hello everybody00:00:05
and welcome to the wednesday night00:00:10
modeling stream00:00:13
internet seems to be working pretty well00:00:14
today so i'm your streamer brian bentley00:00:17
this is the modeling stream for00:00:19
cgspectrum.com for all your modeling00:00:21
needs go to cgspectrum.com00:00:24
3d dash modeling00:00:27
uh man what are we doing today our wing00:00:31
is coming along i'm super super stoked00:00:34
uh so today hopefully hopefully we'll be00:00:37
getting into a little bit of texturing00:00:39
for00:00:40
for our feathers so setting up some00:00:42
procedural texturing00:00:45
to build out this feather so basically00:00:46
we can mimic the look of what we have00:00:48
here00:00:49
like these super super heavy these crazy00:00:51
heavy feathers that we have we have00:00:53
every single ridge00:00:54
every single kind of like like detail00:00:58
um you know expressed here but we want00:01:02
to do that in a texture00:01:03
right because we only want to uh00:01:06
we want this to be as light as possible00:01:08
because i'm thinking about00:01:09
possibly doing this in a uh in a game00:01:12
engine00:01:13
um so either uh who knows who knows00:01:16
maybe maybe00:01:17
uh probably unreal engine um because00:01:19
that seems to be the new hotness00:01:20
uh maybe uh i've been looking around00:01:23
i've been looking at a uh00:01:26
marmoset tool bag the the the latest00:01:29
edition they did looks00:01:30
really really powerful like it's really00:01:31
coming into its own so we'll see we'll00:01:33
see we have still have a lot to go so we00:01:35
have the wings00:01:36
we have the actual character to texture00:01:38
we have00:01:39
um i think the next thing i'm going to00:01:40
work on is her talons and her feet00:01:42
because they have like those cool like00:01:44
uh lizard kind of scales on them with00:01:46
the claws and little bumpy stuff00:01:48
so that can we can also do that but00:01:50
that's putting the cart before the horse00:01:52
um what i really want to do is is get00:01:55
this wing done this the whole wing00:01:57
is like this whole project is like six00:01:59
different projects all in one so00:02:01
uh so we'll just kind of keep going and00:02:03
keep going until00:02:04
until i run on steam or until you guys00:02:06
want me to do something else uh00:02:08
lots of stuff like we're probably gonna00:02:09
do we're gonna talk about hair um00:02:11
curly hair which is very very difficult00:02:14
to do um especially when you're trying to do00:02:16
real time stuff so it's gonna be super00:02:18
fun i'm really really excited00:02:20
about where this is going and i hope you00:02:21
guys are too uh all right00:02:23
so what are we gonna do today uh i want00:02:26
to00:02:27
um keep working on this feather asset00:02:30
because i want to give it more00:02:32
information uh i want to be able to00:02:34
split out my left my right and my spine00:02:36
i want a an attribute that goes from the00:02:38
very bottom to the very top00:02:41
um and then i want an attribute that00:02:42
goes along the length of these spines00:02:45
so i can i can use all that in in my00:02:48
uh my texturing software so let's get to00:02:50
work and let's get this done00:02:52
all right let's let's start working on00:02:53
this00:02:55
um all right so i'm going to00:02:59
let's pop into our feathers and so this00:03:01
is what i have so far00:03:02
so if i look here oh the first thing i00:03:04
want to do is i was working on this a00:03:05
little bit longer i didn't like00:03:07
how i have this feather if i plug this00:03:10
guy into here00:03:17
all right so if i have this feather00:03:19
coming into here um00:03:20
i just kind of uh shrunk it down um00:03:23
which i don't really like because that00:03:24
makes the density00:03:26
of these spines really really off00:03:29
from from the rest of the feather it00:03:30
makes these look like really really fine00:03:32
and small and the other ones are quite00:03:34
big so what i'm going to do00:03:36
is uh let's do00:03:39
objects and set this to dark00:03:44
so it'll burn out my eyes and your eyes00:03:47
so what i'm going to do00:03:48
is i can still get this this look uh i00:03:50
just it just i just have to do it00:03:51
through00:03:53
um the actual um00:03:56
the actual uh00:03:59
acid instead of this transform so uh so00:04:02
first thing i'm going to do is i'm going00:04:03
for this guy i'm going to bring my top00:04:05
length all the way down00:04:08
to about there and then i'm going to00:04:11
have to take down00:04:12
my left and right scale so my left scale00:04:16
that should come down oh that's that's00:04:17
working quite nicely it's working very00:04:19
nicely there00:04:26
that and then my right scale should also00:04:29
come down a bit00:04:31
actually quite a lot oh that's beautiful00:04:34
that is wonderful so we can see the00:04:36
difference if we go from this one00:04:38
to this one or actually uh00:04:46
oh yeah this is still drawing from this00:04:47
so that one got really small so uh00:04:50
yeah so we get rid of that and we can00:04:52
get rid of that and so that's our new00:04:54
kind of feather so i'm going to do the00:04:56
same thing to this guy over here so00:04:57
these guys these are my primaries00:04:59
these are my secondaries and these are00:05:02
my tertiary so let's just color these up00:05:04
so i can make sure they all go together so uh00:05:07
we'll do primary will be00:05:10
turquoise secondary will be00:05:14
yellow and coverts will be00:05:18
i don't know00:05:28
so i'm gonna do the same thing as i did00:05:30
here00:05:32
like this and let's plug this guy00:05:36
here00:05:44
view this and template that so i can see00:05:46
and do the same thing00:05:47
here so take our overall it's fine bring00:05:51
that way way way00:05:52
down and our left00:05:55
i'm gonna bring down as well00:05:59
i think i was just being like like lazy00:06:02
at the end of that last stream i was00:06:04
just like i just want to get this done00:06:05
and so uh you know sometimes sometimes you00:06:08
sometimes it happens00:06:09
right let's cut down00:06:19
cool and then this this guy this guy's00:06:22
quill doesn't go too far uh so let's do spine00:06:26
let's do bottom length let's do like00:06:29
0.01 length00:06:33
uh top segment length bend00:06:36
bottom length let's do 0.0100:06:42
yeah so really really short uh and i00:06:44
think i only need one segment there00:06:47
for that yeah so now uh00:06:52
my my feathers are just more consi more00:06:55
consistent across the board so if i were00:06:58
to00:06:59
let's save this first because i remember00:07:02
last time this was quite a00:07:07
task for my computer to handle and so00:07:10
let's00:07:11
go to other objects and let that cook00:07:12
four minutes00:07:17
hello rolex game uh i don't know what00:07:19
that language is00:07:21
yeah that's looking a lot better and it00:07:23
it calculated a lot a lot faster so00:07:25
these don't look00:07:26
so dense anymore so i got nice a uh00:07:30
a nice um what's the word i'm looking00:07:32
for00:07:34
uh distribution right like before these00:07:36
looked00:07:37
really really dense just because i was00:07:39
just shrinking everything down so it's00:07:40
basically00:07:41
all these spines were getting squeezed00:07:43
down into there so now they all kind of00:07:44
look00:07:46
it looks more more uniform so good00:07:48
that's that's that's what i want00:07:50
so that mission accomplished that that00:07:51
one's good okay uh next thing i need to00:07:53
work on00:07:54
is um i really don't like uh00:07:58
my um this proxy00:08:01
here so i have this guy i have this guy00:08:04
and i have this guy and i think i want a00:08:05
little bit more control00:08:07
over over my proxy geometry00:08:11
oh am i getting uh echo okay let's uh00:08:14
let me let me see let me see let me turn00:08:15
off00:08:16
my i tried i'm trying a new noise00:08:18
suppression filter but that might be00:08:20
giving you giving you echo let's turn let's get rid00:08:23
of00:08:24
yes okay let me know if that's helping00:08:27
the echo or not00:08:29
yeah so you might be able to hear my uh00:08:31
my air conditioning unit in the00:08:32
background but that's okay00:08:33
all right00:08:37
cool so let's get rid of that and uh00:08:41
okay yeah yeah all right00:08:44
so i'm gonna pop in here and uh so i'm00:08:47
gonna do00:08:48
so basically what i want is so if i draw00:08:51
this out00:08:52
so i have my spine i have my00:08:55
oh this is terrible drawing00:08:58
i have my left side00:09:03
i have my right side so what i want is00:09:06
one thing i want is i want00:09:08
an attribute that goes from zero to one00:09:13
over this entire thing um00:09:16
i probably want an attribute that goes00:09:18
from zero to one00:09:20
here from that way same thing00:09:24
zero to one going this way00:09:27
and then uh i want a mask that says this00:09:30
will be00:09:31
this will be red this will be green00:09:34
and this will be blue so i can mask this00:09:36
