08
there right so you can check this it00:57:11
stopped over00:57:14
there and those are the slide and other00:57:17
options are also there and we have one00:57:18
more option is attributes so here you00:57:20
can just add Heat number heit position00:57:23
and this can be useful if you want to00:57:24
create laser simulation you can just00:57:26
find heat frame heat time hit position00:57:29
those kind of stuffs we have and next is00:57:32
slipping let me just disable00:57:36
this so you have noticed over here00:57:39
particles are keep sliding over here and00:57:41
if you want to make them static in some00:57:44
time so you can just turn this on and00:57:47
here we have velocity threshold so if00:57:49
you increase this particle speed goes00:57:52
below this velocity threshold it will00:57:54
stop00:57:59
that range is not working so you can00:58:01
increase it let me just pin this over00:58:03
here00:58:07
reset y now it's00:58:11
working let me just use three00:58:23
only00:58:33
four it means particle mement is more00:58:36
than four so that's why it's not00:58:38
stopping over here minimum is five so it00:58:40
will just stop00:58:52
there see so it's it's just stopping in00:58:57
there and here we have slip de so you00:58:59
can see it's just sto in the middle of00:59:01
the air so you can just add two so it00:59:03
will00:59:05
gradually slow00:59:18
down cool so you can just use slipping00:59:21
color also00:59:23
now00:59:31
it's activated activated here and to00:59:34
control this kind of stuff we have other00:59:37
thing as well you know so at the moment00:59:39
it's following constant speed right so00:59:41
if you use this increase friction00:59:44
dynamic range and let me just reset00:59:46
everything over00:59:48
here and now it won't slide that00:59:52
much see so let me just use use this00:59:55
much00:59:59
only01:00:03
yeah I have to reduce this even01:00:09
more01:00:12
yeah see now it's not sliding that much01:00:14
now so you can just play around with01:00:17
this value so it will01:00:23
stop01:00:27
yeah see now it's below one that's why01:00:31
it's stopping over01:00:33
there so this is the01:00:36
threshold start a slip whatever is01:00:39
emitted on first frame meaning01:00:41
simulation frame first simulation frame01:00:43
it will be inactive and at the moment we01:00:46
have continuous amission right so let me01:00:48
just emit on first frame only so here I01:00:51
want to01:00:52
use impulse activ acation01:00:56
zero and I want01:00:59
1,00001:01:02
yep see it's not moving01:01:05
now and if I turn this on it will01:01:11
move if you have continuous emission it01:01:14
won't01:01:19
work cool so next is binding and01:01:22
distribution it's useful for five minut01:01:24
St cool that's all that's just basics of01:01:27
particles and this was just a brief of01:01:30
all these parameters and don't worry if01:01:32
you didn't understand some parameters so01:01:34
now we will create fireworks and it's01:01:36
always easy to understand things with01:01:38
example so let's create fireworks01:01:41
next let's create01:01:44
fireworks I will delete everything I01:01:47
don't want anything over here so I'll01:01:49
just need01:01:52
sphere so I'll use this as a source to01:01:55
Adit particles and let me just rename01:01:58
this particle01:01:59
[Music]01:02:01
Sim yeah this is my source all we need01:02:04
is01:02:08
popnet so I will get this node flow over01:02:10
here01:02:12
and yep it's emitting01:02:16
now01:02:18
cool we have to set a velocity right so01:02:20
it will go in up Direction but at which01:02:23
speed so let's just Google it so if I01:02:25
search this it's saying that fireworks01:02:28
speed is 45 m/s right so we can use01:02:32
this and here we need to just use and01:02:36
can just set this over here and we can01:02:38
use 45 over01:02:44
here yep so this is the01:02:46
speed so at the moment I'm able to01:02:49
follow real speed like 45 m/ second01:02:52
right but in production you will have01:02:53
camera you will have Sky level as well01:02:56
in that case you have to set value01:02:58
according to your scene and based on01:03:00
that you have to visually match the01:03:02
speed so you know follow some reference01:03:03
in that case and check how fast it's01:03:05
moving so accordingly you can just match01:03:07
the speed so you can just set this 2001:03:10
and keep your reference over here and01:03:13
just check it's matching the speed no01:03:15
just increase it 45 47 it's up to you01:03:19
right so this is not exact value you01:03:21
have to follow you need to just set01:03:23
everything according to your seen01:03:24
whatever is there in the screen it will01:03:26
sell so you have to work01:03:29
accordingly yep and I have lots of01:03:32
particles over here I want reduce maybe01:03:34
let's use let's use one only because it01:03:38
doesn't emit that much here I can use01:03:40
anything over here if I use this it will01:03:41
continuously emit see I don't want that01:03:45
I want one particle one or two particle01:03:47
per01:03:51
second Yep this is01:03:53
best yeah see it's creating random Gap01:03:59
also cool next one I need is Trail and01:04:03
how do I create a trail because these01:04:05
are single particles and there is always01:04:08
a trail right so let's create Trails for01:04:11
that I need pop01:04:14
replicate and here if you check it's all01:04:17
same whatever we have learned over01:04:20
here it's similar only so what is new01:04:23
shape and Noise01:04:25
I just I will briefly explain this tool01:04:27
in some time but let's just connect this01:04:29
let's connect this over here and01:04:33
check so is it01:04:36
emitting yes it's emitting over01:04:40
here but at the moment it's just01:04:43
following same speed so we have to go to01:04:45
attribute and we can just reduce inherit01:04:48
velocity over here so let's just reduce01:04:51
point1 and check01:04:55
yep can you see it's creating a01:05:06
trail and that's too long trail so I01:05:08
want to01:05:09
delete life01:05:13
also yep that's fine01:05:23
see01:05:26
and what is the second input over here01:05:29
let's connect that or also so it says01:05:32
it's a reference over here and what is01:05:34
this01:05:35
reference so it won't emit anything over01:05:37
here so it will use this as a reference01:05:40
so it won't simulate this01:05:45
separately that's fine01:05:49
now and here we already know how things01:05:52
Works let's just check what is shape01:05:54
over here and shape is nothing but it01:05:57
will just create some shape if I use box01:06:00
and I can increase01:06:03
this let me reset over here yeah you can01:06:07
see it's box over here let me increase01:06:10
count so you can just clearly see01:06:13
this yep it will follow box shape so I01:06:16
don't want shape over01:06:19
here but before that let's just add01:06:21
noise so you can see it looks too boxy01:06:23
right so if you want to add additional01:06:25
noise on that you can do that also see01:06:27
it will add some01:06:30
noise on top of that these two are01:06:32
useful to change shape of emiter but you01:06:34
can just disable this and I want sphere01:06:37
and scale is01:06:40
zero yep as you can see and here I want01:06:45
to add some variance we can see some it01:06:48
will will01:06:50
have this Trail over here and again is01:06:54
creating stepping over here so let's01:06:56
just straight away go and increase sub01:06:59
steps to fix01:07:00
it yep it will fix but let's understand01:07:03
these things never use substep directly01:07:06
always find some alternate solution to01:07:08
fix this kind of stuff so let's just01:07:11
understand why it's happening over here01:07:13
so this is the main point we have and01:07:16
it's creating this01:07:19
particles so why it's creating Gap all01:07:22
of them has same speed right so it's01:07:24
inheriting so this has one this has one01:07:27
right so what we need is we need some01:07:29
range in this thing so it if we have01:07:32
random then it will fill this Gap so at01:07:35
the moment particle is moving in this01:07:37
Direction that's fine and whatever is01:07:40
emitting also it's correct it's totally01:07:42
correct because we are not simulating01:07:44
this in between frames right if you if01:07:46
you want to calculate that precise in01:07:48
between frames in that case you have to01:07:50
use substeps then only it will just read01:07:52
this and fill this Gap01:07:54
technically but I don't want to take01:07:57
extra simulation time or something01:07:59
that's why I'll just find a quick01:08:00
solution so in that case we can just use01:08:08
Dr so here is the reason here I want to01:08:11
apply drag on these particles only not01:08:14
on this so if I have used this over here01:08:16
I had to apply on both of them right so01:08:20
it's fine now I can just apply on01:08:22
emitted particles and I can just01:08:24
name them also01:08:26
drill yep and by default it's one so01:08:30
that's not so01:08:32
useful What I Need Is Random so I'll01:08:35
just go over here so this thing is very01:08:38
useful always use this so whatever we01:08:41
have over here and remember I have01:08:44
discussed about the ID it has random01:08:47
value so we will utilize that only so01:08:49
can just type or go here it's air resist01:08:52
so don't type air resist assistance it's01:08:54
air01:08:55
assist01:08:57
air right so I want to use this01:09:02
multiply and random at01:09:06
ID and I want to use from fit 0 to01:09:17
1 so take a screenshot of this this is01:09:20
the most useful Vex and I will explain01:09:22
in sometime what happening but let's see01:09:25
the01:09:27
result so why there is no difference01:09:29
because we have reduce over here as well01:09:31
so I want to use first this and let's01:09:34
just01:09:35
play yep it's fixing still it's not01:09:39
fixing over here so I want to reduce01:09:42
this01:09:46
.1 it's01:09:50
fixed that's just nice and easy way to01:09:52
fix01:09:55
and I can just spread this from here as01:09:57
well so I can just increase01:10:00
this yeah but that looks too uniform01:10:03
right so I'll will just use pop01:10:06
force and this is right time to explore01:10:09
pop Force01:10:12
also so here we have some parameters01:10:15
this is force in which direction you01:10:17
want to add this so you can add some01:10:20
wind also on these things it will look01:10:22
cool01:10:25
see right so I don't want winds what I01:10:29
need is this wall noise and what is this01:10:32
SW size SW scale pulse length and01:10:34
everything over here we have that this01:10:35
is amplitude over here and I want to use01:10:38
amplitude one let's see over here no01:10:42
difference let's increase 1001:10:47
times yep now you can01:10:51
see yep that's fine01:10:54
so what is the SW size so SW size01:10:57
basically a noise scale so if I use box01:11:00
over01:11:01
here and this is what it will apply so01:11:05
at the moment S size is one so it will01:11:08
apply this01:11:09
noise and same we have control in axis01:11:13
as well and pulse length is basically01:11:18
speed how fast noise flow you want over01:11:22
here01:11:40
so how this is works is if I reduce01:11:42
pulse length it will increase noise01:11:45
speed and if I increase pulse length it01:11:48
will reduce noise01:11:52
speed01:11:58
let me just explain you quickly and here01:12:01
it's not visible clearly but let me use01:12:04
grid to show01:12:08
you yep and let me increase01:12:13
this yeah see let's just stay on this01:12:18