out and i'm going to use i'm going to00:09:38
texture this i believe i'm going to try to do it in00:09:41
substance designer i haven't touched00:09:42
substance designer for about a00:09:43
year so uh and they i just updated all00:09:46
to all the new adobe00:09:48
you know one but i'm mostly for most of00:09:50
this00:09:51
i think the the base level substance00:09:53
designer um00:09:55
should be fine um i'm not doing anything00:09:57
super crazy00:09:58
uh but we'll see we'll see so that's00:10:00
that's that's the plan so00:10:02
the first thing i need to do is figure00:10:03
out all right so my let's see00:10:06
here uh00:10:10
okay this is my yeah so this is my spine00:10:15
here um00:10:18
i think i grouped these already yeah00:10:20
spine00:10:22
i have left feather and i have00:10:26
right feather so i think i'm going to00:10:39
yeah so what i'll do is i'll build these00:10:42
just after build these attributes just00:10:45
after these00:10:46
groups yeah00:10:50
okay cool so what i want to do is uh so00:10:54
for my spine like i said i want a00:10:58
an attribute that goes from zero to00:11:01
one here00:11:06
yeah and i might already have that let's00:11:08
let's take a look00:11:12
accidentally hit my skylight button00:11:20
let's get rid of that get back in my00:11:21
feathers00:11:23
um popped in here uh yeah so what was i00:11:26
gonna do oh yeah uh00:11:28
let's see god oh man a little jittery00:11:31
today i think i had too much caffeine00:11:33
today00:11:34
my hands are a little off00:11:38
okay let's try this one more time uh00:11:42
split top bottom00:11:45
and i could also try to just go to00:11:52
there's a build i think the technical00:11:54
desktop will give me that00:12:37
pop into here grab this guy okay cool so00:12:40
uh looks like i have a curve u00:12:41
um i kind of don't trust it though00:12:45
let's see what it looks like so let's00:12:46
see what this curvy looks like so what00:12:48
i'm gonna do is i'm going to make a00:12:52
let's do a color i did this a little bit00:12:55
last time00:12:56
um but now i'm actually going to really00:12:59
control it00:13:04
so i'm going to do curve view i'm going00:13:05
to do point and i'm going to do00:13:08
uh ram from attributes and that's going00:13:11
to be curve u00:13:12
and just so i can see this like i did00:13:13
before i'm going to make this two really00:13:15
really garish colors like i'm going to00:13:16
make this one00:13:18
like this red and this00:13:21
green okay yeah so that's that's working00:13:24
i like that okay00:13:25
so i can take that curve u value and so00:13:28
actually what i want to do00:13:29
is i'm going to reset that actually so00:13:33
this is zero and this is one now it's00:13:34
it's a uh it's color00:13:36
right so this is uh this will be spine00:13:39
curve u00:13:48
just so i remember what that is okay so00:13:50
that's spine curve u00:13:52
and then i'm also going to make a00:13:55
uh pull this00:13:59
over here maybe get a little cluttered00:14:02
that's okay00:14:03
so i'm also going to make a um00:14:09
another one of these and this is just00:14:10
going to be my mask00:14:12
okay so this is going to be spine mask00:14:21
okay so that mask i'm just gonna do00:14:23
instead of uh00:14:24
instead of ramp from attribute i'm just00:14:26
gonna do constant and that's gonna be00:14:27
bright red00:14:30
so as i do this00:14:33
if i go and if i plug let's just plug00:14:37
yeah so let's plug let's look at the00:14:38
sweep00:14:43
so our sweep is what's wrapping the00:14:44
geometry so i'm hoping that the sweep00:14:47
will pick up these uh these attributes00:14:50
so let me00:14:51
let me look and see uh let's see uvs and00:14:55
attributes00:14:57
uh attributes from backbone curve00:15:01
um from cross structures this is perfect00:15:02
here so basically i can tell it so it's00:15:05
picking up everything except for p00:15:08
in up p scale scale orient00:15:12
rot pivot trans and transform okay so00:15:15
that that should pick up our color so00:15:16
let's00:15:17
just plug this in00:15:20
here yep so that's right so that's00:15:23
black down at the bottom down here and00:15:26
white00:15:27
all up at the top so it'll pick those up00:15:29
and then00:15:30
it is yeah so this is all red so that'll00:15:33
pick all that stuff up so that's perfect00:15:34
that's great okay so now i need to take00:15:38
these guys and kind of re-inject them00:15:41
back into uh00:15:45
into this stream so i think i can use an00:15:48
attribute copy to do that00:15:50
this is like almost like a um a00:15:53
compositing trick00:15:55
attribute copy so it's gonna be00:15:58
so it's this guy uh require geometry to00:16:01
copy two00:16:02
and require geometry copy from perfect00:16:05
so i'm gonna say grab this00:16:07
and grab this guy here00:16:11
and here i'm going to say uh source00:16:13
group don't need that nothing that00:16:15
attribute name so i'm going to copy cd00:16:18
and i'm going to give it a new name00:16:20
called uh spine00:16:24
curve u00:16:28
so now i have the spine curve u00:16:31
attribute and it's a red green and blue00:16:32
value00:16:33
perfect so i'm going to do the same00:16:35
thing i'm going to inject this guy back00:16:36
in so i'm going to copy that00:16:47
and this guy so this is the the red00:16:50
so i'm just going to call this uh00:16:52
instead of spine curve u00:16:53
i'm going to call this uh feather00:16:56
mask because that's going to get00:17:00
combined with everything else i have a00:17:02
feather mask spine curve u uh that is00:17:06
going to00:17:09
yeah so this is going to go into00:17:14
yeah so that's going to go into my merge00:17:22
and then it's also going to go00:17:27
into00:17:30
my sweep so if i look at my00:17:34
sweep here so if i want to check to make00:17:37
sure that went through00:17:39
i'm just going to use a quick attribute00:17:44
expression00:17:52
and i'm going to say cd00:17:56
and i'll just say real quick i'm going00:17:58
to say at00:18:00
feather mask00:18:07
so that should be00:18:11
maybe have to do v feather mask00:18:22
spell it correctly cool all right so00:18:24
there's feather mask so00:18:26
that's in there because i'm pulling that00:18:27
back out and then i can do00:18:29
v at uh let's say00:18:33
spine curve u spine00:18:46
curve u00:18:50
perfect so those those attributes are in00:18:52
there so i can pull those back out so ah00:18:54
good good good good so i'm gonna do i'm00:18:56
gonna keep this guy around00:18:57
uh i'll just disable it for now just so00:18:59
i know it's for checking00:19:01
uh so i'm basically gonna do the same00:19:03
thing for my left00:19:05
and my my right so that'll that that00:19:08
should be00:19:09
pretty easy so i'm going to make myself00:19:10
some room here00:19:13
all this stuff down00:19:22
my group for my00:19:27
okay so this is left feather so if i00:19:30
look at this guy00:19:31
i'm basically going to do00:19:35
the same thing so uh let's see do i have00:19:39
a there's an l quill there's an r quill00:19:43
left feather right feather let's see00:19:45
here we go all right so we have curve u00:19:47
i have a curve u00:19:48
and i have left u and a quill you00:19:53
and so there's just all sorts of crazy00:19:55
stuff in here so00:19:56
i think what i want to do i want to00:19:59
clean this up a little bit00:20:02
curve you spine you00:20:09
group group group so i wonder if i clean00:20:13
that oh yeah i clean i think i clean all00:20:14
that stuff out down here okay that's00:20:15
fine so i clean everything out00:20:17
uh down here so i don't really have to00:20:18
worry about that extraneous stuff00:20:20
uh i may have to under this attribute00:20:24
delete00:20:28
group delete00:20:31
okay cool yeah yeah so it's leaving the00:20:33
leaving those behind all right00:20:34
so let's do that same thing here so00:20:36
let's do a color00:20:47
and let's just see what this uh00:20:51
what this left you is00:20:58
right from attributes00:21:03
quill u yeah00:21:08
so it's black here and then it goes from00:21:12
zero to one perfect so that's left curve00:21:15
left quill u00:21:18
copy that00:21:24
okay this is my left will u and then i00:21:27
also want uh i also think i i want00:21:35
this spine u so i want this to go from00:21:38
zero to one and i think i think i don't00:21:41
have to i don't think i have to edit00:21:42
that from something else00:21:43
so i think i can build this from uh00:21:47
from some pretty pro just do a little00:21:48
attribute for this00:21:50
so we'll take this and we'll put this00:21:51
over here and so00:21:53
uh i think that's just gonna be for this00:21:54
this it'll just be um00:21:56
just a bounding box right this is the00:21:58
bottom of my bounding box this is the00:21:59
top of my bounding box00:22:01
so uh let's see00:22:06
let's do another color00:22:12
bounty box00:22:25
yeah so that's my bounding box but i00:22:27
really only want00:22:29
i really only want my y attribute right00:22:32
because this is going from zero00:22:34
to one in y so i can do00:22:38
let's do let's do an attribute00:22:41
expression00:22:45
i'm just going to modify my cd to just00:22:47
to be all my my y values00:22:48
so i'm going to say uh color and i'm00:22:52
going to say set i'm gonna say self00:22:56
dot y for all my00:23:01
self.y i wonder if i can just do self.y00:23:05
across the board00:23:09
yeah cool so bang00:23:15
there we go black at the bottom white at00:23:17
the very top00:23:18
fantastic so this is uh this quill you00:23:22
um and we'll call this quill00:23:26
oh man i'm running out of running out of00:23:28
names for stuff uh this is this is where00:23:30
i quill you00:23:31
because this one is what i call that00:23:34
spine curve u so i'm going to call this00:23:36
l00:23:39
quill curve u and then00:23:44
i'll call this just l00:23:48
grad yeah00:23:52
so i'm gonna do the same thing uh so00:23:55
let's00:23:56
scoot00:24:00
all this stuff over00:24:14
make some room pull this down00:24:30
okay and then i'm just gonna do the same00:24:31
thing so that's gonna be that attribute00:24:33
copy00:24:43
so i'm gonna copy from here into00:24:47
here so i want to copy my cd00:24:52
and this is quill u so let's keep this00:25:00
and new name00:25:10
actually now that i think about it i can00:25:13
give these all the exact same name00:25:15
to be completely honest so i can say00:25:18
we'll just call this00:25:19
this one00:25:26
length00:25:41
and paste relative reference right so00:25:44
those those two are exactly the same so here i00:25:47
should have00:25:48
a length u r g and b so those are all00:25:51
the same00:25:52
that's correct and then uh00:26:01
um this one this next one i'll call box00:26:04
you so i'm gonna do another actual copy00:26:13
so i'm going to copy my cd in in a new00:26:16
name i'm going to call this00:26:17
vbox u i'll just call b box00:26:22
b box y that'll work00:26:27
so now i have this b box y that goes00:26:29
from zero to00:26:31
two one00:26:39
so i have this link to you and then00:26:42
beatbox00:26:43
you here so i'm just going to take00:26:47
this entire00:26:51
thing and actually so i have a kind of00:26:53
junction point let's go00:26:54
null here00:26:58
this feeds into this and then this feeds00:27:00
out to these guys00:27:02
and i'm doing this just like kind of00:27:03
like chop this off and uh00:27:05
and reuse it00:27:10
l quill u this is our quill u00:27:13
okay so i'm going to copy ctrl c00:27:17
and ctrl v beautiful things about00:27:21
node-based stuff is you can do this00:27:23
so uh if i go over here now this guy is00:27:26
an elk u this is r will you00:27:30
all right and then the bounding box00:27:33
should be00:27:35
more or less the same zero to one00:27:38
and then this is going to get the same b00:27:42
box00:27:43
and actually copy00:27:48
cool so i'm just keeping my left and00:27:50
right in parallel00:27:51
as well so let's take that plug that in00:27:54
there00:27:55
let's take that and move this down to00:27:57
here00:28:01
and so let's check again so we have this00:28:04
length view00:28:05
we have uh and then we have00:28:08
our should have00:28:12
and then yeah b box y so uh length00:28:15
u and b box y00:28:18
so we can check this as well00:28:21
over here00:28:43
and so we're going to say00:28:46
let's see what do we say b box y00:28:57
nice nice there we go and then what did00:29:00
we say uh00:29:06
length u00:29:15
nice perfect yeah so we have this center00:29:18
the center line00:29:20
here now i could have done a bee box on00:29:22
this as well but00:29:23
there's a very subtle difference if i00:29:25
were to do a b box it would make a00:29:27
straight line from here to here00:29:29
what this does is it follows this curve00:29:32
so if i wanted to color00:29:34
like have the color sweep along with00:29:36
these curves00:29:37
that's what um that's what allowed me so00:29:39
like basically per strand00:29:41
uh coloration is what i'm setting up so00:29:43
that's working really really well00:29:44
okay00:29:51
okay and then this one will also need an00:29:53
extra color00:29:55
so that's gonna be my mask so i've00:29:56
already used red so i'm gonna do another00:30:06
color00:30:11
okay so this one is just going to be00:30:20
blue00:30:22
and that one i called what i call that00:30:25
feather mask00:30:29
so i'll just copy just pull this off00:30:33
and say this one this one goes here00:30:36
this one goes here that one goes there00:30:44
and then we'll do the same thing just00:30:45
grab these two00:30:49
ctrl c ctrl v00:30:54
just goes here and this goes over here00:30:58
and then this one will be bright green00:31:17
okay so00:31:20
let's look at v at feather mask00:31:30
awesome so now i have my red and my my00:31:32
blue and let's go ahead and plug that in00:31:34
as well00:31:35
so there's my feather mask aha great00:31:37
awesome so i have feather mask here00:31:39
uh let's make sure it makes it all the00:31:41
way down00:31:44
yep00:31:46
and yup okay00:31:49
so that's feather mask let's look at the00:31:51
other ones uh be boxy00:32:06
so that's top to bottom now my b box y00:32:08
looks like it's gonna it's white here00:32:10
because i don't have00:32:11
anything on my spine00:32:15
so my b box y for my spine is just the00:32:18
same as00:32:19
my length u00:32:22
so what i can do is i'll just copy00:32:25
i'll just make a copy of my my length u00:32:28
and uh i'll use that so let's see00:32:32
um don't use a copy i can use the00:32:35
attribute expression for that00:32:39
so uh yeah00:32:44
i'm trying throat's getting a little dry00:32:51
okay um00:32:54
yeah yeah uh00:32:58
tab attribute expression00:33:02
grab this plug it in here do00:33:07
custom and what i call that00:33:12
d box y00:33:20
and that's going to equal00:33:29
is that length view yeah lengthy00:33:34
be at length00:33:39
so this is going to go let's come in00:33:43
here00:33:44
go into there bang bang and so00:33:48
that should all filter down into this00:33:50
and yeah so there's my b box y so this00:33:52
guy00:33:53
is my b box y top to bottom that guy's b00:33:55
box y top to bottom00:33:57
um i should be able to get a length u00:33:59
here as well00:34:07
let's see where is it00:34:16
great so there's my length you black at00:34:17
the bottom white at the top00:34:20
black at the center white at the edge00:34:23
and then the uh feather mask00:34:31
boom so now when i when i bake this out00:34:34
when i bake00:34:35
this high-res and actually i might even00:34:37
have it on00:34:38
now that i've done it way up here i00:34:40
should also have it00:34:42
as the uh the curve so let's00:34:45
move this over here i should also see00:34:47
that in the curves as well00:34:50
yeah so it's going to the curves as well00:34:52
so i'll have it on the curves00:34:53
i'll have it on the high res geometry00:34:55
and then i will bake eventually bake00:34:57
that into00:34:58
the uh the proxy geometry so that that's00:35:01
working really well00:35:02
now let's let's work on our proxy00:35:03
geometry a little bit so00:35:05
uh i'm coming out of00:35:12
let's see00:35:17
i have something templated00:35:29
ah okay yeah so this is my um00:35:32
this is the00:35:44
this is my my template geometry uh or my00:35:47
um00:35:48
my uh uh god what's the word i'm looking00:35:50
for uh00:35:58
geometry proxy geometry um so i don't00:36:01
really like the way this is this is this00:36:03
is working like this uh so i think maybe00:36:07
um this i might be running up the wrong00:36:09
i'm gonna be barking up the wrong tree00:36:10
here00:36:11
but i just don't like i don't like the00:36:13
bound like i can't control it like it's00:36:15
it doesn't really have any uvs00:36:17
um yeah it's just uh just kind of there00:36:21
and i won't be able to like if i need to00:36:23
deform this00:36:24
along this way eventually in a rig or00:36:26
something like generally when you have00:36:28
feathers like when they kind of00:36:29
they scoop up like this like they have00:36:31
like this kind of uh00:36:33
uh like if you look at eagles in flight00:36:35
like their feathers kind of go00:36:37
like that at the edge so we'll do00:36:39
something like00:36:42
like that so i need divisions along00:36:45
along that that proxy feather00:36:47
to deform that um00:36:50
and it's a really long piece of geometry00:36:52
so00:36:56
i could subdivide it but i don't really00:36:58
need any subdivide divisions along00:37:01
like this way i just need them that way00:37:06
so00:37:09
hmm00:37:15
i'll keep this around but i think i'm00:37:19
going to come00:37:20
off of my actual00:37:27
yeah i'm gonna come off of my spine00:37:28
geometry00:37:34
here00:37:49
now because my spine geometry is bent00:37:51
okay maybe00:37:52
maybe i can do a this might be00:37:56
really really silly uh00:38:07
let's do00:38:11
i'm going to do this really strangely00:38:12
i'm going to make a00:38:16
i'll make a grid00:38:23
and i don't really need i only need two00:38:25
and two00:38:26
and i can leave this thing as bonkers00:38:28
huge00:38:29
as i as i want it right so i'm going to00:38:32