Frame and pin this let's increase01:12:21
particle count also so these are the01:12:24
things that you will mostly use and just01:12:26
understand these things01:12:34
clearly yep and as you can see it's01:12:38
travel too much right so if you reduce01:12:40
this thing over here it will travel less01:12:43
let me reset01:12:45
this let me just go one frame yep so you01:12:49
can just clearly see the difference and01:12:52
reference is extra noise it will just01:12:54
break the noise more with high frequency01:12:57
and there are other options as well but01:12:59
that's all for01:13:01
now let me just delete01:13:04
this we understood this part so I don't01:13:06
want to change anything just keep and I01:13:09
will01:13:13
reduce this life over01:13:21
here yep that's fine01:13:27
and I want to talk about this Vex now so01:13:30
what's happening over here so air01:13:32
resistance is one so if you use air01:13:35
resistance it will slow down the01:13:37
particles it will work as a01:13:38
atmospherical drag you know we have wind01:13:41
that slow down things that's what we can01:13:43
use this as a drag it will start with01:13:45
the speed and it will gradually slow01:13:47
down the speed overall using this track01:13:49
and here we have just wind velocity also01:13:51
you can set in which direction it should01:13:54
move and air resistance is a drag01:13:56
basically overall and why I'm using this01:13:59
fact so if I use air resistance it will01:14:01
assign one value one drag to all01:14:04
particles so all particle will slow down01:14:07
at same time that's not what I want so01:14:09
here I will use some V So Random ID so01:14:12
what is random ID let's just understand01:14:14
so if I have multiple ID over here01:14:16
meaning five so this is from 1 to five I01:14:21
have right so it will just use randomize01:14:23
it and it will give me from 0 to 1 so it01:14:27
will we will have gradient between that.01:14:31
56.8 so it will randomly assign on all01:14:34
of these five01:14:35
particles and I will just use this Fit01:14:38
value over here so as you can see that I01:14:41
have zero also over here right so I01:14:43
don't want that zero I want 0.1 instead01:14:46
because if I use zero then it will be01:14:48
too fast it will apply zero a resistance01:14:51
and that's not what I want and I have01:14:53
have Max one is fine but here you can01:14:55
just use two also it will fit by two so01:14:59
that's what this VX is doing over01:15:03
here and that's a quick way to fix this01:15:06
kind of01:15:07
stepping and let's just add ramp color01:15:15
also and I want ramp so by default it01:15:19
set something over here let's just01:15:22
see01:15:24
and I want reverse of01:15:27
these oops it's not01:15:29
moving let me use this01:15:35
black and we can just use yellow that's01:15:38
fine01:15:43
see and this ramp is using something01:15:47
called NH and what is this NH but before01:15:51
that let's just check do we have that01:15:54
attribute let me search for NH so we01:15:58
don't have that attribute so NH is a01:16:01
hidden attribute over here and let's01:16:03
just talk about01:16:06
it and this is right time to explore01:16:08
geometry spreadsheet also so let's go to01:16:11
Geometry spreadsheet over here and we01:16:14
have multiple things over here so you01:16:17
just need to focus on this point because01:16:19
we are working on point just select this01:16:21
node and click this points01:16:24
and here we have lots and lots of01:16:25
attribute over here so not all of them01:16:28
are useful right so we can just filter01:16:30
them out one by one so let's this is01:16:32
position so it's Point position and here01:16:34
we have age and how age is working so if01:16:38
you01:16:39
see in the start frame it's01:16:43
zero and it01:16:48
increasing and next is a resistance that01:16:51
we have already talked about right so01:16:53
you can see that we have range over here01:16:56
let me just pin this and let me disable01:17:00
that pop01:17:02
drag so now we don't have air resistance01:17:05
over01:17:07
here so that's what creating that01:17:10
thing and we can just use we can disable01:17:13
this wax also now we have all of them01:17:15
one01:17:18
only that's how it01:17:21
works yeah now let's understand what is01:17:24
NH so how NH calculates it uses this age01:17:29
and life over here so let me just filter01:17:32
them age and life so I'll just focus on01:17:36
age and life only so 100 is those two01:17:39
particles life of this thing and that01:17:42
also we will talk about when it should01:17:44
burst in next01:17:46
video so it will divide this age by life01:17:50
so this age moves from 0 to.5 because we01:17:53
have this life so you won't see01:17:56
particles above01:17:57
05 it won't cross that value here it's01:18:01
Crossing because we have this life is01:18:03
100 so that's01:18:06
fine to explain you this quickly let me01:18:09
just use some01:18:10
Vex and I want grid over01:18:13
here just this is for explanation that01:18:16
what is happening in the back end I'll01:18:17
just use Point triangle so I have this01:18:21
age I want to create a parameter and I01:18:24
have this life which01:18:26
is05 and I want to calculate NH H01:18:30
divided by01:18:35
life let me un pin this sorry I have to01:18:39
mention this at so interesting part is01:18:42
it won't show this anage over here01:18:44
because that's hidden attributes so here01:18:46
you have to change this to capital N to01:18:48
visualize this and it's not only that01:18:51
you can use XYZ also just different from01:18:55
NH and let's just check let me create01:18:59
this and this is my particles it's aging01:19:03
aging aging aging so if I stop at01:19:07
05 it's one so NH is a basically a value01:19:12
from 0 to one and you need to clearly01:19:14
understand that how things work because01:19:16
that's most useful and based on that01:19:18
only we will just add some color01:19:20
variation and01:19:21
everything01:19:24
right so you need to understand this01:19:25
mathematics little mathematics behind01:19:28
it and in this example it will cross but01:19:31
in particles it won't cross because we01:19:33
have set age limit there five it will01:19:36
stop and delete the01:19:40
particle cool that's understood let's01:19:43
delete this clear and know how to use01:19:45
this geometri spread sheet01:19:48
also and you know if I select this it01:19:50
will show lots of confusing stuff that01:19:52
you you have to go inite just create01:19:55
null and just it will be easier for you01:19:57
to explore things for01:20:00
here yep you can track everything over01:20:03
here ID particle hit points01:20:08
everything01:20:14
cool let me press L to organize01:20:21
things so so next we will talk about01:20:24
bust and how to set bust timing and01:20:28
everything let's talk about bust and01:20:31
here if you have camera and can just01:20:34
bust this at at here here I want to01:20:37
follow real value so let me Google it at01:20:40
what height do fireworks bust so it says01:20:43
it bust at 60 M or 150 M so let me use01:20:47
box over01:20:50
here and here I'll just copy this and01:20:54
paste this for here by01:21:00
two so whatever is there I have unpin it01:21:05
yeah so if I don't use this then it will01:21:08
be like01:21:09
this whatever I increase over here it01:21:11
will be there and I have to change this01:21:14
manually so I can just link01:21:17
this it will increase that here I can01:21:21
just start with 60 which is minimum01:21:23
range and I can even increase this by 7001:21:26
also that's fine it's up to you so I'll01:21:30
just keep go with 70 again I'm01:21:32
mentioning you don't have to follow the01:21:33
same value or everything depends on your01:21:37
on your reference scale and how fast you01:21:39
want for now I'm just following these01:21:41
things to explain you that we can follow01:21:43
some real value also and how we can01:21:45
implement this for here I'll template01:21:50
this okay so it's going above that thing01:21:53
so I need to kill this at this thing01:21:55
over here let me reduce this by one so01:21:58
it will delete right01:22:07
there let me just move this so I can01:22:17
see yep I01:22:20
want five that will work01:22:35
so I think I can use 1.501:22:43
also yep 1.5 works01:22:49
well and how do you bust but before that01:22:52
let's add some01:22:55
gravity so here we can just use pop01:23:00
force and I will just straight away go01:23:03
in minus because that's what gravity is01:23:07
let me just check now I have to compare01:23:08
this now because it will change01:23:11
everything because whatever bust we have01:23:13
it should follow the gravity right so01:23:15
that's why I have to add gravity01:23:18
now yep so I have to increase it01:23:24
1.5 that's01:23:28
was yep it's01:23:31
correct how do you bust this thing so01:23:35
for that also we have to use pop01:23:41
replicate and here you won't connect01:23:43
this you will connect this as a01:23:46
reference because this is the mainstream01:23:48
we have it will simulate this thing and01:23:51
it will use this as is a reference and I01:23:54
want to bust particles when it dies so01:23:57
how we can find out that value when it01:23:59
dies so for that we have to again go to01:24:04
this geometry spreadsheets so that's why01:24:07
it's very very useful so let's just01:24:09
search do we have anything related to01:24:11
that or something so we have that01:24:14
attribute so let's just filter out that01:24:16
and just study it what is01:24:19
doing okay so it's always zero01:24:23
and why it's always zero because01:24:25
whenever particles dies this value turns01:24:28
into one and that's not visible because01:24:30
particle is dead till then to just01:24:33
visualize that we can just turn this off01:24:36
R particles means it will delete so I01:24:38
don't want to delete particles I want to01:24:40
keep them in the scene so you can just01:24:42
check so these are dead particles and I01:24:46
want to utilize01:24:48
them in Geometry spreadsheet it's not01:24:51
visible from from 0 to 1 because it's01:24:53
stad but01:24:56
inside here it's01:25:00
visible and let me just show you that so01:25:03
for now I'll01:25:05
just disconnect this and here I can just01:25:08
use group and I can just easily type01:25:10
dead is equal to01:25:13
1 and let's see the01:25:15
magic it's working that's what we01:25:21
want01:25:23
and now let's quickly make some changes01:25:25
here we can just use zero or we have01:25:28
other option is points where we don't01:25:30
have scale so that is also we can use01:25:34
and I don't want to use this now impulse01:25:36
because I have one frame only to emit01:25:39
things in that case I will go with this01:25:41
I want 10001:25:45
points yep so bu I need add inheritance01:25:49
let's just increase them01:25:57
that's the magic and here we have01:25:59
gravity also and it's inheriting that01:26:02
value and I don't want that much so01:26:04
let's just use by01:26:09
three yep I can reduce this also and01:26:13
here also I will add01:26:15
drag because drag is01:26:18
must okay I want to kill particles so01:26:21
here I can just use01:26:28
one okay so all of them are dying at01:26:30
same point so that's not what I want so01:26:32
I can just go here01:26:34
copy01:26:37
paste divide with two so I will have01:26:39
some range over01:26:43
here yep you can see some particles are01:26:46
dying sooner and some particles are01:26:48
later so that's fine and here also I'll01:26:51