do now i'm going to do a copy00:38:36
and transform00:38:46
we may delve into uh a bit of um00:38:52
of uh expressions here so i have00:38:56
so this is gonna keep moving up and up00:38:57
and up and up every time00:39:00
right so uh what i want00:39:03
is i want00:39:06
to be able to put the top00:39:10
of these guys well let me just make sure00:39:12
this works first let me let me see if00:39:13
this works first00:39:14
so what i'm going to do is i'm going to00:39:16
just boolean uh with a shatter00:39:20
this proxy geometry so let's try that so00:39:22
let's do00:39:26
boolean shatter i'm gonna do this guy00:39:30
with that guy yeah00:39:33
cool that worked that worked really well00:39:34
um but i need to make sure that00:39:36
this will uh update with my00:39:40
uh update with my um with my feather00:39:43
because right now if i change my feather00:39:44
this isn't going to this isn't going to00:39:46
update but let's also make sure that i00:39:48
have00:39:51
let's turn on my00:39:54
numbers00:39:58
so it looks like i have double numbers00:39:59
in here so i'm going to go ahead and00:40:00
fuse this as well00:40:02
views00:40:09
cool if it's dumb and it works00:40:12
it ain't dumb that's that's my that's00:40:14
that's my story i'm sticking to it now00:40:15
if i had like some gigantic feather00:40:18
um i might have to deal with with this00:40:20
but00:40:21
i think this is working as it is it's00:40:23
allowing me to just00:40:24
just divide my my feathers00:40:27
uh along one one dimension because00:40:30
feathers just go like this00:40:32
they don't really i don't really want to00:40:34
see them fold00:40:35
right i only need to to deal with that00:40:37
so all right so that's worked00:40:38
um so let's see um my00:40:43
let's see what is this going to put out00:40:46
so i want to get00:40:47
the uh the top00:40:51
of this guy right so i have if i have00:40:54
let's say let's do 10 because that's00:40:56
eating so i have 10 divisions00:40:59
um so it would be 1000:41:03
so it'd be the length so i'm basically00:41:05
dividing this up by 10 so it'll be00:41:06
however tall this is00:41:08
divided by my total number00:41:11
so let's see if we can get00:41:15
that uh00:41:22
so i think this expression would be00:41:28
so this would be b box00:41:33
okay so b box string00:41:39
uh surface node and then type so that00:41:42
would be00:41:43
d underscore y00:41:47
max cool so i can do00:41:50
um quotation mark dot dot slash00:41:55
bound round one00:42:06
okay and then00:42:09
capital d underscore y max00:42:18
awesome cool right so that looked about00:42:21
right but i'm making i'm moving00:42:23
so we can almost see like there's this00:42:24
is that exact height right00:42:26
so this guy's that exact height so i00:42:27
need to divide by this total number so00:42:29
i'm going to say00:42:31
copy parameter and just to finish this00:42:34
out divided by and then paste relative00:42:42
reference00:42:52
so there we go cool00:43:09
that looks about right so i'm gonna do00:43:11
this until these look about square00:43:15
i think six is okay00:43:18
let's turn off some of this clutter00:43:23
yeah that feels that feels okay not not00:43:25
the greatest but it gets the job done00:43:27
gets the job done great so and then the00:43:30
last thing i think i'll do00:43:31
is i will i might have to do this as00:43:33
well00:43:35
uh i need to give the this guy00:43:38
um00:43:41
uvs as well so i want to be able to uv00:43:44
this00:43:45
or i want it to come out with uvs built00:43:47
into it so00:43:50
once again this is going to change right00:43:52
if i change00:43:53
if i change the length of my feather if00:43:55
i change the00:43:56
the the length of the the spurs that00:43:58
come out the side that's all00:43:59
always going to change so this is very00:44:03
dynamic right so i want to be able to uh00:44:08
keep that dynamism00:44:09
built in00:44:16
yeah so i'm going to do a00:44:19
i'm going to just do a uv project00:44:23
or uv uv quick shade00:44:33
and i want to project through these00:44:35
z-axis00:44:42
that's okay but it's a little long00:45:00
so i want the y to be one so i'm gonna00:45:01
have to take00:45:03
and decrease my00:45:06
z okay okay so that's about00:45:10
point one so if i look at00:45:14
my uv viewport00:45:19
yeah that feels about right so that00:45:20
would be that would be my00:45:22
my overall overall feather so00:45:28
this would be since it's a fraction it's00:45:31
going to be00:45:33
1 over something00:45:39
i think it'll be 1 over my00:45:43
height that same expression let's try it00:46:05
one over00:46:12
x00:46:20
maybe it's just oh it's just the my my00:46:23
xmax right00:46:24
so this goes to one and this should be00:46:26
about point yeah so 0.113 so that00:46:29
should work we'll see we'll see what00:46:32
this does okay00:46:42
great so now i have uh00:46:45
this uv in here so let's see if00:46:49
this works out uh so let's plug00:46:53
this guy in here and let's go up and00:46:55
we'll have a look00:46:57
that's my proxy uh actually i'm gonna00:46:59
take i'm gonna duplicate this00:47:01
because i don't wanna mess up what i00:47:02
already have here this is my testing00:47:05
feather00:47:07
so if i take my spine length00:47:16
no i want those i want those to stay00:47:17
square00:47:20
so it's not quite right it's not quite00:47:22
right00:47:44
so let's see let's let's think about the00:47:46
math of this00:47:47
uh so i have00:47:54
i have uh my width00:47:57
divided by my height has to equal00:48:02
one00:48:05
right because i want these to be in a00:48:06
one to one uh uh00:48:08
one to one ratio oh no no no no no00:48:12
uh00:48:15
my what my height equals once maybe it's00:48:18
my00:48:19
maybe it would be my00:48:24
width over00:48:31
b y max00:48:40
oh i think that's doing it i think00:48:42
that's doing it now00:48:45
let's go back up to the top and test00:48:46
this00:48:57
yeah those are staying square now00:49:05
so this is what blows me away about00:49:07
houdini like you i don't know00:49:08
if i could do this in maya like to just00:49:12
like dynamically00:49:13
change my uh my uh00:49:17
my uvs uh based on my geometry like00:49:20
that's it's crazy but you can do this like look00:49:22
at this it's just00:49:24
you know it's it's keeping that same00:49:26
ratio00:49:27
the entire time no matter how big or00:49:29
small it is that's that's00:49:31
that's amazing right a little bit of00:49:32
math goes a long way00:49:34
all right so i think that's working so00:49:37
remember this is my test this is my test00:49:38
feather so00:49:39
um i can so i can't break anything else00:49:42
so that's what i'm gonna do uh so let me00:49:45
make sure that i still have00:49:46
everything coming out of here that i00:49:48
need um00:49:51
so i'm gonna look at this so there's my00:49:53
b box y it's my feather mask00:49:55
uh feather mask and i should get a00:49:58
length yeah length u00:50:02
perfect sweet um and then i should have00:50:06
groups that are left feather right feather and00:50:10
spine if i wanted to do anything with00:50:11
that so00:50:12
i need to need to um remove00:50:16
any of these kind of extra so i want to00:50:18
keep v box00:50:20
uh why i want to keep feather mask i00:50:22
don't need that left u00:50:24
i don't need the quill i don't need all00:50:25
that stuff so we're going to go back in00:50:27
here and we're going to go into i think i00:50:30
should00:50:31
actually00:50:34
well that's fine that's why i can do it00:50:49
i don't need that anymore it's just kind00:50:50
of floating in there00:50:52
these are my outs00:50:57
contacts here00:51:05
all right00:51:08
let's see let's see let's see00:51:11
all right what did i say i wanted to do00:51:13
um00:51:17
here we go00:51:20
uh group delete00:51:31
uh left feather right feather spine00:51:33
that's fine and then00:51:34
attribute delete i want to delete00:51:38
everything except00:51:41
for be box y00:51:44
feather mask and00:51:51
length you so i'm going to do a star00:51:54
so i'll get rid of everything00:52:00
nope that was on my00:52:05
there we go so my point attributes i'm00:52:08
going to say get rid of everything00:52:11
except for b box y00:52:14
oh nice little drop down there i like00:52:16
that that's new00:52:18
or at least new to me v box y00:52:21
i want to keep my00:52:25
length u00:52:32
and my feather mask00:52:36
it's always a good idea to just kind of00:52:37
clean this stuff out especially if00:52:39
you're working in a team00:52:40
um you should only pass on stuff that's00:52:43
uh that's actually00:52:44
relevant so i got my proper groups and00:52:47
my length u00:52:48
and all that stuff so i'm just going to00:52:49
copy this see00:52:51
and come over here00:52:58
delete00:53:01
and that's fine yeah yep cool00:53:07
so if i come out to my feathers so i00:53:10
have my b box00:53:11
uh why another mask00:53:14
length u and then my three groups on00:53:17
each one00:53:24
oh uh the one thing i do want to since i00:53:26
have those i know those uh those uvs are00:53:28
working i'm also going to delete00:53:32
as well on here uh oh00:53:35
and these are also all my points i want00:53:36
those on my my vertices00:53:39
so uh we'll take and00:53:42
let's get rid of that shot material path00:53:44
so we'll do an attribute promote00:53:52
and we'll promote point to vertex and00:53:55
that will be texture uv00:53:57
so that goes my vertices because that's00:53:59
where uvs should live00:54:00
and then i'll do an attribute delete and00:54:02
delete this sharp material path my00:54:10
primitives00:54:14
so it should get rid of yeah it gets rid00:54:16
of that that checkerboard that's on00:54:17
there00:54:20
so i know my my uvs are working i don't00:54:22
need to see that that checkerboard00:54:23
um because i'm going to i'm actually00:54:25
going to edit these00:54:26
i'm going to scoot each one over a00:54:28
little bit so00:54:29
uh there is one more thing that i want00:54:31
to do uh left right00:54:34
if i go to here i have my left might00:54:36
have my spine my left00:54:37
my right and then i think what i'm going00:54:39
to do as well is i'm going to put00:54:40
a proxy00:54:44
on here so i can control00:54:47
uh how many divisions i have on my proxy00:54:51
as well so00:54:53
um this guy00:54:56
or no this guy right so this is all00:54:58
controlled00:54:59
by that so uh let's keep that same kind00:55:03
of thing going on so left right uh spine00:55:07
left right i'm going to do edit parameter interface00:55:18
oh that was terrifying save brian save00:55:22
save yourself uh all right00:55:26
get a parameter for interface spine left00:55:28
right and i'm gonna make another00:55:30
folder here00:55:34
this will be proxy00:55:38
this will be grab an integer put that00:55:40
there00:55:46
proxy proxy00:56:00
divisions00:56:04
and um00:56:16
yeah proxy divisions so let's say accept00:56:18
i should now have a00:56:28
hmm00:56:30
i need to put it in the actual00:56:33
and let's set that to six00:56:37
and we'll say edit00:56:40
copy parameter come up into our copy00:56:44
and say paste relative reference00:56:50
cool and then up top in our bb feather00:56:54
what i'll do is i'll just grab i'll say00:56:58
type properties go into my parameters00:57:03
and just go and from nodes00:57:12
there's my controller00:57:21
another con just take my proxy and just00:57:25
pull it over here and say00:57:27
apply so now if i go up to the top00:57:32
i now have a proxy and that gives me six00:57:35
so i can do00:57:37
as many as i want00:57:40
cool all right so uh save this save00:57:43
let's say uh save node type00:57:49
match current definition i'll tell this00:57:51
one to also match current definition00:57:56
and so there we go so on all these if i00:57:58
look at each one of these00:58:00
i should get00:58:08
that's why okay so this is becoming it's00:58:11
one of the small thing00:58:12
uh so my my my base is00:58:18
not being calculated okay cool so i just00:58:20
need to move this down to my d00:58:22
x min d y min that's going to be my00:58:25
center00:58:26
yeah okay so i'm just going to open this00:58:29
back up uh allow editing of contents and these00:58:31
are this is just how you kind of00:58:33
iterate through a system it seems really00:58:35
boring00:58:36
but uh it will pay off trust me i keep00:58:38
on saying that it will pay off00:58:40
especially when we get to the texturing00:58:41
phase it'll be really really cool that's00:58:42
stuff that you can do with this00:58:44
um so in my copy let's take00:58:55
let's take our pivot transform00:59:08
let's look at this from the front view00:59:18
cool okay so that first copy so if i00:59:20
take my00:59:21
uh y my00:59:24
pivot translate y and i start to scoot00:59:27
that down00:59:37
maybe if i bring this one down center01:00:07
okay let's take this guy and we'll do01:00:10
this and we'll do y01:00:12
min01:00:24
just one no01:00:43
minus one01:00:46
minus one01:00:55
yeah that looks a little bit more even01:00:57
it looks a little bit more even so let's01:00:58
go back up01:01:00
and let's say save node01:01:03
type properties01:01:06
yeah that feels much better all right01:01:08
that's that's that feels way better01:01:11
yeah yeah yeah cool01:01:13
[Music]01:01:17
definition all right01:01:22
bang01:01:24
like that all right awesome so now i01:01:27
don't need these anymore01:01:30
save okay01:01:33
so these are all going out to the01:01:36
actual wing so i'm going to switch these01:01:38
all back to01:01:40
that and those will just kind of sit off01:01:42
the side and those will go out to01:01:44
out to the wing um01:01:48
so now what i need to do is i need to01:01:52
i'm actually going to edit these guys as01:01:54
um01:01:56
uvs because i want them one right next01:01:58
to01:01:59
one right one right next to another uh01:02:04
so01:02:11
so if i take and i merge this01:02:14
and this and this01:02:27
so these are my three feathers and01:02:28
they're all merged01:02:31
merged together so if i look at01:02:36
so these are all stuck stuck together so01:02:38
i'm going to take my primary i'm going01:02:39
to leave alone01:02:40
actually no i'll put a i'll put a uv01:02:42
transform on on each one of these01:02:44
so uh let's do tab uv01:02:47
transform01:02:54
i'm just gonna go here press enter01:02:58
actually i'll just go ahead and set this01:03:00
up on each one of these01:03:34
cool uh so i just scooted those over so01:03:37
that01:03:38
and if i do a uv01:03:47
quick shade01:04:00
one two01:04:03
three this one's still a little squish01:04:05
but i think that's okay that's okay01:04:06
um the other thing that i could do with01:04:10
this is instead of these uv transforms i01:04:12
don't think about it01:04:17
that01:04:20
do this i could just do a like a uv01:04:24
layout01:04:25
and see what that gives me so uv layout01:04:37
and i don't want to say none01:04:40
i still want to be up and down uh and01:04:43
then scale islands to match01:04:44
surface area so there that is if i want01:04:47
my01:04:48
my textile density to be you know the01:04:51
same across the board i can do that01:04:58
so um01:05:14
yeah i think i'll do that i'm wasting a01:05:16
fair bit of space though01:05:22
hmm i want to use as much texture space01:05:25
as i01:05:26
as i can because i'm going to need a01:05:27
pretty large texture for this01:05:29
um to get that detail in there so01:05:32
i wonder if there's a way01:06:08
yeah what have i done01:06:12
oh it's packing okay let's just do that01:06:28
could be the scale as well largest pack01:06:31
there we go01:06:32
um01:06:36
let's do like 1601:06:39
between here and here so the stuff01:06:41
system butt up right next to each other01:06:43
and then spread islands yeah i think01:06:45
that's as good as i'm gonna get right01:06:47
um01:06:51
yeah i think that's good that's pretty01:06:53
good that's pretty good so01:06:55
um some of my some of my feathers are01:06:57
gonna have higher density than others01:06:58
but i think01:06:59
that is okay for what i'm doing here01:07:01
okay so01:07:02
uh let's get rid of that and let's get01:07:04
rid of these guys don't have to use01:07:06
those anymore01:07:12
experiment right so this is like for my01:07:15
this is for my text string basically uh01:07:17
okay01:07:18
so uh i want to be able to01:07:23
split these back out into each01:07:26
part so i think what i'm going to do is01:07:29
i'm going to group01:07:30
group these before i bring them in01:07:33
so let's do01:07:37
a group01:07:45
primary proxy01:07:57
it's going to be secondary proxy01:08:07
and this will be01:08:12
cove proxy01:08:19
i'll just call that pry proxy because i01:08:21
don't want to keep spelling primary01:08:23
bam like that okay so now here01:08:27
so after we packed all these guys01:08:28
together we have these three groups and01:08:30
we can split them01:08:31
back out to do whatever we need to do01:08:33
with them so let's do that01:08:34
so i'll do a blast01:08:44
this will be primary01:08:49
and delete non-selected01:08:55
scc01:08:58
and cov01:09:04
cool so i have my three different types01:09:06
of feathers so i brought them all01:09:07
together01:09:08
i laid out their geometry and then i01:09:11
split them back apart now01:09:12
mind you all this stuff is still going01:09:14
out to my01:09:15
my actual feather out here so that's01:09:18
really cool um all right and actually01:09:23
now i think about it i need01:09:29
this stuff to continually go to update01:09:33
because i need those new uvs01:09:36
because i'm going to export that whole01:09:37
wing as well so i can see it working01:09:40
in my texturing package so01:09:49
so we'll continue to kind of scoot that01:09:50
down until01:09:52
we get to the end right so now these are01:09:55
these are uvd01:09:56
so uh so this is my my low resolution01:10:00
geometry01:10:03
and so what i'm going to do01:10:09
is i'm actually going to what i want to01:10:10
do is i'm actually going to merge01:10:12
my low res and my ultra high res and i01:10:14
want to scoot these over so i'm01:10:15