just give it some life variance because01:26:54
here I want some longer life01:26:57
variant so some to die01:27:02
quickly and here also I'll just copy01:27:06
this oops I'll copy this and paste over01:27:15
here and it has Slow Down Speed a lot so01:27:18
I want less only maybe I can use five01:27:24
see it's reduced a lot I think 35 will01:27:28
be01:27:33
fine01:27:38
yep yeah it's time to set a camera over01:27:40
here now so let me this is max range we01:27:44
have set a01:27:46
camera that's01:27:51
fine01:27:58
oh I have to move my camera now so to01:28:01
move my camera I can just go here lock01:28:03
and move01:28:04
back so I can just capture everything01:28:08
yep cool let me turn on my01:28:21
trail01:28:26
and here I want some life01:28:33
variation divided by01:28:36
two and you can just reduce particles01:28:38
count also 2,000 that's01:28:41
[Music]01:28:51
fine01:28:54
and here also we need01:28:59
Trails I'll just copy this same thing01:29:02
over here and01:29:05
paste and let me just connect01:29:08
this it's bu01:29:13
tril I need same and I can just change01:29:16
the color to Red so I can see the01:29:19
difference here also I have to connect01:29:22
this01:29:24
additionally let's just01:29:27
check01:29:31
yep everything is working and here you01:29:34
have noticed the count is too much right01:29:36
so I can just reduce01:29:37
[Music]01:29:39
count5 is fine and here also I want01:29:46
05 and let me reduce this01:29:50
variance and here also I should reduce01:30:00
that01:30:03
yep we have control over01:30:08
particles let's just check01:30:11
drag and let me just increase that by01:30:14
two because I need to slow it down01:30:20
more yep and let me unlock this camera01:30:24
so I can avoid moving it01:30:46
again that looks cool I know it's really01:30:49
simple example but here we have learned01:30:51
a lot about how age Works how that01:30:54
attribute Works how to bust things for01:31:04
here and here I'll just make some01:31:06
changes so always just work on random01:31:08
things that all of them follows some01:31:10
different different noise frequencies SW01:31:20
size01:31:27
and let me just check the parameters one01:31:30
more time what I have01:31:32
changed so that's fine here we are using01:31:36
this drag pop01:31:39
Force01:31:41
color let's just organize01:31:50
this01:32:04
let's go more crazy now so here we know01:32:07
we have bust this this thing right what01:32:11
I want to do over here I want to bust01:32:14
extra this particle also and not all of01:32:17
them I want to use some ratio you know01:32:19
where I can just select 50% partic 30%01:32:22
particle let's use01:32:26
that and again I'll just create01:32:28
everything build everything from scratch01:32:30
so you can just revision also you know01:32:33
if I fast forward some part over here so01:32:35
now you can understand one more01:32:40
time okay so that's just01:32:44
burst and I will use pop replicate again01:32:48
and that is second Buton01:32:53
first and whatever I'm naming over here01:32:56
I will use them as a group letter so01:32:58
make sure you just name things01:33:00
clearly yep let's just connect01:33:03
them and this is my second bust so I'll01:33:08
just keep it separate and connect01:33:11
this okay so before that here also I01:33:14
need to set a group if I set a group01:33:16
over here then I have to use all of them01:33:19
where I don't have any01:33:20
control in that case let me just disable01:33:24
it I will use pop group to separate out01:33:28
those01:33:29
particles and I have to keep that in our01:33:35
system so if I check pop group I have01:33:38
some parameters and I'll will talk about01:33:40
main parameter only so which is group01:33:42
name which is second bust so I want to01:33:45
create a group over01:33:47
here and source group is that thing01:33:53
dead and here we cannot visualize01:33:56
anything but here we have option to turn01:33:59
this01:34:00
on that's the chance currently set to01:34:03
50% let me just play01:34:07
it and let's just use that group so here01:34:10
now connect this and let me just copy01:34:14
this second01:34:16
bu group over here and again I had to01:34:20
make some changes01:34:22
so I can just keep everything same I01:34:25
want to use01:34:27
Point add over here let's just Increase01:34:30
by.01:34:35
five see it's01:34:37
working so it's currently using 50% and01:34:41
I don't want that much so let me reduce01:34:47
it yep okay I'll can reduce it even more01:34:51
I want tiny you know 1%01:34:55
only yep see you can see it here you can01:34:59
see it over01:35:00
here maybe you can increase a little bit01:35:03
5.2 that's01:35:10
fine yep it's working perfectly fine and01:35:14
here also I want drag so let me just use01:35:19
drag pop drag01:35:22
so after that we can set some value over01:35:25
here know before drag it will01:35:29
be so we know what we need to do a01:35:32
assist just type clearly over here so we01:35:35
know fit and I don't want that let me01:35:38
use use half of01:35:43
that yep now you can01:35:48
see here also I want to set uh01:35:52
life1 by .1 and I can set impulse01:35:56
because that's not enough points so01:35:58
let's use 100 points at once so on each01:36:02
bust it will emit 100 points see now we01:36:05
have good01:36:09
quantity and if you want you can add01:36:11
additional bust also it's up to you but01:36:14
it's fine I'll just stop right01:36:17
there yeah but trailing is must we have01:36:19
to add trailing so we will use pop01:36:22
replicate again I'll reference01:36:28
it I have to connect01:36:31
this so I can just type01:36:34
second bust tra type very clear so you01:36:40
can understand after cache let me play01:36:45
it yep that's01:36:48
working yep so here I have to just red01:36:51
edce the life overall and I can add some01:36:56
variance over here so you can just01:36:58
spread01:37:03
more01:37:05
yep and on shape also I need to use01:37:09
point so it will emit from the01:37:12
point and01:37:15
see oops it's not reset01:37:20
yet01:37:25
yeah that's happening because of the01:37:28
inheritance so we have to use drag over01:37:31
here now so I'll just use drag and I01:37:33
want to use extra drag because you can01:37:35
see it's shooting a01:37:38
lot let's01:37:41
play01:37:42
yep01:37:44
yep01:37:46
beautiful and I want noise Also let's01:37:50
just pop for01:37:53
again and here I can just use five what01:37:56
value I'm following over here01:37:59
Point here I will use01:38:02
75 something01:38:05
differ it's up to you you can just01:38:07
follow same value on all of them now you01:38:09
can have some01:38:11
randomization and I want different color01:38:14
also so I'll use pop01:38:18
color if I use Rambo here here it's01:38:21
already set to NH that's good thing this01:38:26
doesn't work I have to manually set this01:38:30
this time I will use this green01:38:47
different yep that's all let's check01:38:50
from camera01:39:07
and you can see we can we have multiple01:39:09
burst over here that's I don't want that01:39:13
so I'll just reduce01:39:15
it next I will talk about particle post01:39:20
processing now we will cat these and add01:39:22
some color but before that let's add01:39:29
Sparkles this thing is fine I will add01:39:32
one more merge over here and that's01:39:35
totally different so for Sparkles also I01:39:38
will use pop01:39:40
replicate and I want this from main01:39:43
points only so I'll just connect this01:39:45
and I name these Sparkle souls and here01:39:48
also I have to use the same one01:39:55
let's connect01:39:57
this and now let's01:40:01
play yep that's01:40:03
one and we have done this many times so01:40:06
we already know we need 10001:40:10
points and one by01:40:15
one the shape we need01:40:18
point we don't need noise01:40:21
I need less01:40:24
inheritance let's just increase this01:40:26
that's01:40:32
fine yeah and we will add drag also so01:40:34
I'll just copy01:40:37
this and paste this over01:40:40
here and now we can increase01:40:45
this yeah so I want to cover this area01:40:49
so I can just increase01:40:51
maybe 21 is01:40:54
fine01:40:55
yep maybe let's reduce it a bit01:41:03
yep yeah so I want render this so this01:41:07
is my source right I want to burst extra01:41:09
over here so that's how it will look01:41:11
cool one more time I need pop01:41:14
replicate and this time I won't connect01:41:18
this way here because it won't simulate01:41:20
I want to directly use01:41:25
this because whatever is that emited01:41:28
right I won't be using that I will01:41:30
directly use this bust which is that and01:41:33
we will have group these groups so let01:41:35
me just name these just Sparkles that's01:41:39
all and here also it's same oops not01:41:43
this01:41:48
100 one by one it's fine point point we01:41:51
will work on life but let's just set01:41:53
everything01:41:57
first yep and here also we will need01:42:02
drag and let's it pop color also so I'll01:42:06
just copy this and this01:42:10
time let's use some different color this01:42:13
thing cool everything is01:42:17
set press shift l01:42:29
so you can see that this thing is01:42:31
changed so I'll just reset over here to01:42:35
fix01:42:36
that yeah now I want this01:42:39
thing let me select camera01:42:45
again cool it's working so I have to set01:42:48
some value over here so let let me01:42:51
reduce count01:42:53
first and 100 is too much for that and I01:42:56
want less01:42:58
life that's first01:43:09
thing oops so I have done it not on this01:43:15
one that's fine I need to work on this01:43:18
thing so here I want 2001:43:21
and I need one by one that's01:43:35
fine let's give it uh blue color still01:43:40
not01:43:43
visible01:43:47
yeah so now life is also set here I will01:43:51
reduce these and I want to increase this01:43:55
it's not visible01:44:01
yet yep that's what I01:44:06
want01:44:11
see and we won't render those white01:44:14
points we will just render this01:44:19
blue01:44:32
it just start busting too quickly so01:44:34
I'll reduce01:44:36
this yeah now it's01:44:49
fine y y That's01:44:52
fine everything is set over01:44:56
here and one more thing what is this pr-01:44:59
solve so here also I'll explain this01:45:01
thing let me just duplicate this to01:45:04
explain you01:45:08
that and here I will use just both are01:45:13
same only so have this solver works01:45:15
first it will calculate this and after01:45:18
that it will calculate this so whatever01:45:20
you want to set01:45:22
before source and everything you can01:45:24
just connect this over it just one frame01:45:27
offset so if I connect this for here01:45:29
also everything will be same it will01:45:30
just offset let me show you let me reset01:45:34
see you have noticed01:45:36
difference yeah so this is pre-ol and01:45:40
this is postr just one frame01:45:44
difference so we don't so post Sol is01:45:49
fine01:45:51
and I want to cat this now let me delete01:45:54
delete everything press01:45:56
L I will use file01:46:01
cache and I still prefer this path so I01:46:05
can just clearly mention which file01:46:09
name dollar01:46:11
O dollar01:46:13
O yeah let me just cross check01:46:17
everything yep it's taking that and here01:46:19
I'll use particles01:46:22
V1 and01:46:25
load so it's set over01:46:28
here let's cast01:46:32
this so at the moment I have cast01:46:35
everything right and let me just check01:46:38
the data it's 333 MB that's fine but01:46:42
here I can just optimize this also if I01:46:44
M click I have lots of attributes so I01:46:46