basically going to do the01:10:16
almost the same thing that i did for my01:10:19
uh for my um01:10:25
oh what's the word i'm looking for uh01:10:27
for the for the uvs i'm going to do the01:10:28
same thing01:10:29
for the geometry and then i'm gonna bake01:10:31
all that data01:10:32
from my high resolution geometry into my01:10:35
low resolution geometry and that will01:10:37
allow me to take it into my texturing01:10:38
package01:10:39
be it substance designer substance01:10:40
painter i even i tested this um01:10:43
at a lab computer and i didn't have01:10:45
substance painter so i just i did it in01:10:46
blender01:10:47
um so it's all the same concepts just01:10:49
black and white remapping values01:10:51
um making your primary like a pvr shader01:10:54
so your roughness your metallic01:10:58
your normal and01:11:01
roughness metallic normal oh and base01:11:04
color or albedo01:11:09
so moving along moving along feeling01:11:12
good feeling good about today01:11:18
all right so01:11:21
i already have my proxy groups here so01:11:24
proxy proxy proxy01:11:25
i need to make a hi-res group as well01:11:28
so i'm just going to copy this and go01:11:31
here01:11:33
i'm going to call this pre-hi01:11:39
all right it's gonna get copied01:11:46
hi01:11:50
and this guy's gonna get copied01:11:59
hi okay uh so let's see01:12:04
um so there's01:12:08
my out main let's drop that off to the01:12:11
side01:12:12
this is going to be this is my high res01:12:14
here01:12:17
perfect okay so i'm going to take01:12:21
this guy and this guy and merge them01:12:32
so it's both of those together so that's01:12:34
my high res and my lower resolution do01:12:35
the same thing01:12:36
for the other ones so01:12:40
shuffle this off to the sides get a01:12:41
little messy okay01:12:45
so i want01:12:50
guy and01:12:53
this guy01:13:03
we can see how these lay on top of each01:13:06
other01:13:07
uh and then same thing this guy and01:13:10
this guy01:13:20
and i think maybe my padding is a little01:13:23
bit too big01:13:24
yeah a little bit i think i'm wasting a01:13:25
lot of space in here01:13:27
so let's go back and do this one more01:13:30
time01:13:40
keeping as tidy01:13:45
possibly can01:14:10
right cool all right so what i'm going01:14:11
to do is i'm once again come back in01:14:13
here uh allow01:14:14
editing of contents pop in here and01:14:18
maybe my01:14:19
bounds01:14:22
are a little bit too big so let's do01:14:25
actually i wonder what happens if i just01:14:26
do zero01:14:49
so that's a little bit too tight for my01:14:51
liking i do want01:14:53
some so i think actually what i'm going01:14:55
to do is i will01:14:57
uh i'll make a controller for this or a01:14:59
proxy01:15:00
uh so i'll just call this uh01:15:04
edit interface01:15:08
and we'll say a float value01:15:11
we'll call this padding01:15:28
copy this01:15:55
all right uh and then same thing i'm01:15:57
gonna save this because sometimes it'll01:15:59
crash01:16:00
type properties01:16:04
proxy node properties from nodes01:16:09
another con proxy and drag that padding01:16:18
over01:16:28
yeah that 0.01 maybe 0.0501:16:31
yeah that feels good that feels good01:16:33
just a little bit01:16:35
of padding on everything and uh yeah so01:16:37
let's say01:16:38
save no type01:16:43
match current definition01:16:56
should now get a little bit tighter01:16:59
response01:17:00
from yeah there we go01:17:04
sweet awesome so why am i doing all this01:17:07
because i want to be able to split these out01:17:11
into their parts so but i want to01:17:13
transform them first01:17:14
so i'm going to put a transform here01:17:18
on each one of these01:17:27
and then i'll merge all three of these01:17:29
together01:17:31
i'm gonna split this back out again so01:17:32
let's do01:17:36
okay so take my secondary01:17:41
scoot that over01:17:48
and same thing here it's gonna be 0.401:18:06
so now i have my high res's and my low01:18:08
res's01:18:09
up more or less lined up01:18:16
and ready to bake01:18:22
so now i can split these back out to the01:18:25
high res and01:18:26
the low res so let's do that let's do a01:18:30
i think we just do a split literally a01:18:32
split because i only want two01:18:37
so the split should be able to say01:18:41
uh group i think i can just do star01:18:44
high yeah so star high01:18:48
is going to give me my high res and01:18:50
actually you know what i'm going to do01:18:51
star proxy just to keep the01:18:55
order correct so there's my proxy and01:18:57
then on the other side here01:19:01
is going to be my high res01:19:05
and all that luscious information that01:19:07
we built before01:19:08
is all going to be transferred down here01:19:20
okay01:19:25
and then i believe if i give you five01:19:27
yeah so there's my01:19:29
there is my also my uh uh01:19:34
what i'm looking for um uv map01:19:37
it's my uv map okay so now here's the01:19:40
fun part01:19:41
one i'm going to save this save so what01:19:44
i want to do so this is my proxy and01:19:46
this is my hybrid so i'm going to use01:19:47
a labs tool if you're using houdini and01:19:51
you're not using01:19:52
the side effects labs you are doing01:19:54
yourself a huge disservice there is so01:19:56
much cool stuff in there01:19:59
and you don't even know it's amazing so01:20:01
i'm gonna do a uh01:20:04
labs i always forget which one it is01:20:06
there's two bakers01:20:08
um i think it's the it's the matchmaker01:20:10
yeah01:20:17
so what it does is it takes in a low01:20:18
resolution geometry and a higher01:20:20
resolution geometry and i can01:20:22
bake out all this crazy stuff which is01:20:25
fantastic so01:20:27
i'm just going to bake out so there's my01:20:28
low res right remember this is my low01:20:30
res01:20:31
and that's going to be my high res01:20:37
and so for my first bake i'm going to01:20:39
keep this quite low i'm going to keep it01:20:40
like01:20:41
5 12 by 5 12 because i want to make sure01:20:43
everything's worked uh01:20:45
so what do i want to transfer uh i want01:20:47
to transfer a normal map01:20:49
uh an opacity map01:20:54
i don't really need roughness i don't01:20:55
have any diffused color and i don't have01:20:57
any metallic01:20:58
but what i do want to pass in is let's01:21:01
see01:21:02
i don't really even think i need maybe01:21:04
alpha um01:21:06
uh and then so vertex color01:21:10
i think i need that ao might be able to01:21:12
use that um01:21:14
position i might be able to use that uh01:21:17
and then01:21:22
yeah and then maybe i'll export my low01:21:24
in my high as well into fbx's01:21:26
and now now here's the awesome part the01:21:27
custom attributes so i can write so this01:21:30
is why i made all these uh vectors01:21:32
because01:21:33
this bound bound y that's a color i mean01:21:35
even though it's black and white01:21:37
it's still you know data it's just all01:21:39
the same01:21:41
um yeah so that's writing from01:21:46
this guy right so what i can do01:21:49
is i can say add attribute01:21:53
and so i can say let's hopefully be01:21:56
box y01:21:59
and another attribute this is going to01:22:01
be feather mask01:22:04
i'll make sure i spell these correctly01:22:07
because i have had times01:22:09
where if i don't spell this correctly it01:22:11
will crash01:22:12
so be very careful01:22:21
okay so let's save this and it's going01:22:24
to spit out01:22:25
to my hip render hip name and then01:22:28
channel i don't want that let's do01:22:30
feather01:22:34
feather mesh01:22:38
maps01:22:43
and i do want to keep that channel there01:22:44
um i think01:22:46
i want these to be png i think01:22:49
should work save this again and let's01:22:52
let this rip see what happens01:23:00
hey heart dick how you doing man01:23:08
we are texturing uh today we are01:23:11
texturing our uh well we're starting to texture01:23:15
the uh the feathers so01:23:18
that is not looking promising but let's01:23:20
see let's see what we get01:23:21
um let me go and look that01:23:33
let's go up get01:23:36
let's look at that data and see what01:23:38
came up01:23:53
right so these are what came out so if01:23:56
we look here01:23:58
oh this is looking really good and this01:24:00
is this is only 512 right01:24:02
i haven't even bumped this up to a01:24:03
really high value but there's my opacity01:24:06
uh there's my well that's my alpha uh01:24:09
this is my01:24:10
ambient occlusion01:24:13
i'm sorry my my mouse wheel is going01:24:15
crazy01:24:18
all right so there's my opacity kind of01:24:21
zoom in a little bit01:24:22
so it's pretty crunchy because it's only01:24:23
512 but i'm getting01:24:25
like this really really nice you know01:24:29
so i'm getting some more a stuff in here01:24:30
because i don't have the uh the01:24:32
resolution to control that but01:24:35
it'll look good it'll look good uh all01:24:37
right so there's that01:24:44
uh so it's my amity occlusion01:24:48
there's my b box y look at that right01:24:50
it's a nice little01:24:52
black uh i don't have any color so that01:24:55
that came out black and then there's01:24:56