can remove some of them and I can keep01:46:49
most useful only so how we can do that01:46:51
for now I'll just disable this and I01:46:53
will use attribute01:46:57
delete and I will just select delete01:47:00
non- selected so by default it will01:47:03
delete everything over here okay so01:47:05
let's start by so what we need over here01:47:07
so color is fine by default it won't01:47:10
delete position right so we will always01:47:12
have01:47:15
position I don't want age for now ID is01:47:19
most useful01:47:23
yeah so I have used01:47:31
three so first let's start by splitting01:47:34
this I want this thing over here let me01:47:36
use01:47:39
split so these are the groups I have01:47:42
created so this is just stream names and01:47:46
I can split them so first I need main01:47:49
trail01:47:52
do I have that yep so that's the one so01:47:56
we don't have burst01:47:58
anymore let me copy01:48:02
this split over01:48:04
here and I will use alt and01:48:09
copy and I want second ver01:48:15
Trail or this01:48:17
one I need just bus trail01:48:22
only yep that's also01:48:33
fine and third thing we already know01:48:36
second bu01:48:39
drill01:48:41
yep we have this01:48:43
thing fourth one is just01:48:47
Sparkles do we have that we have that01:48:51
now everything is separate and we can01:48:53
work01:48:55
on those01:49:00
things and what do we have this is just01:49:03
those01:49:04
points see which we don't need01:49:18
it now I I want to walk on the01:49:22
colors yes so I will just choose01:49:27
color and I can use enage over here so01:49:31
I'll just use RAM and01:49:34
enage so we know that NH requires two01:49:38
attributes which is age and life so let01:49:41
me just release them from here age and01:49:45
life I have those two so we we01:49:47
understood why we need age and life now01:49:50
now we know ID is most useful we have to01:49:52
always keep it velocity is most01:49:55
useful yeah so01:49:57
now but en is not working because that's01:50:01
hidden attribute and if you want to use01:50:04
it so you can just create one point01:50:07
triangle you don't have to do anything01:50:09
extra just use n capital that's just XYZ01:50:12
attribute and you can use use01:50:16
NH and here I can just mention capital n01:50:21
now it's working color attribute cannot01:50:23
use hidden attributes so you have to01:50:26
just create XYZ or something then you01:50:28
can just use over here yep that's01:50:31
working over here okay so here I need01:50:34
bright and here I need01:50:36
dark let me use or or else I can just01:50:39
switch this value also but let me go01:50:42
this way I need bright01:50:49
yellow01:50:52
five let me just use some01:50:55
orange and here also I'll just use some01:50:58
orange with some dark01:51:03
value yep that's01:51:09
fine and this thing we can keep here01:51:11
also01:51:13
oops so we can utilize01:51:16
everywhere that's one01:51:18
thing01:51:20
and what's happening over here I have01:51:22
multiple right and I want to split them01:51:25
maybe 50% I want this yellow color and01:51:29
50% I want something else let's use red01:51:32
color right so how do we split it01:51:35
remember we have used that wax where is01:51:39
it01:51:41
track yeah so we can use this here as01:51:43
well to split them out and01:51:46
here you can use pointer angle or you01:51:48
can just use at attribute adjust01:51:53
float and what I need over here is I01:51:56
want to split it I'll just create one01:51:58
attribute01:51:59
split and what I need I want to set01:52:03
attribute over here and01:52:07
random and random based on custom01:52:10
attribute which is ID over here so it01:52:13
will work on that so it will give me01:52:15
from 0 to one value and I have that01:52:17
randomized by ID custom attribute01:52:22
if I don't use this element number will01:52:23
be01:52:25
this point number and which we know it's01:52:29
not so useful when particles are01:52:32
dying yep so here also we can just use01:52:35
one more extra01:52:38
split let's just use split greater01:52:43
than5 it's split01:52:47
now oops wrong01:52:51
see and let me just color01:52:58
them I want red01:53:02
color please or maybe let's use01:53:06
bright oh it's not ramp over here so we01:53:09
have to use01:53:11
ramp I will use bright red in the01:53:16
middle and here I want bit dark red01:53:25
let's just use this just y let's much01:53:29
them01:53:41
both it's seem why same why it's not01:53:45
working and we need to understand these01:53:48
things over here so so what's happening01:53:50
at the moment everything is working it's01:53:52
correct let me just take a screenshot so01:53:54
we have these particles and we have IDE01:53:57
on that thing what we need over here is01:54:00
I need ID for this entire01:54:05
area one and two and what we have right01:54:09
now is individual points ID I don't want01:54:12
that that's not useful right so we can01:54:15
create that it's not that01:54:17
hard so remember we have this thing01:54:20
here and just one more thing everything01:54:22
is going straight right so it's right01:54:24
time to add pop Force here01:54:35
also and I can just use 10 over here and01:54:40
SW size also01:54:43
10 yep now we have some nice01:54:48
shape and I can increase this01:54:53
more yep that's01:54:57
working now let's back to the ID this is01:55:00
my main points and whatever we have over01:55:03
here so it will use01:55:06
that right and here I need to set some01:55:10
individual Point attribute over here and01:55:12
let me create that I will just use po01:55:16
angle I can just create any attribute I01:55:19
want main ID and I can just use at01:55:23
ID just Store Main ID and here also I01:55:27
had01:55:33
to here also I have to use that do we01:55:36
have main ID yes main ID let me copy01:55:43
this and paste this over01:55:46
here we need ID01:55:59
yep it's working01:56:03
now01:56:11
see let's give it some different color01:56:14
to identify01:56:18
that01:56:37
see and we can just keep this over here01:56:42
also and I can just copy this multiple01:56:46
time alt so so for each bust you can set01:56:51
your01:57:11
color yep and for last one I will prefer01:57:15
this01:57:18
thing yep let's merge01:57:21
these all of01:57:22
[Music]01:57:24
them it's01:57:28
done let me01:57:37
play this Trail looks bit longer so I'll01:57:40
just reduce01:57:42
it.4 and let me01:57:48
see01:57:55
y this green color is not working we01:57:57
need01:58:01
red we need red over01:58:07
here01:58:11
y dark red I'll just copy01:58:14
this and paste over01:58:18
here01:58:25
so you can see the01:58:38
difference yep so now we know which01:58:41
attribute we have used and groups and01:58:43
everything now let's just catch this01:58:45
again and see the01:58:47
difference so we have reduced C size01:58:50
also before it was Triple 3 now it's 19301:58:53
and that's the difference and we know01:58:56
that which attributes we need to use01:58:57
over01:59:01
here but here you know this looks too01:59:05
complicated you know I know it's simple01:59:07
that's splitting and everything so can01:59:09
we achieve this with just one node yes01:59:12
we can achieve that so next I will show01:59:15
you how we can achieve this just with01:59:17
one node attribute walk and let's see01:59:19
that01:59:21
next so we just need one node for now I01:59:27
will just set this over01:59:31
here and I will01:59:33
use point01:59:38
w I'll rame this Lo da over here so here01:59:42
also I have some options I can just say01:59:44
select group which group I want and01:59:48
everything here so let me just double01:59:56
click yes so this is what I have over01:59:59
here and I can just create everything so02:00:03
first let's start with this02:00:06
thing I have used this NH so here I02:00:09
don't have to do that it's fine and02:00:12
second one is this split which I have02:00:14
used02:00:16
main so we can just start with visualiz02:00:19
first I'll just start with this02:00:22
color what I need over here is02:00:27
ramp okay ramp needs some input over02:00:30
here right so what we have used02:00:34
here so we have used that NH Capital02:00:38
NH and that's what we need over here02:00:42
small nage and to call that attribute02:00:46
which attribute I'm talking about is02:00:48
this02:00:51
to call that attribute we have to use02:00:56
bind02:00:58
NH and what is that I have to check that02:01:01
I can just midle click over here age is02:01:05
float life is float energ is also02:01:10
float so let's connect02:01:13
that and where do I connect02:01:16
this to color over here02:01:20
see it's02:01:22
working and I will just copy02:01:27
this before that I'll just rename it02:01:30
first02:01:32
amp and I will paste over02:01:40
here02:01:48
nice02:01:51
and next what we have done over here is02:01:53
the split so let's work on that I want02:01:56
to split based on02:01:58
group how we can do that over02:02:06
here and for this two group I will need02:02:09
ramp also this is my second02:02:13
ramp and let me just keep it same only02:02:17
red02:02:23
yep I have second I'll keep it bit02:02:25
bright in between02:02:34
that yep that's02:02:39
fine to split based on group let me just02:02:43
copy this02:02:45
group and here I have to02:02:49
use group so I have one node in group02:02:54
and what we need over here is first it02:02:57
searching for file name I can just02:02:59
connect this second it needs this02:03:03
group which is this02:03:06
thing and third thing is02:03:11
pum this Prim that's also02:03:15
connected and let me just visualize it02:03:18
what we have over02:03:20
here so we can see some black and white02:03:24
this is one and this is zero so we can02:03:27
use this value to mix them both and mix02:03:31
we need mix so here I have mix color so02:03:34
I can just simply use mix also and I can02:03:37
just use this02:03:41
vector and I will use02:03:44
bias this is input one this is input two02:03:49
so I want02:03:53
this over02:03:56
here let's just visualize that02:04:01
yep see how simple it02:04:08
was and let's just not use for a moment02:04:12
what I need what here is I want to split02:04:15
this boat also and how we can do that02:04:18
now it's time to visualize that remember02:04:21
we have created a split attribute using02:04:23
this ID I'll copy this main ID and we02:04:27
know how to load02:04:31
it is it load or what is it let's just02:04:36
check id id is in it's integer so I we02:04:39
can set integer over here what we have02:04:42
done02:04:47
there I have set this initial and I have02:04:50
used02:04:51
randomization ID so here also I can just02:04:54
use02:04:55
randomization random and it will give me02:04:59
from 0 to one let's just visualize02:05:05
that02:05:12
see and I can see some ramp over here02:05:15
right so this can be 0.5 so what it will02:05:19
do it will just mix that value and I02:05:22
don't want to blend those colors I want02:05:25
to just keep zero or one no gradient in02:05:28
between that and how we can do that so02:05:30
for that I'll just use02:05:33
compare so it will give me Boolean value02:05:36
which is always zero or one and here I02:05:40
can just set greater02:05:43
than5 and what is this02:05:46
bullion it's this thing02:05:49
a02:05:55
split5 we can just use extra mix for02:06:02
here now I will connect this02:06:06
again and I can mix them02:06:11
both02:06:15
see and let me just clear it out it02:06:18
might be02:06:25
confusing so here I'm splitting based on02:06:28
the02:06:29
group and this is just main trail and02:06:34
inside main trail I'm splitting again02:06:37
using this02:06:42
value right so if I want to add any02:06:45
randomization and I can here connect02:06:47
this here also02:06:49
and I know it's bit you know this WS02:06:51
things are always complicated to02:06:54
understand but just try to practice02:06:55
these things you know how things are02:06:57
working so the more practice the more02:06:59
time you spend on this WAP and Wrangle02:07:01
the more perfect you will become with02:07:03
and trust me you can see this we are02:07:05
using so many notes over here with just02:07:08
one note it's working like magic and02:07:12
here there are lots of Advantage also we02:07:15
have and also I just want to clean this02:07:18
up I'll just go over02:07:30
here yep so I can just see this ramp02:07:34
only first and02:07:41
second yep same thing I want for that as02:07:47
well02:07:51
I will just copy this and paste over02:07:56
there and now I can connect them this02:08:00
way so it's up to you if you want to02:08:02
rename this in change color but I'm fine02:08:05
with that so I don't want to change02:08:07
anything and I will just connect this02:08:09
right02:08:12
away so that's fine and second here I02:08:16
want to make some changes in this area02:08:21
so what I can do I can just change a02:08:23
seed so I can add over here connect02:08:27
this and this is just add here I have02:08:30
another value also add constant so I'll02:08:33
connect that and I can just use02:08:36
different seed for this02:08:42
thing press shift02:08:45
s and you can organize these things02:08:54
and definitely you can utilize more02:08:56
group also here you just need to go over02:08:58
here and change add one more mix and02:09:01
connect over here so that way you can02:09:04
split but I'll just stop over here02:09:06
because I don't want to add different02:09:08
different color I will just use same02:09:10
color02:09:12
only02:09:17
yep02:09:21
and why this looks too different because02:09:23
of we have used this add if I don't use02:09:27
it it will follow the same color can you02:09:31
see and I think that's fine I don't want02:09:33
to relatedly change it so whatever we02:09:37
done that's fine let's just delete02:09:41
it it should follow same color02:09:47
only02:09:49
contrl B to organize things everything02:09:56
nicely02:09:59
yep and we don't need this anymore let's02:10:02
Del this press02:10:06
L out02:10:11
particles that's all now we will render02:10:16
this let's talk about now and we can02:10:19
just go over here and check02:10:22
stage so this is s stage and you can use02:10:26
this way or you can just set this over02:10:29
here as well you just need to use02:10:33
lops yeah so it's up to you whichever02:10:37
you prefer I will use this thing and I02:10:39
will just create quick mark control 202:10:44
and for this one I will use control 1 so02:10:46
I can just jump between that plus input02:10:49
I can just use S input and let me press02:10:53
one copy this press two paste over here02:10:58
and let me name this02:11:00
particles so we can just start rendering02:11:03
this fireworks immediately but let's02:11:06
start with something basic I'll just use02:11:10
grid and pop02:11:16
networ and I want to02:11:20
use not this I want to02:11:24
use Yep this02:11:27
thing I'll delete everything and just02:11:30
keep velocity and ID that's02:11:36
all let's go to02:11:38
Stage yep we have that02:11:42
now02:11:44
yes okay so how do we render this so if02:11:47
I go over here and I can just02:11:49
use Karma CPU and it will render it and02:11:54
I have third option is karma x02:11:59
view yeah so this is more faster way so02:12:02
we will talk about this kma XP02:12:05
only and I'll just hide this grade and02:12:08
let me just press D and I want dark02:12:11
background over02:12:12
here cool let me pin this so we can see02:12:16
some radius over here but if I check at02:12:20
viewport we don't have any radius right02:12:23
it's just tiny particles how it's taking02:12:26
a radius so by default if we don't02:12:28
provide P scale it will create P scale02:12:31
on its own and we don't want that so let02:12:34
me reduce some particle count 1002:12:39
times yep and here I can just use02:12:43
randomize attribute so this is the best02:12:46
one and and I can just select this here02:12:50
you can use Point triangle point w02:12:51
anything but I I prefer this thing over02:12:53
here Dimension is three it's not a02:12:55
vector it's float value and I will set02:12:58
ramp so it will give me from 0 to one02:13:02
and if I go to second option I have seed02:13:04
so which is ID and now let me see me02:13:09
press02:13:10
two yep and let me pin this so if you02:13:13
want to set define radius you can just02:13:16
set this thing so smaller I can just02:13:19
copy this divide this so you can02:13:24
see that's the magic so it's not heavy02:13:27
it's render time it will figure out the02:13:29
scale of this particle and if you just02:13:32
use copy to points and assign a sphere02:13:35
it will be too heavy for now sphere is02:13:37
fine but if you want to assign any other02:13:39
geometries box or something in that K02:13:42
you have to go through that heavy thing02:13:44
but if you want to just render round02:13:46
particles you can just by default you02:13:48
can render by setting a p scale so most02:13:50
useful parameter is p scale in particles02:13:53
by rendering it and second let's check02:13:56
out velocity we need motion blur also02:14:01
right let me set a motion blur how do we02:14:05
visualize motion blur over here so I can02:14:07
use02:14:11
Karma and I have two inputs can just02:14:14
select this one second one is just for02:14:16
additional render ver that's fine yep02:14:19
and here I have to just select02:14:22
XP and when I press this it will rerun02:14:26
everything now it's rendering this thing02:14:28
part over here and I have lots of02:14:30
parameter over02:14:31
here and you can just go to camera02:14:34
effect and first I want to turn this off02:14:37
because I don't want any depth of fill02:14:40
and interesting part is motion blood so02:14:43
here it's not taking any motion blood so02:14:45
you can just use velocity T so it's not02:14:49
visible right let me just increase value02:14:52
over here I'll just increase motion I02:14:55
can just increase it by 10 time so now02:15:00
you can see we have motion BL and let me02:15:03
just reset this is the motion blur we02:15:05
have so why I'm showing this motion blur02:15:07
because when we render fireworks it02:15:10
won't be visible in distance so that's02:15:12
why I want to talk about this so we have02:15:14
some parameters over here xrom and02:15:18
everything let's keep everything02:15:22
zero so some of these parameters will be02:15:25
utilized by camera geometri time sample02:15:27
and02:15:29
everything so you can turn this on if02:15:32
you don't use this it won't read it so02:15:34
you have to select velocity version02:15:37
that's one thing and now it's fine I'll02:15:39
just disable it and second thing I want02:15:42
to talk about02:15:44
is let me just copy02:15:46
this one more attribute which is Alpha02:15:50
you know everything is solid at the02:15:52
moment and I want some transparency so02:15:54
when I use Alpha so it's not visible at02:15:57
the02:16:00
moment so somehow it's not visible over02:16:03
here right so with xpu it's not working02:16:06
let me cross check with02:16:08
CPU so yep so with CPU you can see it's02:16:13
working and just don't worry you know we02:16:15
will create a xpu Shader so we will set02:16:19
attribute there and we will learn how to02:16:21
use direct attribute also so you don't02:16:24
need to relay if there is any technical02:16:26
issue or something then you can just02:16:28
create your own attribute just connect02:16:30
and use it through the shter also yep so02:16:33
that's all those two main thing I wanted02:16:34
to discuss and now let's go back to our02:16:37
example press02:16:40
one I will use it and again this it's02:16:44
CarX02:16:46
View let me press02:16:52
L and I will use this camera over here02:16:55
so I want to load it can just use camera02:16:58
same02:16:59
UT so it will load everything and here I02:17:02
have to set that02:17:07
camera yep we have02:17:10
that and I can increase that's too much02:17:14
let's reduce it it's in minus 4 I think02:17:17
05 will be fine02:17:22
yep I need thick P scale on this one02:17:25
I'll just again use white triangle and I02:17:28
want to use it on main trail let me use02:17:32
0102:17:33
yep and let me rename this set P02:17:37
scale copy this paste over02:17:41
here in this example we actually don't02:17:44
need a light I want to use materal X02:17:48
Shader so how do we add Shader over here02:17:51
we need over here is material library02:17:54
and let me just connect02:17:58
this material X Builder and I'll just02:18:02
name these02:18:05
particles and here also I have to select02:18:09
particles and on Geometry I had to02:18:12
assign it02:18:15
particles so this is my Shader name and02:18:17
and this is particle name so you have02:18:19
noticed that everything is white so02:18:21
let's see what's happening over here02:18:24
okay so I have some inputs output02:18:27
displacement okay so displacement that02:18:29
we don't need we can just straight away02:18:30
delete it and let's just select this02:18:32
what's happening over here so I have02:18:34
base color specular and everything is02:18:37
there how do I select base color you02:18:40
know that color that which I have02:18:43
set this CD02:18:46
value and how how do we read it to read02:18:49
it we have to02:18:51
utilize geometry color02:18:57
node and we can just go in straight02:19:00
select this so it will render that thing02:19:02
it will just read CD attribute only but02:19:04
if you have said something else so you02:19:06
can use this geometry property value so02:19:09
in here you can just call any02:19:12
attribute by default it won't read02:19:16
it right so we don't understand this CD02:19:19
value so what is the name of my02:19:21
attribute02:19:26
and for that we have to just select this02:19:29
and we have to go to this02:19:33
saries and it will create something over02:19:36
here and that's geometry spreadsheet we02:19:39
need and let me just02:19:41
see these are the attribute and name and02:19:43
everything I have and let me just check02:19:49
do we have yep so we have this display02:19:52
color okay so I have to write this02:19:55
display color02:19:56
now okay let me just type display02:20:02
color and let me check02:20:06
now now I have to again render02:20:10
it yep it's working I need dark02:20:13
[Music]02:20:16
background02:20:20
yep it's working but earlier if I type02:20:23
CD it was not working now it's02:20:27
working yep so these are the things that02:20:30
we need to check02:20:32
out and I can see that it's locked at02:20:35
the moment and I don't want that so at02:20:38
the moment we don't have light in the02:20:40
scene so by default it will create a02:20:43
light so I don't want to use this02:20:44
default light you know fireworks are02:20:46
always bright right so we have to use02:20:49
this color as a02:20:50
emission in this thing so if I connect02:20:53
this you will notice that it will become02:20:59
bright and let me just go to this02:21:04
emission press02:21:06
one and you can see we have some white02:21:09
tone also because of this let me keep it02:21:11
zero yep now it won't depend on light02:21:16
anymore02:21:20
yep that's all we need to do over here02:21:23
we can just set a size and again I will02:21:27
use motion02:21:30
blur it's not visible but we have to use02:21:32
it let me just render few02:21:36
frames so you can just go over here02:21:39
select and render template and that's02:21:41
too fast it's taking 4 seconds only to02:21:43
render02:21:45
it cool and here I can just work on some02:21:48
optimization I can just reduce02:21:51
it the02:21:53
samples and there is some noise also so02:21:56
I can use filter and I will use Intel so02:22:00
this is also bit sharp you can see the02:22:02
difference so I'll go with this02:22:05
one and let's just compare see we don't02:22:08
have noise02:22:09
anymore that's cool and next video I'll02:22:12
talk about technical02:22:14
U yep so let's talk about technical is02:22:18
we need to understand what exactly we02:22:20
need first we need RGB so in comp I want02:22:24
control to select these things right so02:22:28
I can just select this random right so02:22:30
this can be red green blue so I can just02:22:33
color them differently so that's fun02:22:35
thing second what I need is selection02:22:38
pass what is selection pass so this is02:22:42
one and bursting is second right and we02:22:45
have sparkle also that thing so we can02:22:48
just assign them RGB color on this thing02:22:51
as well but it will be selection for02:22:52
selection and third we need gradient so02:22:56
we have to keep this hot core and it02:22:58
will gradually give us some ramp so that02:23:01
also we need so that's third thing and02:23:03
fourth one is H so we need ramp I want02:23:07
this hot area and we should gradually so02:23:09
I want this core area right so that we02:23:11
will do let's just do one by one let's02:23:14
start with RGB so whatever you want to02:23:17
create you have to create at sop level02:23:20
so for that also I will use and you02:23:23
can still utilize this WAP but just for02:23:26
better workflow I will use another02:23:31
W and I'll just name it02:23:35
a yep so here we need RGB and I cannot02:23:40
utilize this ID right so I have to use02:23:42
that let me middle click main ID02:23:47
so let me use bind to call02:23:52
that main ID and it's integer cool and02:23:57
after that I need02:24:01
random and let me just visualize this02:24:04
yep it's02:24:08
working and I will02:24:11
assign02:24:14
color RGB ramp02:24:21
and this is zero value and this is one02:24:23
value so I can just use02:24:27
that in middle I want02:24:33
green and I don't want that gradient so02:24:36
I'll use constant02:24:40
value02:24:45
yep02:24:49
yep in compositing I can utilize any02:24:52
color I02:24:54
want and you can see these both are same02:24:56
you I don't want that so I'll just add a02:25:00
seed over here let me add constant and I02:25:04
you can02:25:06
see yep so that's how you can just see02:25:09
like02:25:10
that so if I want to change color of02:25:13
this I can select that color in the comp02:25:15
and change the color02:25:18
and now let's render it so don't just02:25:21
export this into a color so we have to02:25:24
create bind export for that also so I'll02:25:28
use bind export and you can see this is02:25:30
for import and this is for export so it02:25:32
will create02:25:35
attribute and I'll use02:25:38
RGB02:25:40
PR and just make sure that you don't02:25:43
copy this name again and again right so02:25:45
if you use RGB over here and don't use02:25:48
RGB here because it will create an issue02:25:51
so always just keep different name and02:25:54
make sure you have that RGB over02:25:57
here nice so let's just render it02:26:01
now so I'll just go over here and how do02:26:04
I read that eov I'll have to go to this02:26:07
image output eovs and I have lots of02:26:10
parameter over here so what I need to do02:26:12
is extra verse so let me just use h R GB02:26:18
that's all and it's a vector because02:26:20
it's a three color and if I added this02:26:24
name it won't work we have to use Source02:26:27
name also this is the main one just02:26:30
always change this both and now let me02:26:33
just render to check aov we have to go02:26:36
here and render oh it's blank and let me02:26:41
just close why it's blank because02:26:43
whatever EO you want to render it should02:26:46
go through this material first and I02:26:48
need AOE node over here so it's not02:26:51
there why because we are using this mul02:26:55
library and somehow it's same Vex02:26:59
Builder only but it's not working02:27:00
properly over here and this is02:27:04
just some technical issue we just need02:27:08
to use material network over here and we02:27:11
can use use Karma material02:27:15
Builder and there is a little difference02:27:17
in here right so you can see that this02:27:19
is02:27:24
different and we have some material02:27:26
properties also over here and if I type02:27:30
AO over here that we have that AO and I02:27:33
want to utilize this02:27:35
thing so it might be a technical issue02:27:38
so I'll just use02:27:40
copy and paste over here and I'll just02:27:44
name the same material and space space02:27:47
and I'll copy this name over02:27:50
here02:27:52
yep let's just make some changes again I02:27:56
want02:27:57
color geometry color in02:28:02
amission and we have to keep this zero02:28:05
and emission02:28:07
one till here it's fine and we have AO02:28:11
is also oops it's02:28:14
wrong yeah let me just move02:28:19
it cool so we need to load that AO so02:28:22
I'll use geometry property value over02:28:25
here and it's a02:28:27
RGB RGB color let me connect02:28:32
this this thing will rename our AO so02:28:35
make sure that you use this RGB here as02:28:38
well so you can see output and you have02:28:40
to connect this02:28:42
here and it's a vector AO and this thing02:28:47
is also Vector so you can see yep and02:28:50
now let me go outside and add everything02:28:54
is set over here so let me just render02:28:58
it yep now I have that AO so here I can02:29:02
just select that and cross check02:29:04
everything is working properly fine so02:29:07
that's all it was this simple and I can02:29:10
delete this02:29:11
thing and let me stop and let me work on02:29:14
other a as well now02:29:20
and next I need AJ so I will use02:29:26
bind02:29:30
NH and I can export this so I want02:29:36
use just age over here so I have to02:29:38
write age and capital02:29:41
P and in between that I will use ramp02:29:48
so this will be02:29:49
AG02:29:54
RAM and let's just visualize02:30:03
this yes so here also I have to set02:30:06
range and this is black so I need02:30:15
red02:30:21
blue yep so you can see that we have02:30:23
that a also in02:30:26
here and we can use that to Bright this02:30:31
tip that's02:30:39
nice second a is radius right so I can02:30:44
see that what I need over here is radius02:30:48
I need bright in here and it should dark02:30:51
so for that we have02:30:54
to store that02:30:59
NH right so this thing is fine after02:31:02
this you know this thing also has a02:31:04
separate normal AVS like I want to carry02:31:07
forward that same a in all over this and02:31:12
let me do that first so you will02:31:14
understand so I'll just create02:31:17
create capital n h is equal to02:31:22
NH02:31:25
yes and let me just bypass this for a02:31:27
moment and I have02:31:31
to it's not visible over here so let me02:31:34
just reset02:31:45
it02:31:53
yeah so let me just use something02:31:55
else Norm02:31:59
H and let me just reset02:32:02
this okay I got02:32:05
it so here this thing is still not burst02:32:10
yet right so that's why it's not visible02:32:14
so after this thing now we have that let02:32:18
me show02:32:20
you NM age so earlier we were right it02:32:23
was working but it's not bust that's why02:32:25
so these are the things so you need to02:32:27
take care of also it's good thing that02:32:29
we face this issue and we have solved it02:32:32
yep and here I will use02:32:38
bind Norm age it's a vector again I have02:32:43
to use02:32:45
ramp02:32:48
it's a radius02:32:52
ramp and let me just straight away02:32:54
connect so to check is it02:33:01
working yep it's02:33:08
working here also I will use the same02:33:11
thing let me02:33:15
paste02:33:20
and I can just make some02:33:23
changes like this thing over here little02:33:27
bit02:33:31
bright yep so I have this set AO so I'll02:33:35
also rename02:33:37
this bind02:33:43
export and this is radius02:33:48
and fourth one I need is selection and02:33:51
how do we select that so we know we have02:33:53
to use group for02:33:59
that let's just connect this02:34:06
and pum also and here what we02:34:12
need stream main02:34:15
trail02:34:18
just make sure type things very clear02:34:21
and here I will use02:34:28
mix yep so I need red color over here so02:34:32
I can use02:34:34
constant so02:34:36
Vector this things will02:34:38
be red02:34:42
color and I'll just copy02:34:45
this and here I can just use bus02:34:50
trail and again I will use02:34:58
mix and here also I can just add some02:35:00
value me02:35:02
copy02:35:06
constant02:35:15
yep02:35:21
so it's not using this bus trail02:35:24
maybe so it's a b capital over here so02:35:28
those are the thing make sure to you02:35:30
type things very clear yep and I will02:35:34
just swap02:35:39
it02:35:44
yeah02:35:51
and here you don't have to worry about02:35:52
those things so we can just delete those02:35:56
particle I don't want those things right02:35:58
I'll just use bus trail main trail and02:36:03
second bus02:36:04
trail rest of the things are Del02:36:11
see and sparkles are these yep02:36:16
see now those things are02:36:25
deleted let me just cross check do I02:36:28
have main tril over here yep now it's02:36:30
visible earlier it was not and after02:36:33
that I need this bus trail this is also02:36:37
visible and Sparkle I need and second02:36:41
trade I need02:36:44
yep02:36:48
so you can see here that we can see some02:36:51
issue sometime it's reading sometime02:36:53
it's not you02:36:57
know so it's fine so you can do this02:37:00
before cashier so you won't face any02:37:04
issue02:37:05
trails and let me just catch02:37:10
everything yeah so now we shouldn't face02:37:14
that issue see it's working02:37:17
and we have everything over02:37:23
here so you name this attribute anything02:37:26
you want I will use cell as02:37:29
selection yep and let me02:37:34
just and we have to remember these02:37:36
things HP radius and cell let me press02:37:41
two we have to use same thing let me02:37:46
just use geometry value over02:37:49
here first is02:37:52
HP we just copy make sure it's a02:37:56
vector it's a02:38:02
radius mind oops let me just copy02:38:06
this and02:38:09
sell s again it's a vector vector this02:38:15
this thing is also Vector02:38:18
yep I will use kma02:38:21
a let me just connect this and avoid02:38:26
naming this age you know something else02:38:29
we can use so I will use age02:38:36
ramp connect this and next02:38:41
is radius so we don't have radius so02:38:44
still you can just use radius r02:38:50
ramp and cell we don't have cell so we02:38:53
can just use02:38:56
sell02:39:01
yep let me just create that one by one02:39:04
so I will be adding more02:39:07
three so let's go one by one first is AG02:39:12
ramp and it's a Rector02:39:16
H02:39:19
ramp second is02:39:21
radius02:39:24
ramp so02:39:26
Vector let me just copy02:39:30
paste and third is02:39:32
cell simple02:39:35
one02:39:37
three and sell02:39:44
cool02:39:46
yeah so these things are visible on this02:39:48
Frame so I'll just render this Frame02:39:50
only let's just cross check that all a02:39:53
are rendering or not so if there is any02:39:56
issue that we will02:40:01
fix yep it's let me check RGV is working02:40:06
age ramp is also02:40:08
working yep radius is also working let02:40:10
me just02:40:14
check02:40:17
cell is are02:40:19
working red green blue so I don't want02:40:23
this in the cell right so we have an02:40:25
issue let me fix that02:40:30
quickly let's just check02:40:34
cell yep so here we can just use02:40:43
Sparkles yep02:40:51
because it was reading this as a02:40:53
separate thing and I don't want that and02:40:55
I have clear separation that's what and02:40:58
that's02:40:59
fine let me disconnect02:41:05
this so next we will cross check02:41:07
everything and render this02:41:10
sequence yes so let's finally render02:41:13
this and here I'll check some02:41:16
parameter I want render and dollar W so02:41:20
it can create that folder okay sampling02:41:23
is also fine so here I don't have to02:41:26
change anything and that's really simple02:41:29
example that's02:41:31
why this is also fine Advance02:41:35
deep filter this is working well e is02:41:39
also working well yep so now only one02:41:43
thing is missing is Alpha02:41:46
Al we have not utilized it and sometimes02:41:50
Alpha is most useful right so let's just02:41:53
use Alpha02:41:55
so where we need Alpha to dissipate this02:41:59
right so I want to dissipate this Trail02:42:01
in the02:42:02
end and let's see how we can do02:42:07
that that's fine I will utilize this02:42:11
thing and I want to use ramp and this02:42:14
thing will be02:42:17
Alpha RAM and Alpha A is capital so we02:42:21
have to use B02:42:28
export a capital02:42:31
Alpha yep and I want02:42:36
float let's connect this and nothing is02:42:39
visible over here so I scroll02:42:41
down yep now it's visible so where is it02:42:45
working it's it's not working correctly02:42:48
so I have to just use this and this02:42:51
thing over here yep now you can see02:42:56
that see it's change a lot right which02:43:00
one it looks better this thing this one02:43:02
looks more better we have that cran02:43:06
tram this thing can be done in comp02:43:09
because we have that age ramp right but02:43:11
fine using this here sometimes you may02:43:13
need transparency in com that's why I'm02:43:15
showing you this thing okay so let's use02:43:18
this02:43:23
now and how do we use that here like02:43:27
color it won't use that so we have to02:43:29
call that attribute let me use geometry02:43:31
value so I don't know what I have to02:43:33
write over here so let me just check02:43:35
that02:43:36
first I will select let me scroll down02:43:40
do I have anything related to02:43:42
Alpha yes so it's oppacity is there02:43:46
right so I have to type02:43:48
display opacity and where do I connect02:43:52
this I have to connect this over here02:43:55
opacity let me02:43:57
see is it working or not I'm not sure02:44:00
let me render this02:44:03
XP me pin02:44:07
these okay so I have to cross check this02:44:09
is it working or02:44:12
not yep it's working02:44:18
everything is set now let me press02:44:21
L I don't want this02:44:23
Alpha set P scale everything is set02:44:31
properly oops02:44:33
wrong yep and I want to increase count02:44:36
over here so let me just02:44:38
go 2,500 let's use 3,000 over here and02:44:43
bursting also we we can 100 is fine but02:44:47
I want to increase into the trailing so02:44:49
I will use this02:44:53
1,000 busting is fine I want increase02:44:56
this trade02:45:03
1,000 and this thing is fine yep so what02:45:07
I need to do over here I don't want to02:45:09
cash this and after that launch right so02:45:11
I want to use a sequence over here and02:45:13
let me just build it first02:45:15
I'll use02:45:18
two drop Network and I can use fetch02:45:21
over02:45:22
here fetch this is just cach and second02:45:28
thing02:45:29
oops and second thing is render and let02:45:33
me connect02:45:34
them so I have to read cach over here me02:45:38
press one and what I need to use over02:45:41
here is render let me press two02:45:45
and paste over02:45:47
here yeah and second thing is render so02:45:51
I can just directly call this02:45:57
thing yep and I have to rename this now02:46:01
particles version02:46:03
one and let's just cross check02:46:06
everything yeah yeah everything is02:46:08
perfect and let me resolution is also02:46:12
fine that's a surrender to double CR02:46:15
everything before02:46:17
rendering RGB is working age is working02:46:21
radius is working cell is02:46:25
working I don't want02:46:29
this02:46:33
yeah let's close this thing yep02:46:36
everything is02:46:39
fine that's because I have stopped that02:46:41
in02:46:44
between02:46:46
and here I have to use range over here02:46:49
it's from 1 to02:46:51
240 and it will utilize that range so I02:46:55
have to click this and node by node and02:46:59
I can just render this so first it will02:47:02
cach everything and after that it will02:47:03
render yep so next we will work on02:47:07
comp yep renders are done so let's02:47:10
compete to read our renders we have to02:47:12
press R and here we can just paste02:47:15
render path over here and let's read it02:47:19
and to visualize this press one so it02:47:22
will connect so this is viewer right02:47:24
whatever you connect over here it will02:47:26
be visualized and let's play02:47:30
this yep so this is the render we have02:47:34
and we will work on it before that let's02:47:37
just check this is the properties that02:47:39
we have this is background renderer02:47:41
that's not02:47:43
useful now let's set project file First02:47:47
Press s and this is Project settings we02:47:50
have and here these are the parameter02:47:52
limit if you keep this 10 it will show02:47:55
this parameter over here so I want just02:47:57
one parameter only meaning one node only02:48:00
so it will visualize one setting at a02:48:01
time here I have to set this it's02:48:04
correctly set and lock frame R is also02:48:06
correct but resolution we need to change02:48:09
it to full HD and that's all yep now I02:48:12
can just select this everything is02:48:14
loading properly over here good and I02:48:17
want to check aovs where are my aovs to02:48:20
check aovs we have to use this layer02:48:23
contact02:48:24
sheet and if I connect over02:48:28
here and visualize that we have02:48:31
everything and let me just check over02:48:33
here so show layer names and you can set02:48:36
resolution02:48:37
also one02:48:40
80 and here you can just change things02:48:44
or keep it automated this is my color02:48:49
value and this is my RGB let me just02:48:51
cross check yep that's perfect age RM is02:48:55
also fine radius is also02:49:00
fine and cell is also02:49:04
correct cool now let's work on it first02:49:07
let's start with02:49:09
grid you can press G it will give this02:49:13
grid and here here you have control to02:49:16
increase the brightness of this thing02:49:19
and this is one node we have other node02:49:21
also we have this CC where you have more02:49:24
control but to keep this simple we can02:49:27
just use Gade that's simple node over02:49:30
here with less parameter02:49:32
especially cool so which node I want02:49:35
first I will work on radius I need02:49:38
brightness over here in the middle right02:49:40
so let's do that first and here I can02:49:43
just create this null02:49:45
node and I can just use02:49:48
Shuffle to extract02:49:51
that a so let's just use02:49:55
Shuffle and what I need over here I can02:49:58
just select that I need02:50:01
radius yep so that's02:50:12
right so how do we use it02:50:15
so what's happening over here I want to02:50:18
just work on this radius part only right02:50:21
but here this also counted in red02:50:24
area right so I need red part bright and02:50:29
here also you can see that we have red02:50:31
color so I have to subtract it so I will02:50:34
use one more Shuffle over02:50:38
here and I can just connect this here02:50:42
only and I will use cell02:50:46
which one I want I want to work on is02:50:48
this thing this02:50:50
bust okay so I will use02:50:57
grid and I will just connect this to the02:51:00
mask and I want to use just Green Layer02:51:04
only so I can02:51:06
select use this rgba color green and I02:51:10
can just keep it this way let me just02:51:13
visualize that okay so it's not working02:51:15
properly so we have to use int now we02:51:19
have that everything is removed now and02:51:22
we have those things only which is02:51:24
correct and what's happening over here02:51:28
is it will work on this just RGB only02:51:31
and I want to work on all aovs so we can02:51:34
just select all and one more thing it's02:51:38
not clearly selected everything right so02:51:40
here you can just go and02:51:43
increase the gain so you can just02:51:46
brighten it02:51:49
up because sometimes this value is not02:51:52
enough to mask this right so you can see02:51:54
that before we have some gradient right02:51:57
over here and it will just make it clean02:52:02
that's what we02:52:03
want now this thing is perfect and it02:52:06
should work on that one cool now I will02:52:09
select over02:52:11
here so in The Mask I have all other a02:52:15
also so you can just directly call this02:52:17
value but here just to make things02:52:19
simple and you can visualize things also02:52:21
so I'll just use this color which color02:52:24
I want to make bright is02:52:25
red which this one and let's just check02:52:29
let me increase by 10 times02:52:35
see before it williz like this and now02:52:40
this thing and we can keep five only02:52:43
that's fine02:52:46
that's one02:52:47
thing it's working02:52:53
properly see this is02:52:57
bright02:53:05
right next again I will use02:53:09
grid and I will use Shuffle over02:53:13
here02:53:16
this time I want to use AG02:53:20
Ram so whatever is there on the tip I02:53:23
want to make make it bright so if I02:53:25
press R over here so you can02:53:28
see these are the tips and I have to02:53:31
press a two times to just use RCB red a02:53:36
do two times and this also I can just02:53:38
connect over02:53:40
here just to keep it clean I can here I02:53:44
can just02:53:46
select red value and I can increase02:53:50
it five times or let's increase it by02:53:54
three times that's02:53:56
fine yep so now you can see that we have02:53:59
some nice ramp over here you02:54:03
know this was flat and now you have nice02:54:08
core value over02:54:11
here see the difference02:54:15
and here you can just use two also to02:54:17
compare it press two you can press 1 202:54:21
one two now that's good and third thing02:54:24
I have two color only you know that02:54:26
looks too boring at the moment and I02:54:28
want to change the color so for that02:54:30
thing I will use shift so H shift I can02:54:34
just connect this and I can just rotate02:54:37
this value so it will give me other02:54:40
colors as well and remember that RGB I02:54:43
have created so I can use Shuffle so02:54:46
this time I don't have to use02:54:48
Shuffle I can just directly call that02:54:51
value don't use this thing because I02:54:54
have used gradient and I have masked it02:54:55
out and I have removed all CH Chanel02:54:58
over here let me just show you what I02:54:59
mean by so in this thing everything is02:55:03
visible here here also same thing but02:55:07
here we have remove something let me02:55:10
show you02:55:13
see see this thing is removed so that's02:55:16
why but here it's is changed even if I02:55:19
use Shuffle and02:55:21
everything yeah so make sure you02:55:23
carefully use this all channel so it02:55:25
will work on all Channel over here at02:55:28
one02:55:29
thing yeah and I want which value I want02:55:32
to use so here I cannot just clearly02:55:34
visualize that so I can use this also to02:55:37
visualize that but let me just use02:55:39
contact sheet over here to visualize02:55:43
that oh let me contrl Z control Z I have02:55:48
that where is my RGB okay so which color02:55:51
I want to change over here02:55:55
is I think I can utilize02:55:59
blue so here I will use RGB02:56:07
blue and invert02:56:10
it it will no invert it won't work okay02:56:14
that's fine and again we have to use02:56:16
this you know that gradient thing I have02:56:18
discussed so this time I can just use02:56:21
all and press 10 so now it will clearly02:56:25
mask that area earlier it was using that02:56:28
gradian02:56:30
see okay now we can just change the02:56:32
color whichever color you02:56:36
want yeah blue is also fine with some02:56:41
depth we have over here02:56:47
yeah this looks02:56:53
fine see how easily we have changed the02:56:56
color you know if you render everything02:56:59
without aovs then you have to reender to02:57:01
change the color and that doesn't make02:57:04
sense and just for full screen you can02:57:07
press space bar to R make a full screen02:57:11
over02:57:13
here02:57:14
right so we have nice color range also02:57:17
over here that's02:57:21
cool and next thing I will work on okay02:57:25
now I cannot utilize this anymore but I02:57:27
can just shift it and one more Shuffle I02:57:29
can put over02:57:32
here to just visualize that cell pass02:57:37
again and this time I want to use this02:57:41
Sparkles these things and I want to to02:57:44
make it bright in fact I can utilize02:57:46
because I have to again use that02:57:48
gradient right so I'll just again use02:57:51
grade over here and connect this this02:57:54
time I need RGB02:57:57
blue and let me just increase it little02:58:00
bit or two times it's totally02:58:04
fine02:58:06
yep beautiful everything is set now you02:58:09
can see that these Sparkles are more02:58:11
visible02:58:12
now02:58:15
and just maintain this clean node02:58:17
workflow you know that this is very02:58:19
clear that we have said everything02:58:22
properly and02:58:25
fine that's good thing over here and02:58:28
next I want to use you know one of my02:58:30
favorite node which is02:58:33
glow and let's just use02:58:36
that how glow Works oops it's wrong Noe02:58:40
how glow works it just creates some02:58:43
outer layer but in production you know02:58:45
we don't use this glow there is some02:58:47
nice plugin which provides really nice02:58:49
glow you know the reason is because it02:58:51
gives this you know hard line over here02:58:53
and you have to work on it to get those02:58:55
nice ramp gradient ramp over here and we02:58:58
can do that but doesn't look realistic02:59:01
the plugin glows give really nice output02:59:04
and nice exponential glow right where we02:59:06
need it but we don't I don't want to use02:59:08
any plug-in over here so I will show you02:59:10
how to use this for now I will use this02:59:12
glow for something else and let me just02:59:14
talk about this02:59:16
parameter and this is the size we have02:59:19
and this is the brightness we have these02:59:23
are the two major parameter we have over02:59:25
here so size I'm not going to work on02:59:28
that I will work on this02:59:31
brightness so let me just use one02:59:34
brightness only and we have one02:59:36
interesting note over here is this02:59:39
saturation and if I reduce saturation02:59:41
you will notice that a bright color here02:59:44
so what we can do over here so you can02:59:46
just use this tolerance how tolerance02:59:48
work if I increase it you will see02:59:51
that we are getting02:59:55
that in the middle of that that's what I02:59:58
want so tolerance basically use that02:59:59
ramp wherever we have bright value it03:00:02
will add gloth there only and that's03:00:04
what I'm looking for so here I can just03:00:06
use03:00:08
six and let's see the difference can you03:00:11
see we have nice brightness in the core03:00:14
and it's really useful and I always use03:00:17
this to add a core see how nice it is03:00:22
and whatever we have changed over here03:00:24
and whatever we have used over here it03:00:26
will definitely work on that03:00:28
thing and let me just show you that03:00:31
without this see huge difference right03:00:36
that's03:00:40
why so you can increase the brightness03:00:43
point1 one it's up to you and saturation03:00:45
also I don't want to reduce that much so03:00:47
I can just keep some03:00:53
saturation otherwise it will be too flat03:00:55
and I don't want03:00:59
that that's03:01:04
nice and I want bit brightness in this03:01:07
area so let me just check which one is03:01:11
the03:01:12
cell this one is the cell okay so I'll03:01:15
just add one more grid over here and03:01:17
I'll just connect this and I want to use03:01:21
red03:01:23
Channel and I want little bit brightness03:01:26
yes because this is this should be bit03:01:30
brighter let me cross check03:01:37
yep03:01:41
yep nice03:01:44
cool so now we will add range glow and03:01:48
range glow is bit simple also so I will03:01:52
use multiple glow over here and let's03:01:54
just use03:01:55
glow I'll just use03:01:57
some connect over03:02:00
here stop so let's just increase this I03:02:05
want bright range03:02:07
first and let's just reduce03:02:11
it that's by it should visible that03:02:16
much see it's there but it's not clearly03:02:20
visible you can see the03:02:22
difference me just skip it one for03:02:26
now and let me use second03:02:29
glow this time I will use half of03:02:33
this and to merge them I will use plus03:02:36
merge this03:02:42
time03:02:45
so we can see it so if I use Simple03:02:46
merge it won't merge03:02:49
properly you can see the difference03:02:52
right so it will just screen them and03:02:55
merge them03:02:57
properly yep that's nice I want 200 so03:03:02
you know just divide that value by half03:03:05
now use 10003:03:10
now let03:03:12
me03:03:14
multiple glow over here and just use03:03:23
5003:03:26
25 10 let's just connect all of03:03:39
them yes now see the03:03:42
difference03:03:46
can you see we have really nice glow03:03:50
range and that's too bright you know03:03:52
that's too bright so we have to reduce03:03:53
it and one more thing I want to discuss03:03:56
is you can just use only effect over03:03:58
here and let me just show you how thing03:04:01
work so if you turn this on you don't03:04:03
have that and while using this if I03:04:06
press if I check Alpha that Alpha is not03:04:08
there right so you have to work on Alpha03:04:10
also so now you have glow Alpha03:04:14
so always just double cross check these03:04:15
things yes let's just do that over here03:04:18
as03:04:19
well03:04:21
effect Alpha must be03:04:28
there this creates an issue when you03:04:31
export PNG make sure it's always03:04:37
there yeah so now we don't have that03:04:40
core so you can just always add core03:04:42
value03:04:44
first this03:04:54
here yep so now we can just reduce it by03:05:01
two03:05:03
503:05:06
75 one is03:05:10
fine03:05:12
yep03:05:22
still the brightness is too much right03:05:24
so I have to reduce it overall let me03:05:27
just use03:05:28
zero03:05:30
zero for now and I will just increase03:05:36
it is this glow fine yep it's fine so I03:05:39
can increase03:05:41
this so this is still artistic choice03:05:44
that you can use this also but I want to03:05:47
use this that's03:05:50
fine yes so this is the range we have to03:05:54
mention it's clearly visible but it's03:05:57
there this will be supporting03:06:05
element yeah I want one more03:06:09
glow over here and this time I'll just03:06:12
use two03:06:15
and let me just connect03:06:21
this see without03:06:24
this without03:06:29
this now we have more crisp03:06:42
output03:06:46
yep that's all we can just make changes03:06:50
so but if you have plug-in glow you03:06:52
don't have to work hard on this thing03:06:54
see when it burst we have nice bright03:06:57
light but yeah have some reference to03:07:00
you know you can match this glow also if03:07:03
you have reference right there you know03:07:05
how to change things how to play around03:07:07
with the glow so those are the things03:07:09
you will mostly spend time03:07:12
on03:07:13
and yeah work on comp because as at FX03:07:16
artist you should know this comp how03:07:18
things work before passing it to the03:07:21
department like compositing you have to03:07:23
cross check yourself that you do have03:07:26
everything a properly and you have to03:07:28
make sure everything is working properly03:07:30
yep everything is just03:07:34
perfect cool I'll just render it03:07:37
now so this time I'll use03:07:42
right03:07:45
and I will let me set a path over03:07:47
here this03:07:49
is my new03:07:56
cender and just use version one and just03:08:01
render and here I have to use this for H03:08:05
just for frame right in Hy we use dollar03:08:08
F here I have to use this hash and I03:08:11
will use jpg03:08:14
and here I have to increase this03:08:16
quality and let's use create directories03:08:19
because I have not created this folder03:08:21
over here that's why and you don't have03:08:23
to change anything just press render03:08:25
make sure you select this Frame properly03:08:27
and03:08:29
render cool next we will review03:08:35
this Yep this looks cool and we can03:08:39
definitely enhance this and this example03:08:41
is just to understand and the particle03:08:44
approach that how things work out right03:08:46
and we also learned that how we can03:08:48
change color post rendering as well03:08:51
inside the03:08:52
compositing and you can definitely03:08:54
follow some one of my favorite website03:08:56
is action VFX so you can just check this03:08:58
so we have the Sparkles you know the03:09:01
different different color also we have03:09:04
it has some wind in this03:09:07
direction yep so you can just check this03:09:09
out there are lots of reference we have03:09:12
over here03:09:14
you can follow one of03:09:16

timeDescription:
To Support me, you can purchase this tutorial from the following link. https://vfxmagic.gumroad.com/l/particles1 CGCircuit: https://bit.ly/471nlHi Welcome to the 'Introduction to Particles' tutorial. In this course, we will create fireworks from scratch, starting with the basics of particle movement. We'll delve into controlling particle motion and their speed. Along the way, we will explore key attributes and learn how to use them to burst particles effectively. Once we have created a decent particle setup, we'll focus on look development, demonstrating how various attributes can be used to control color post-simulation. We will also consolidate the work of 10 nodes into one attribute, showcasing the advantages of using the Attribute VOP. Furthermore, we will explore Houdini 20's Karma XPU, setting up and executing renders, and even rendering technical AOVs for more control in compositing. Once rendering is complete, we'll move to NUKE for final compositing. Here, we'll learn how to utilize all technical AOVs to enhance the final look. Check out this new course on particles to learn the basics and more about particle systems. . . .