there's my mask that's what that's01:24:59
what's really gonna01:25:00
gonna help me so now i can separate my01:25:02
spine texturing01:25:04
from my uh from my left hand side to my01:25:07
right hand side so if i want01:25:08
one side of my feathers to be one color01:25:09
one side of my feathers to be in the01:25:11
other color or one type of material and the other01:25:13
type of material i can do that so01:25:15
very very powerful stuff and then this01:25:16
is my uh length view so if i wanted01:25:19
them to change color from the root to01:25:22
the tip i could do that as well01:25:28
my normal app is looking pretty good01:25:31
it's my position01:25:33
now my position i don't think i'm going01:25:34
to use very much because01:25:38
uh01:25:40
one i think i have to make this an exr01:25:42
and two i move them around in space so01:25:44
they're not01:25:45
zero centered anymore so that might not01:25:47
work01:25:48
but uh there is one thing i did want to01:25:50
look at01:26:02
so my b box y is still01:26:05
really straight now that i'm looking at01:26:09
this01:26:10
so i might have to go back and rework01:26:12
that i still want that b box y like i01:26:14
want each one of so there's a gradient so if01:26:17
we look01:26:18
at look really really closely01:26:21
there's a gradient between this and this01:26:23
i want that gradient i want this guy to01:26:25
just be01:26:26
solid right i want it to be a solid01:26:28
color because i want to be able to color01:26:30
like that entire quill one color i don't01:26:32
want it to01:26:33
to bleed over to another color so maybe01:26:36
doing that v box wasn't the greatest01:26:37
idea01:26:38
um so we can we can we can rework that01:26:42
eventually uh maybe i'll do it between01:26:43
the streams um01:26:45
so so now i know i don't really need01:26:49
so let's look at01:26:54
let's do feather mask see and we'll look01:26:57
at feather mask01:26:59
okay so there's a feather mask so this01:27:00
is what these will look like in01:27:02
in actually in context01:27:08
okay so let's bump this up to 102401:27:12
save again let this run01:27:35
so obviously the bigger the uh the01:27:37
bigger the image the longer it's going01:27:38
to take to bake01:27:43
okay so that's feeling a little bit01:27:45
better a little bit better01:27:51
48.01:27:59
is that uh01:28:04
uh my biggest feather is actually01:28:06
getting the least amount of01:28:08
of uh of texture space01:28:32
waiting on this to finish compositing01:28:59
yeah that ambient occlusion usually01:29:01
takes a little bit of time i probably01:29:02
won't even end up using that01:29:04
but uh we'll see we'll see01:29:20
yeah that's much better that's much01:29:22
better so i think i'm liking where this01:29:23
is01:29:24
where this is at so maybe uh yeah 2k01:29:28
but i'm uh so the only thing the thing01:29:30
about this is you're like oh my god 2k01:29:32
that's like a huge texture but the01:29:34
problem the thing is01:29:35
is this one texture is going to texture01:29:38
almost my entire wing01:29:40
so instead of having one like like a01:29:41
bunch of little individual01:29:43
textures i have one really large texture01:29:45
that i can that i load once and then01:29:47
it just works so this one's looking01:29:49
really nice this is looking really nice01:29:50
let's look at what that normal looks01:29:52
like01:29:59
so normal maps looking good um01:30:02
yeah some good overall like this is this01:30:05
is working01:30:06
really well so that's what's going to01:30:09
allow us to give this thing give this01:30:11
some depth overall um when we when the01:30:15
when the light rolls across it you're01:30:16
going to see that light like01:30:17
hit those hit those bumps really nicely01:30:19
and it's going to give it that ribbed01:30:21
that overall ribbed look um01:30:26
all right so the last thing i want to do01:30:28
uh inside of houdini well not the last01:30:30
thing i want to do01:30:31
for this section is i do want to address01:30:33
that01:30:34
um the uh the b box y01:30:38
that i that i that i set up way up in01:30:40
here uh because i don't i really really01:30:42
want to have the ver i'm being i'm01:30:43
probably being a little bit too spicy01:30:45
too picky but i want each one of these01:30:47
barbs01:30:48
to have a uniform kind of01:30:51
value instead of just slowly gradating01:30:54
like it's like these little things like01:30:55
when you and i don't know how close i'm gonna get01:30:57
to this but it's like these are the01:30:58
things i really consider and01:31:00
um sometimes you can you have the time01:31:02
to do this and sometimes01:31:03
you don't um but uh01:31:08
this is kind of an academic exercise i01:31:10
want to get as precise as i can01:31:14
excuse me but this is looking really01:31:16
nice and like01:31:17
so i've gone from you know millions of01:31:18
polygons to you know whatever01:31:21
this times that is uh and my my uvs01:31:25
update if i want to change this is all01:31:27
like 100 procedural so it's a beautiful01:31:29
beautiful system01:31:30
uh okay so01:31:36
do allow editing of contents again01:31:39
coming here01:31:40
and so that is let's see01:31:55
there's something templated on just01:31:57
templated down here01:31:59
okay so let's see escape escape escape01:32:03
escape01:32:06
okay so this is my top line and this is01:32:10
my bottom line my top line is coming out01:32:12
into here and grabbing01:32:15
this attribute remap over01:32:18
all so i have this curve u01:32:23
and i'm copying01:32:28
curb you to left you01:32:33
ah that's what i was using that for okay01:32:35
okay okay okay01:32:37
and this is quill you okay so left you01:32:43
so i come to kill you01:32:54
bounding box okay so let's just replace01:32:56
this guy01:32:57
with a different color node someone's a01:33:00
color01:33:02
and here instead of b box i'm going to01:33:04
say01:33:07
rant from attribute01:33:11
and that ramp is going to be left you01:33:15
yeah there we go that's what i wanted so01:33:18
if we look01:33:19
very very closely each one of these01:33:20
little quills01:33:23
is the same color so i can i can push01:33:25
that color01:33:27
onto each little one so let's that's01:33:28
that's much easier so that was left you01:33:30
so i'm just going to replace01:33:33
that b box with left you01:33:36
so cd b box y01:33:42
and i might need these later so i'm just01:33:44
going to keep those around01:33:58
this guy instead of bounty box01:34:01
ramp from attribute and01:34:05
right to you yeah01:34:09
yeah so you can kind of see it's hard to01:34:10
see but01:34:12
um you can kind of see that that01:34:15
gradient01:34:16
like kind of wave right there that's01:34:19
what i'm looking for01:34:20
so that'll make that'll make a pretty01:34:21
big difference01:34:24
okay so we'll do01:34:27
save node type01:34:32
match current definition save this bad01:34:36
boy01:34:40
and run this one more time01:34:54
so that we can start to um build out01:34:57
the uh the look of our feather now01:35:00
uh while this is cooking what i'm01:35:01
thinking is i want because i'm having01:35:04
her be a raven01:35:05
and she's gonna be norse and uh so i'm01:35:08
thinking there will be01:35:10
like like it'll be like my feather01:35:15
will go like this01:35:18
and then these will be it'll be mostly01:35:20
black but then i want to have like01:35:23
something like this01:35:26
like that so i want all this to be black01:35:29
and i want this01:35:30
i think i want this to be gold01:35:34
like metal gold like so it looks shiny01:35:38
um but what i want is i want the uh01:35:41
the gold i want the01:35:44
the inside like i want this part01:35:48
to be very rough01:35:51
equals like point eight or something01:35:54
like that and then out here this part and i want01:35:57
to get shinier and shinier and shinier01:35:59
so the roughness out here will be like01:36:02
point01:36:04
one or something like that or 0.1 so the01:36:08
idea i think is is that01:36:10
how i'm thinking about this in my head01:36:13
is uh01:36:14
uh like the feathers like that if it is01:36:17
gold gold whatever and those things are01:36:19
rubbing up against each other01:36:20
those edges are constantly polishing01:36:22
each other right that's the story i'm01:36:24
gonna that's what i'm telling myself in01:36:26
my head those edges are constantly polishing01:36:28
each other and they're always gonna be01:36:29
very very uh very very smooth because01:36:32
they're constantly kind of like rubbing01:36:33
on each other like that and polishing01:36:34
each other01:36:35
and knocking off any dirt now as you get01:36:37
to the center of the feather there's01:36:39
less and less01:36:40
uh friction and so dirt will dirt and01:36:43
things will just kind of01:36:44
naturally accumulate water or whatever01:36:46
oxidation will01:36:47
naturally accumulate in that by that01:36:49
center spine and you'll get it won't be01:36:51
as01:36:52
as bright um so it'll just give us some01:36:54
some some variation01:36:55
overall um01:36:59
what else do i want to do this um01:37:05
oh the other thing i want to do is01:37:10
i want a randomized attribute01:37:14
per strand and that's really easy to do01:37:25
so i have01:37:32
here01:37:52
i'm going to do this here01:37:55
and i'm just going to do another color01:38:02
and this is going to be a constant but01:38:05
this is a01:38:06
just random oh no don't want to do that01:38:09
because that's going to color each01:38:12
primitive01:38:13
even if i do primitive it's going to01:38:15
color each primitive random so i want01:38:17
uh each uh chunk to be a random color so01:38:21
what i can do is instead of random i can01:38:24
do random from attribute01:38:26
and then i can do a connectivity01:38:32
let's put this to primitive actually no01:38:34
point01:38:36
and this will also be point01:38:42
delete and class01:38:45
so yeah there we go01:38:53
so do the same thing as you recopy01:39:00
two from i'm gonna copy cd01:39:04
and call this feather rand01:39:13
and then yeah so01:39:17
copy that and then just do the same01:39:19
thing over01:39:20
here with my01:39:25
curb base01:39:43
i'm not really using the curve base very01:39:44
much but i'm still building out because01:39:46
if i did want01:39:47
to you know eventually get super super01:39:50
close to this01:39:51
right or i wanted to have like millions01:39:53
of these and i was doing like a01:39:54
pre-render thing that i wasn't so i'm01:39:56
mostly just targeting for like i'm thinking01:39:59
about how how i would do this01:40:00
if i had to put this into some sort of01:40:02
real-time environment01:40:04
um so you can't put really put curves in01:40:06
well not yet um01:40:07
that's coming very very quickly but you01:40:09
can't really put curves raw curves and01:40:10
you can't put this much01:40:12
uh you can't put this much geometry01:40:15
into uh into a real-time environment yet01:40:18
um i mean there's uh with the unreal01:40:22
engine fives is the whole nanite system01:40:23
and that's only gonna grow but this is01:40:25
these are gonna be deformable by by01:40:27
definition feathers flex and bend and01:40:29
stuff so you can't01:40:30
you can't use you can't just throw01:40:31
millions of feathers into into the01:40:33
system and have them flex and move01:40:34
around or else it's gonna choke01:40:36
okay so that's feather rand uh cool01:40:39
yeah so let's go back out01:40:44
save no type01:40:48
and match definition01:40:52
save so if i come down down down down01:40:56
down to down to01:40:57
my hi-res i should have a01:41:01
feather rand so there's that01:41:13
yeah so there's my feather brand so i'll01:41:15
add that to my customs01:41:16
as well add01:41:20
f-e-a-h feather01:41:23
and01:41:29
okay so let's save this and actually you01:41:32
know what01:41:33
because i'm going to actually bake these01:41:35
out at like a bonkers resolution like 4k01:41:37
um because i'm not actually going to use01:41:39
these maps these maps are going to be01:41:41
used maybe the normal map but these maps are01:41:44
going to be used to um to generate my01:41:49
my my other maps so my normal map i01:41:51
might use directly out01:41:52
um but i'm probably gonna edit its like01:41:54
intensity like if i'm if i'm finding01:41:56
this moire pattern01:41:57
uh that's what these little lines are if01:41:59
i'm finding that's too intense i can01:42:00
i can knock that down in uh in substance01:42:03
designer01:42:04
so yeah so i want as much information as01:42:07
i can get01:42:14
uh so let's uh hit uh render and let01:42:17
this cook01:42:38
and i may even spit out by my um just do01:42:40
a quick01:42:41
fbx export of uh01:42:44
of uh of the whole feather so we'll go01:42:46
check the whole feather i'll throw a01:42:48
uv quick shade on it so we can see that01:42:50
checker happening01:42:51
on all of the uh all the proxy geometry01:43:07
the other thing i'm probably gonna have01:43:08
to do is i'm probably to have to01:43:09
actually texture that01:43:10
like the chicken wing that's on the01:43:12
inside as well and so01:43:13
uh i think uh substance assigner will be01:43:16
quite good01:43:17
um in that regard as well so i might be01:43:19
able to get uh use um01:43:21
use the uh flow map tools so we can we01:43:24
can examine those as well01:43:53
can i say the word hammond backwards01:43:58
no no i can't i don't even know what01:44:00
that means01:44:06
so this is this is cooking this is01:44:07
cooking this is cooking um01:44:09
dare i open substance designer01:44:17
no no streaming and houdini and01:44:20
substance designer may be a little bit01:44:21
too much01:44:22
so we'll just wait i just have to be01:44:23
patient learn to be patient and learn to01:44:26
wait for good things to happen to you or come01:44:29
to you01:44:31
i could have probably turned off uh01:44:36
probably turned off um uh01:44:40
ao that's taking a long time01:44:46
look i should be able to see my low-res01:44:49
and my high-res geometry01:44:51
look at my01:44:55
let's see do01:45:41
so let's see where is my high res01:46:00
oh there they are there are my01:46:03
high-res feathers there01:46:08
and then low-res01:46:19
about right there so i don't know01:46:23
it's very strange that they're they're01:46:25
tessellating like this but that's okay01:46:29
they're there01:46:35
oh already i can tell these look really01:46:37
really good01:46:46
look at that 4k 4k goodness01:46:50
up in there man that ao01:46:53
looks if that ao even looks great look01:46:55
at that01:46:59
yeah so this is that b box y i was01:47:00
talking about that i was that i was01:47:02
working on01:47:03
so if we come into here we can see now01:47:06
each strand is one so you can actually01:47:10
see the the overlap01:47:11
there it's very subtle01:47:16
but this strand is subtly darker than01:47:18
that one and so on and so forth so we01:47:20
can all it's almost like a depth pass you could01:47:23
look at it if you really want to look at01:47:24
it that way01:47:28
so that's really cool01:47:46
and the rest are still being written01:47:48
let's look at a01:47:52
mask it's looking really good01:47:56
it's really good overall um random01:48:07
that's looking really nice so what i can01:48:09
do with that random what i can do with01:48:10
this random01:48:11
is i can i can use that to modulate01:48:14
uh shininess from strand to strand to01:48:17
strand01:48:18
just adds a nice little bit of like01:48:19
non-computery01:48:21
uh ness while using computer units and01:48:23
then i have my opacity01:48:24
my feather position and my01:48:28
length u01:48:34
oh yeah that's beautiful that's gonna01:48:36
work very very nicely01:48:37
once we get that in so this will allow01:48:40
me to modulate like i said i want the01:48:42
the center to be less rough and the01:48:44
outside01:48:45
to be to be more uh no i want the center01:48:47
to be more rough01:48:48
and the outside to be less rough01:48:52
so i might just get away with just01:48:53
inverting inverting this01:48:57
and then my normal map01:49:01
yeah this is looking great01:49:06
so just let this finish i think it's01:49:10
doing position now01:49:15
i might actually hold off on doing this01:49:17
until until next time because this is01:49:18
just this is just finishing up01:49:20
uh finishing up uh um01:49:24
compositing but what i will do is what01:49:26
we can do is i can put a just like kind01:49:28
of like a uh01:49:29
uh like a quick material on this just to01:49:32
see what it'll look like in01:49:36
and uh yeah i think that'll be that'll01:49:38
take us to01:49:39
to to01:49:50
why this is taking so long01:50:20
stop messing with things bentley um so01:50:24
while this is uh doing whatever it's01:50:27
going to do01:50:32
those those maps right and01:50:37
it's a really powerful idea this this is01:50:39
zero to one01:50:41
right so if we look at that from the01:50:42
side01:50:44
right if we have01:50:48
let's blackboard this01:50:53
so let's say this is my01:50:57
so this is zero zero01:51:00
this is uh x is one y is zero01:51:04
and y right01:51:07
so this is black01:51:13
and this up here is white01:51:22
you have this line so this would be a01:51:24
straight gradient right so this would be01:51:26
um like if i were to do this in01:51:29
photoshop01:51:30
it would like be like really sparse and01:51:33
then it would get01:51:34
thicker and thicker and thicker like01:51:36
that right01:51:37
so um01:51:41
and this is what the the the curves uh01:51:44
tool is doing in photoshop so if i take at01:51:47
0.501:51:48
and go across here and i go at 0.5 we go01:51:51
across here01:51:53
missed right this point here01:52:00
should be 50 gray01:52:03
if i have a straight linear black to01:52:05
white now when i take01:52:07
if i go into my my curves node01:52:10
in photoshop or sub designer or sources01:52:13
painter or01:52:14
whatever basically what i'm doing is i'm01:52:16
pushing around this middle value so i01:52:17
can make01:52:18
this go like that01:52:22
right so now instead of 50 i'm at likeDescription:
