00:00:00
well good morning everybody sorry uh00:00:02
started a little bit late00:00:04
as usual technical difficulties00:00:07
occurring right at the00:00:08
moment of hitting stream um welcome i00:00:11
hope you're having a good00:00:12
uh weekend or maybe it's monday where00:00:15
you are00:00:16
um it's monday monday morning for me00:00:19
here in australia00:00:20
um today we're going to keep working on00:00:25
the tornado that i started last week00:00:28
i just actually it's the sharks that's00:00:31
right00:00:32
um hey audrey how's it going um00:00:36
yeah last last week i started setting up00:00:38
sunday evening oh nice00:00:40
i started setting up this tornado and00:00:42
just this morning00:00:44
um i wrote this out at00:00:47
a little bit higher resolution so we00:00:48
could see some details and it's looking00:00:50
pretty cool this this kind of tube00:00:53
here is not super great00:00:56
hello is it hardik how are you going00:00:59
welcome thanks for joining me00:01:01
um so this tube is a little bit kind of00:01:04
uniform i guess but it's not00:01:05
not too bad what i might do i think i00:01:08
wrote out00:01:09
about 400 frames so00:01:12
i'm just going to00:01:15
write this out to a flip book and we can00:01:17
see what we're dealing with so this00:01:18
resolution is not super high-res00:01:23
but it's pretty good yeah lots of lots00:01:25
of people joining today that's great00:01:27
hello everybody um let me know if you00:01:30
have any questions00:01:31
and uh welcome you know welcome to the00:01:33
stream i just realized i'm not sharing00:01:34
my screen00:01:35
um so you guys can't see what i'm00:01:36
looking at here we go so here's00:01:39
here's my um here's the sim that i wrote00:01:43
out this morning00:01:44
and it's written out at 0.07500:01:47
but for the scale that this is that's00:01:50
not00:01:51
super high resolution if you have a look00:01:54
here you can see 58 million voxels00:01:57
so it's kind of hey michael how's it00:02:00
going welcome00:02:01
um robert00:02:04
how are you doing getting in before work00:02:07
or00:02:08
watching while you're working00:02:12
um so yeah you know 60 million voxels00:02:15
it's really not that00:02:16
not that many um when it comes to like00:02:18
feature00:02:19
quality um resolution00:02:22
but it really depends on how far away00:02:25
our camera is from00:02:27
from the shot you know if we have a look00:02:28
at our kind of00:02:30
close-up camera obviously um watching00:02:33
while working nice00:02:34
i like it um that's a good thing about00:02:37
doing 3d that00:02:39
you can kind of watch things while00:02:41
you're working which is00:02:42
which is good um if you don't have to00:02:45
think too hard00:02:46
uh so yeah like at this resolution at00:02:49
this distance from camera00:02:50
this resolution would be fine but if we00:02:51
were right up close00:02:53
you know you might start to see some of00:02:54
these details become a little bit soft00:02:57
and fluffy and boxy00:02:59
so i think for this camera00:03:03
it's probably a little low resolution00:03:04
but you know for the purposes of the00:03:06
stream00:03:07
this is fine it's still relatively easy00:03:10
to work with00:03:11
so let's just do a little flipbook i'll00:03:13
zoom right out so you can see all the00:03:14
details00:03:16
and this is kind of the camera angle00:03:17
that we're going for00:03:19
and if we have a look at our original um00:03:22
line00:03:24
you can see oh that doesn't look very00:03:26
good that would convert00:03:28
you can see that we're still really kind00:03:30
of quite closely following that line00:03:32
position so our original00:03:34
kind of line is what's controlling and00:03:36
driving this00:03:37
um so let's let's have a look i'll do00:03:40
400 frames and00:03:43
just flip book that and that'll pop up00:03:46
and then play and let's have a look at that00:03:50
um hopefully i've noticed that my camera00:03:54
freezes when i'm doing anything kind of00:03:56
intensive so hopefully00:03:58
hopefully it stays okay but it's a bit00:04:01
annoying00:04:03
so it's a pretty slow simulation00:04:07
i slowed it right down to get the scale00:04:10
you know this is meant to be a really00:04:11
large00:04:12
event so by slowing it down it makes it00:04:14
feel00:04:15
a little bit larger it's probably00:04:17
arguably still a little bit fast00:04:20
but you know i don't want to have to00:04:21
simulate a thousand frames or just take00:04:24
too long00:04:26
so let's see you can see it building00:04:28
there you can see that kind of00:04:31
vortex taking over and spiraling that00:04:34
stuff around00:04:35
we're getting some pretty nice details00:04:36
happening probably a little bit thick00:04:39
and billowy on the ground00:04:42
but you know this is just a good good00:04:45
kind of bass line and that's the purpose of00:04:47
doing the flip book as well as just to00:04:48
see what what's kind of working and00:04:49
what's not there's some weird popping00:04:50
going on from the shadows00:04:52
that black kind of popping that's moving00:04:54
but that's00:04:56
that's not a problem that's just the00:04:57
viewport kind of stuff00:05:00
getting lots of nice details and the you00:05:03
know it's pretty thick in the viewport as00:05:04
well so we could also turn that down00:05:06
you know when we come to render make it00:05:08
a little bit nicer00:05:11
so just let it keep going00:05:15
it's pretty boring waiting for flipbooks00:05:16
but um00:05:18
you know it is a really good way to just00:05:20
see what we have to deal with and00:05:21
whether we need to make any changes00:05:26
i was going to look for an asset to00:05:28
destroy with this simulation but i think00:05:31
what i'm going to do is just build00:05:33
something that's going to be nice and00:05:35
easy00:05:36
to um to work with00:05:39
uh and also you know get the chance to00:05:42
show you guys some um00:05:44
some procedural kind of building00:05:46
creation it's not gonna be00:05:48
insanely detailed or anything it's just00:05:50
gonna be like a little shack00:05:52
but um you know sometimes when you use a00:05:55
model that you've bought or downloaded00:05:58
it can be a lot of work to get it kind00:06:00
of00:06:01
working right as an rbd simulation or00:06:03
something00:06:04
so it can take a lot of time to process00:06:07
that00:06:08
and it's sometimes better if it's a00:06:10
simple kind of asset a simple building00:06:12
even though it's time consuming to build00:06:14
on uh sometimes it's00:06:16
less time consuming to build one than to00:06:18
kind of00:06:20
re-engineer or reverse engineer one that00:06:22
you've downloaded00:06:23
um so yeah we'll have a bit of a look at00:06:26
that and then00:06:27
look at how we can pull that in to00:06:31
maybe rbds maybe a bit of vellum as well00:06:33
might be cool00:06:34
if we get some um like sheet metal we00:06:37
call it corrugated iron here00:06:39
it's like the kind of um ripple rippling00:06:42
metal that you have on00:06:43
tin sheds um maybe that00:06:46
know could be a cool thing to do through00:06:48
vellum where we get it kind of flapping00:06:50
in the wind and then tearing off that00:06:51
might be really nice00:06:53
um so00:06:57
yeah let's let's have a look so it's00:06:59
yeah i mean00:07:00
it's not perfect this tornado by any00:07:03
means i'm not super happy with how clean00:07:05
this kind of00:07:07
surface is here and i think it would be00:07:10
it would be much nicer if it was a bit00:07:12
more broken up um00:07:13
the density might be a part of that you00:07:15
know maybe taking the density down00:07:16
might help overall with that sort of00:07:19
solidness00:07:20
or perhaps we add an additional element00:07:24
uh can you tell me what we do today yeah00:07:27
okay so00:07:28
last last week i set this up heartache00:07:31
and00:07:33
it's because it's lacking cows says00:07:35
audrey yeah that's that's probably it00:07:37
it just needs a few cows in there um so00:07:40
last week we set this up and basically00:07:43
it's a tornado simulation that's based00:07:46
on a curve the curve is driving00:07:49
a kind of um a vortex basically00:07:53
and forces to get this to go in a00:07:54
particular shape and to get it to rotate00:07:58
uh so definitely you know after this one00:08:01
if you're interested in learning how i00:08:02
did that go back and have a look00:08:04
at how i set that up um00:08:07
and then today we're gonna just take00:08:11
this simulation and maybe add some extra00:08:15
simulations to this one00:08:17
and definitely take a look at how we00:08:19
could incorporate some sort of rigid00:08:21
body00:08:23
destruction and also maybe some particle00:08:25
simulations as well i'm gonna try and00:08:26
build it up into it00:08:27
you know into a nice shot um so there we00:08:30
go it's00:08:31
it's done so let's have a look00:08:35
and it's kind of different i guess to00:08:37
the way that tornadoes work00:08:41
in nature so that might be something00:08:43
that we need to go back and revisit00:08:44
where usually they start from the top00:08:46
down or they might kind of join or00:08:49
something in the middle00:08:50
need to look at some reference for that00:08:52
but most of the things i've seen they00:08:53
kind of00:08:54
seem to the funnel seems to start from00:08:56
the top um00:08:58
but yeah anyway that's that's kind of00:08:59
the that's kind of the plan00:09:01
i definitely think lowering the density00:09:03
might help uh rizwan says you need a00:09:05
tornado siren00:09:06
yeah i used to have a guitar pedal that00:09:08
had a siren function on it it was really00:09:10
annoying so i sold it but00:09:11
um i i could use it right now00:09:15
um so yeah let's let's have a look so00:09:19
let's let's drop the density first of all and00:09:22
just see i'll put down volume00:09:23
visualization00:09:25
and just set it to density00:09:28
and then we can see what it looks like00:09:30
with a bit less00:09:32
kind of density and it's a bit less kind00:09:36
of you know solid looking but also when you00:09:38
decrease density you also kind of lose00:09:40
some of the details which can be really00:09:41
nice00:09:42
um the other thing that is worth doing00:09:46
to check your kind of um camera two is00:09:49
right in the action um the other thing00:09:52
that's worth doing just to check what00:09:53
your details are kind of looking like is00:09:56
you know maybe we'll go with something00:09:57
like this so we can see a good chunk of00:09:59
the top as well create a new camera00:10:01
and just render it so so that we can00:10:04
kind of get an idea of what those00:10:05
details look like because00:10:07
i think as of hey see robert thanks for00:10:10
joining me00:10:11
um i think yeah because the viewport00:10:15
down samples00:10:16
volumes it's a good idea to render it00:10:18
out so you can see the full resolution00:10:21
you can change that if you hit d in the00:10:23
viewport and go to texture00:10:25
you can change the 3d textures limit00:10:27
resolution00:10:29
so be higher but i find that you know my00:10:33
viewport performance starts to really00:10:34
chug00:10:35
and it gets super slow so rather than00:10:39
doing that i like to just render because it's00:10:42
faster so go to the render view we've00:10:45
got an ipr render here let's just have a00:10:47
look at what we've got visible00:10:49
uh we've got only one object which is00:10:52
good and we've got a spotlight so let's00:10:53
set that to camera three the one we just00:10:55
created00:10:56
and we'll hit render and it should be00:10:59
relatively fast00:11:02
looks like last week we kind of i did00:11:04
some stuff in here i can't remember00:11:06
doing a render but maybe i did00:11:08
um and there we go so it's pretty fast00:11:11
because00:11:12
we only have a single spotlight and00:11:15
our render settings are not overly high00:11:17
they're just the default kind of00:11:18
settings00:11:19
the spotlights usually render relatively00:11:21
fast it's only 22 seconds00:11:25
and i don't know if we have a material00:11:27
on here let's see00:11:29
i didn't create a material but actually00:11:30
what you get out of the pyro solver00:11:33
if you have a look middle click you can00:11:34
see it actually comes with a shot00:11:36
material path00:11:37
so it's got a material built in00:11:40
and when you are on the pyro solver and00:11:43
you're tweaking these look00:11:45
settings they both control how it looks00:11:47
in the viewport but they also set00:11:49
the material properties but since we've00:11:52
cached this to disk00:11:53
i'm just going to create a new material00:11:56
and00:11:58
anyone that you know was was one of my00:12:00
students00:12:01
would have known that i like creating my00:12:03
own00:12:04
materials for volumes i like to create00:12:07
nice simple ones because00:12:08
the pyro shader is00:12:11
overly kind of bloated and00:12:14
complex for just a very simple density00:12:17
shader but i00:12:18
i even like creating my own fire shaders00:12:20
as well00:12:21
i can just make them nice and simple00:12:23
have exactly what i need00:12:25
and yeah i just find it easier so00:12:28
what you need is a compute lighting node00:12:32
and you can hook up c f o f00:12:35
and f and then in this layer input here00:12:38
we're going to put00:12:39
a volume shader core00:12:43
there's actually two that you could use00:12:45
volume shader core or pyro shader core00:12:48
the pyro shader core is occasionally00:12:49
slightly more useful because it has00:12:52
this smoke brightness setting which the00:12:55
volume shader doesn't00:12:56
so you can actually lift the brightness00:12:58
of the smoke which which sometimes yeah00:13:00
i find really useful00:13:01
so um maybe i'll use the pyro shader00:13:03
core00:13:04
they've got yeah a couple of just extra00:13:07
things for fire as well not that we're00:13:08
going to be using fire but um let's use00:13:10
pyro00:13:11
shader and then we've got this density00:13:14
input here so we're just going to bind00:13:16
the density field and plug it in so00:13:19
density00:13:21
into density and then we don't have a00:13:24
multiplier for00:13:26
the smoke or the density here so we need00:13:29
to add one here00:13:30
multiply i think maybe that's the00:13:33
difference of the volume00:13:34
shader core the volume shader core has a00:13:37
density scale but the pyro shader chord00:13:39
doesn't00:13:40
weirdly i don't know why actually let's00:13:42
just use this one00:13:44
so it'll be easier we don't we don't00:13:46
really need the pyro one00:13:48
so i'll get rid of that use volume00:13:49
shader and then i can just go okay00:13:51
density 1000:13:53
and that's kind of it that's all i need00:13:54
to do for this shader compute lighting00:13:56
volume shader00:13:57
bind density and i'm just going to call00:14:00
this00:14:01
simple dust let's see if i can drag it00:14:05
on there i don't think that'll update00:14:06
because00:14:07
even though that probably worked you can00:14:09
see that material has been populated by00:14:11
dragging it onto the render view00:14:13
it's not working because there is a shop00:14:16
material path attribute00:14:18
so i just need to delete that00:14:23
primitive attribute shot material path00:14:25
and now we should see some change00:14:26
although the setting i gave it of 10 is00:14:29
actually the same00:14:30
as what this is it's probably going to00:14:31
look exactly the same00:14:33
let's just change the color and then00:14:34
we'll see hopefully something change00:14:37
there we go pink tornado fairy floss00:14:40
um so let's give it a kind of you know00:14:43
dusty00:14:45
tone maybe a kind of de-saturated00:14:50
brownie kind of color00:14:56
maybe two two brown00:15:00
all right so there we go00:15:06
i just had an idea one thing you might00:15:08
be able to do which could be interesting00:15:10
because because this is all just one00:15:11
tone00:15:13
um and that's that's the problem we00:15:15
thought of pyro sims is that they are00:15:17
all just one00:15:18
color unless you simulate with a color00:15:19
field but we haven't done that00:15:21
but what we could try and do is00:15:23
something interesting like00:15:25
um maybe let's see how high this thing00:15:28
is00:15:29
just go back out to our scene view00:15:33
and we've got roughly 25 meters here so00:15:36
zero to 2500:15:38
if i go back to my material and you can00:15:41
see here i've got these globals and00:15:42
here's p00:15:44
if i put a vector to float down00:15:47
and plug that into p and then here's my00:15:50
y component which is my height00:15:53
if i put a fit in there like that00:15:57
and get rid of that color fit between 000:16:00
and 2500:16:02
and i'm basically going okay what was00:16:04
zero is still00:16:05
zero but what was 25 is now outputting00:16:07
one so i've essentially normalized that00:16:10
kind of range from there to there00:16:12
and then if i put that through a ramp00:16:16
a color ramp and run that into smoke00:16:20
color00:16:22
let's see what happens00:16:25
i'm gonna go infrared00:16:31
and i'm getting some fading although the00:16:34
range00:16:35
is kind of different you know what i00:16:36
think when you're working in material00:16:39
uh in surface context you need to put a00:16:42
transform down00:16:45
on your world positions and it00:16:49
transforms it00:16:50
from the kind of world space into the00:16:52
rendering space and now you can see00:16:55
that i got my purple down here which is00:16:57
kind of representing00:16:58
zero value and then right up the top00:17:01
around 25 i've got red00:17:02
and now you can see i've got a nice kind00:17:04
of rainbow00:17:06
shading it's very screen space kind of00:17:09
you know top to bottom00:17:10
but what it will allow me to do is just00:17:12
go kind of00:17:14
you know maybe i'll take this color that00:17:15
i decided on here00:17:17
and i'll put that put that in here00:17:20
paste values i'll get rid of all these00:17:23
maybe towards the top i can make that a00:17:25
bit whiter00:17:26
oops00:17:30
like that and i can kind of create this00:17:33
gradient00:17:36
of color which means i could maybe make00:17:39
the00:17:40
stuff down the bottom look a bit more00:17:41
like dirt a bit more dusty but then as00:17:44
it goes up higher00:17:45
it starts to you know take on a00:17:48
different00:17:49
kind of color so that's a really00:17:52
interesting way of kind of00:17:54
changing the color it is very kind of00:17:55
just height-based00:17:57
so it's not perfect but it's an00:18:00
interesting way of just getting some00:18:02
variation00:18:03
in your simulation00:18:06
post simulation this is just a render00:18:08
time thing you know so i'm not actually00:18:09
doing anything in the simulation really00:18:13
and you could make those kind of you00:18:15
know00:18:17
the the bigger those kind of adjustments00:18:19
are or the you know the less kind of00:18:21
steps you have the more gradual it will00:18:22
be and the more kind of realistic maybe00:18:25
uh what what would be ideal is if you00:18:27
actually simulated with color and we00:18:29
could potentially look at that at some00:18:31
point so that you get mixing of colors and00:18:33
then it's not just so linear00:18:35
um but this is a kind of nice you know00:18:38
just00:18:39
hack little tweaky thing that we can do00:18:41
now another thing we can do is we've got00:18:43
really dark shadows here00:18:44
so one thing we could do on the shader00:18:46
just to make it feel a bit more00:18:48
um i guess illuminated through like the00:18:51
light is scattering through the object00:18:53
is to just drop the shadow density scale00:18:56
and you can see that that just reduces00:18:59
the darkness of the shadows00:19:01
how much ram do i have good good00:19:03
question um00:19:05
i'm very happy to uh to tell you that i00:19:08
have00:19:09
gig but this has only been a recent00:19:12
thing i just00:19:13
i upgraded uh recently because the00:19:15
projects that i've been doing00:19:16
at home have uh have really increased in00:19:19
their complexity00:19:21
uh prior to that i had 32 gig and00:19:24
as people that have been watching the00:19:26
stream for a while no00:19:28
i i did crash during one of my streams00:19:31
um00:19:32
which was you know bad it was00:19:33
catastrophic my computer shut down00:19:36
so i could still do this on 32 gig but i00:19:39
i do have to kind of00:19:41
really watch how hard i push things00:19:45
um and it kind of limits the amount of00:19:46
multitasking that i can do and so00:19:50
it is amazingly good to have 128 gig but00:19:53
you don't need it00:19:54
um it does make it better and you don't00:19:56
have to worry as much about00:19:58
about tapping out um but00:20:01
yeah you you know uh look00:20:04
yes eight gig you will kind of hit00:20:08
some some some of those limits a lot00:20:10
sooner00:20:11
um you can do things on eight gig you00:20:14
just won't be able to do00:20:16
the complexity you know that that i00:20:18
could do00:20:19
on 128k but for example i i was working00:20:22
on a laptop for a long time00:20:24
at home and that only had 16 gig00:20:28
and i was able to do you know lots of00:20:30
really cool stuff00:20:31
on 16 gig i did hit those limits very00:20:35
you know very kind of quickly um but00:20:41
that's right if it catches fire it's00:20:42
time to consider getting more00:20:44
it's yeah i mean if if you're constantly00:20:47
hitting it and you're00:20:48
crashing that's when i would choose to00:20:50
upgrade00:20:51
but if you're finding the things that00:20:53
you're doing00:20:55
on eight gig are working fine it depends00:20:58
what you're doing if you're doing lots00:20:59
of pyro simulations00:21:00
eight gig is not a lot and you you know00:21:03
you potentially will hit that00:21:05
frequently um but yeah00:21:08
i think just it really depends what you00:21:11
want to do so i would just use it00:21:15
and see how you go and if you're hitting00:21:16
the limit upgrade00:21:19
don't go to 128 straight away you don't00:21:21
need that it's very expensive00:21:23
but just kind of you know00:21:26
just kind of step it up as as you need00:21:28
it00:21:30
but i find working with less ram00:21:32
actually teaches you00:21:34
to be more efficient with your setups00:21:36
and to be00:21:37
a bit more kind of careful about what00:21:40
you're doing whereas you know with 128 gig i can just00:21:42
go yeah sure whatever00:21:44
you know and and it doesn't make me00:21:47
you know kind of good efficient artist00:21:50
i can just throw whatever i like in it00:21:52
but then if i give it somebody else it00:21:54
has less ram00:21:55
and they're like i can't open this thing00:21:56
it's ridiculous you know this resolution00:21:58
is crazy00:21:59
um so yeah it's good to be mindful of00:22:02
that as well and i find that it's kind00:22:04
of good to have less ram00:22:06
sometimes when you're learning because00:22:08
it teaches you00:22:10
to work within the limitations um00:22:13
when you're working at studios you don't00:22:14
always have 128 gig of ram some00:22:18
you know some places just don't have00:22:20
that um00:22:21
and you kind of have to just adapt to it00:22:24
and they demand still the same00:22:26
quality that you you know you would do00:22:28
on a bigger machine00:22:29
but but you just have to work within00:22:31
those limitations so00:22:33
yeah it's a good good thing to learn um00:22:35
so one thing i'm going to do here00:22:37
is i'm just going to pause this render00:22:39
for a second00:22:41
because those shadows are still quite00:22:42
dark even with a shadow density00:22:44
of 0.200:22:48
i'm going to add in a second light here00:22:50
so here's my camera00:22:52
so over here so let's say that this is00:22:54
my key light00:22:55
in fact i might swing my light around00:22:57
the back00:22:59
let's do that first let's move this00:23:00
light i'm going to swing it00:23:02
here's my camera's over here i'm going00:23:04
to swing it around00:23:06
here let's see what that looks like00:23:10
i want to create a nice kind of dramatic00:23:13
lighting00:23:14
like maybe high contrast or just have00:23:16
some really kind of nice00:23:18
illumination to show off the details of00:23:21
this simulation00:23:25
and maybe make it like a little bit more00:23:27
stylized as well00:23:28
maybe i'm not going for super realism00:23:30
here maybe it's just a super00:23:31
super kind of stylized shot so00:23:35
yeah i could go a little more swing it00:23:38
swing it right around the back like that00:23:43
so you see with the back lighting you00:23:45
get this kind of nice illumination of00:23:46
the edges00:23:48
and then you get this very high contrast00:23:50
kind of effect at the front00:23:52
it's very dark so what we could do is00:23:56
now put in a fill light so we've got00:23:59
this light over here which is creating this00:24:02
immense shadow on the front but if we00:24:04
put in a second light over here00:24:06
control click spotlight you can see that00:24:09
that fills in those shadows but what i'm00:24:11
going to do00:24:12
is drop the exposure00:24:15
so it's not filling them in completely00:24:17
but it is still illuminating a little00:24:19
bit so it's not completely00:24:20
black so you can see that00:24:23
there00:24:27
so these two lights you know i would00:24:28
call key00:24:30
oops key and fill00:24:37
so you can still see very subtle details00:24:39
there it's no longer00:24:41
just pitch black so it's kind of cool00:24:45
now let's uh what are we going to do00:24:48
next00:24:50
let's start building our a little shack00:24:52
in there and try and work out what scale00:24:54
this is so really00:24:58
the scale you know this thing should be00:25:01
ginormous and i do have uh00:25:03
i've got my tommy's in here let's get00:25:05
tommy and see00:25:07
see how big this thing is compared to00:25:08
the tommies that i created00:25:11
where is he there he is so00:25:16
where is that little tommy there he is00:25:18
there00:25:20
tiny tiny little guy00:25:24
so let's build a shack kind of based on00:25:26
his scale and i don't think i00:25:28
i don't think i touched his scale oh i00:25:29
did i scaled him down00:25:31
so let's let's let's build it based on00:25:34
his scale00:25:35
so i'm just going to build a box here00:25:40
and you can see this box you know if00:25:42
we're looking at houdini units this box00:25:44
is a meter by a meter00:25:45
but because i scaled tommy down to kind00:25:47
of make the00:25:49
uh tornado feel bigger i'm going to do00:25:52
the same with this so this is not going00:25:53
to be a meter and a meter meter by00:25:55
meter it's gonna be it's gonna feel much00:25:58
bigger00:25:59
so i'm not really worrying about the00:26:00
scale of the units00:26:02
let's just where's our tommy00:26:08
actually i might build it at world zero00:26:10
rather than building it off00:26:12
axis which is always a pain so i'm gonna00:26:15
build at world zero and then move it00:26:16
where i need to be00:26:17
so here's my tommy at world zero00:26:25
so we're looking at about point00:26:28
point four is now equivalent to whatever00:26:31
he is one point something meters00:26:34
so let's go yeah something like that00:26:37
maybe it's a barn or something it's got00:26:38
got high roofs so make it a little bit00:26:42
bigger00:26:43
yeah something like that00:26:47
all right let's go perspective view00:26:54
okay that'll do so let's have a look at00:26:57
that00:26:58
in relation to our tornado00:27:01
i'm just gonna put transform down here00:27:04
so i always00:27:05
block things out like this instead of00:27:06
just going in and trying to make a00:27:08
building straight away00:27:09
i always try and figure out you know how00:27:11
this is going to work with our00:27:13
scenario because we've got to kind of00:27:16
you know get it in the right place see00:27:18
what our tornado is doing so00:27:20
our tornado is kind of moving across and00:27:24
forming like this it's not moving very00:27:25
fast but it is kind of moving across00:27:30
and is it going to get into the path of00:27:33
this00:27:34
it almost does so it might it might kind00:27:37
of start to pull that00:27:38
off but let's just let's push it in a00:27:41
little further00:27:44
into here oh and i just realized it's00:27:46
really slow and maybe it was rendering00:27:47
oh no00:27:48
it's just the huge volume in there00:27:50
that's making it slow00:27:53
so we just kind of want to work this out00:27:55
for the shot00:28:02
it would probably be a bit cooler if00:28:03
there was a bit more you know kind of00:28:05
travel in this before it got to the00:28:07
house but00:28:10
maybe we could change our00:28:13
change our camera as well it doesn't00:28:15
have to00:28:17
doesn't have to stay there00:28:20
let's see00:28:27
yeah it might be kind of cool maybe just00:28:29
pull it out a touch00:28:34
and of course we can always change the00:28:35
scale of our building00:28:37
you know after we've made it we can00:28:38
scale it up and down if we need to but00:28:40
just trying to work out a good base00:28:41
scale00:28:42
all right i think that that will00:28:45
probably00:28:46
work pretty well so let's let's go and00:28:49
have a look at our building now i'm just00:28:50
going to00:28:51
just going to copy this i'm going to00:28:52
build it down here00:28:54
out of the way and here we go here's our00:28:58
building00:28:59
so first thing i'm going to do is build00:29:02
a frame00:29:03
i'm going to start by placing some boxes00:29:05
around and this this kind of serves as00:29:06
my template00:29:08
but i'm going to place00:29:11
some boxes around00:29:14
for the frame so this is going to kind00:29:16
of be the vertical so let's go maybe 0.100:29:19
by 0.1 just keep it all uniform raise it00:29:22
up00:29:24
template actually probably00:29:27
zero five by zero five from looking at00:29:29
the scale00:29:32
okay so to get this box to sit perfectly00:29:34
on the ground i'll just copy the height00:29:36
and paste relative reference divide by00:29:38
two00:29:39
and that will always no matter what um00:29:42
no matter what i scale this now it'll00:29:44
always sit on the ground00:29:47
now if i move this to one side00:29:50
and use the copy copy and transform node00:29:54
i'm just going to transform this00:29:58
across and by increasing the number i00:30:01
can create00:30:02
a nice kind of procedural frame so00:30:06
let's go like that doesn't have to00:30:07
perfectly match the box that we created00:30:09
so there we go and then if i take that00:30:12
actually i don't need to do another copy00:30:14
i can just do a transform like this00:30:18
and just even it's 180 that00:30:24
and merge it back with our original00:30:28
there we go so we've got two sides now00:30:32
and now we can do you know some cross00:30:36
beams maybe let's just duplicate this00:30:37
one00:30:39
and break that and rotate it00:30:43
by 9000:30:46
okay and now we could do00:30:51
what's like x and then pull out like00:30:55
this00:30:58
like this00:31:03
okay move down00:31:07
now because i know the end goal of this00:31:10
is going to be00:31:11
rbds i need to make sure well it's00:31:14
important to00:31:15
kind of keep things non-intersecting so00:31:17
just00:31:18
when i'm doing this i'm going to just00:31:21
sort of position it00:31:23
look at front view or00:31:26
was it front views 4 i think there it is00:31:29
so just look at that position and just00:31:32
sort of butt it right up against but not00:31:36
not through it and that will then00:31:40
you know be constrained so we'll00:31:41
constrain that on let's run another copy00:31:44
here00:31:45
and instead of traveling that way i'm00:31:48
going to00:31:49
travel upwards00:31:52
there we go00:31:56
so the cool thing about doing it this00:31:57
way is i can adjust these later if i00:31:59
want to00:32:01
change the height you know do all sorts00:32:04
of things like that looks like i need to00:32:05
change my00:32:06
original length so i'll just pull that00:32:09
out00:32:10
like that and00:32:13
we could also make this one smaller so00:32:15
you know it's a bit00:32:16
less of a um chunky00:32:19
beam it's not kind of exactly00:32:23
you know how you would build something00:32:24
but it's kind of yeah it's kind of going00:32:26
to be fine for what we need00:32:28
and then again we could rotate this00:32:29
around or in fact what we could do is00:32:32
merge this in here with this side so we00:32:35
kind of build a whole side00:32:38
first so like that and then we do our00:32:41
rotation so it rotates the entire00:32:43
kind of side so we're basically creating00:32:45
a mirrored building00:32:48
so we might do that right at the end00:32:52
okay now cladding so the good00:32:55
the thing that you kind of keep in mind00:32:57
when you're doing these things for rbds00:32:58
is like00:32:59
how many pieces do you want do you want00:33:02
lots lots of pieces in your simulation it00:33:04
looks better if things break up into00:33:06
lots more pieces so instead of just00:33:08
doing big long boards and probably these00:33:10
these big long ones as well could be00:33:12
shorter00:33:13
but instead of doing big long weather00:33:15
boards i'm going to just do really short00:33:17
weather boards00:33:18
so take this one here and00:33:21
i'm going to pull it down like this00:33:28
and let's just zoom it right out like00:33:31
that there we go00:33:34
and then i'm actually going to rotate00:33:35
this one here00:33:37
let's just template that and pull it out00:33:40
like this so it's going to be on an00:33:41
angle00:33:45
probably make it quite thin00:33:49
let's check00:33:53
just set it flush against let's move it00:33:55
right down00:33:58
and then00:34:02
change the angle a little bit there we00:34:03
go and then when i do a copy on this one00:34:11
you'll see i get that kind of00:34:12
weatherboard effect00:34:15
and actually if i change the original00:34:17
angle a little bit more00:34:19
and try and get them overlapping better00:34:21
without intersecting00:34:27
and then drop that down there we go00:34:29
something like that00:34:30
should work pretty well go up00:34:35
like that00:34:41
and then we can copy across as well so00:34:46
zero that one and then go across00:34:56
leave some gaps or we could just have00:34:57
those but right up against each other00:35:02
something like that would be fine00:35:06
and then almost makes it so let's00:35:10
let's just extend our weather board a00:35:12
little bit so that we fill that gap00:35:14
now one thing you can do with these to00:35:15
make this slightly more procedural is to00:35:17
take actually the00:35:19
the proper length and put it into the00:35:21
copy so00:35:23
the height is fine but i'm going to00:35:25
increase the length of this box here00:35:30
like that until it meets the edge here00:35:32
so you can see00:35:33
as i take that down there we go it meets00:35:36
the edge although00:35:37
actually probably i don't need to go00:35:39
that far00:35:40
because it will kind of overshoot as i00:35:42
adjust this but what i can do is take00:35:44
this here00:35:45
copy and paste it into the translate as00:35:49
a relative reference00:35:50
and then you can see that it's going to00:35:53
offset by the appropriate amount and00:35:55
then i come back here and adjust this00:35:58
and you can see it's perfectly adjusting00:36:00
the copy and transform00:36:03
based on the scale so i'm adjusting the00:36:05
scale here but it's also adjusting the00:36:06
transform00:36:08
so there we go00:36:12
that's not too bad00:36:19
it's pretty good we could probably go up00:36:20
one more as well00:36:24
maybe and then again00:36:28
you know we can merge all that together00:36:31
with this00:36:33
like that into our transform to get it00:36:36
onto the other side00:36:37
and then we've got two walls so that's00:36:40
pretty good00:36:41
let's now go and00:36:44
have a look at what else we could do so00:36:47
we're gonna build00:36:48
uh we're gonna build a roof so00:36:51
something to uh with lots of panels on00:36:53
it they can get00:36:54
get sort of torn off so let's00:36:58
first what i'll do i think is00:37:02
take one of these boxes00:37:06
and just start laying it kind of across00:37:10
so i'll move it up here rotate it around00:37:18
whoa it's a bit weird sometimes working00:37:21
in the viewport you grab the wrong00:37:23
hand or you grab two and you get some00:37:25
weird kind of results00:37:27
but let's just do something like this00:37:40
so you know very quickly you can start00:37:42
to assemble00:37:43
a procedural building that's going to00:37:45
work really well actually i'm going to00:37:46
sit this inside00:37:48
so it sits on the frame here it's going00:37:50
to work really well as a kind of00:37:51
destruction and then we're going to set00:37:54
up constraints as well so we can00:37:56
constrain all these things together00:37:57
because00:37:58
at the moment what's going to happen is00:38:00
that they're all just going to you know00:38:01
if we just run this through00:38:02
rbd simulation and we'll we will we'll00:38:04
check it see how it's00:38:06
performing but if we run it without00:38:09
any00:38:12
any constraints it's just going to00:38:13
collapse in a heap00:38:15
so constraints are what's going to make00:38:17
this kind of00:38:18
a bit more interesting and you know00:38:20
there's probably too many00:38:22
poles there but it's going to look00:38:24
better if we have more so00:38:26
i think i'll just leave that and this00:38:27
one isn't going to run through the00:38:28
transform so i'm just going to merge00:38:30
this one00:38:31
through like this uh00:38:34
there we go so now we've got a kind of00:38:36
um00:38:37
ceiling and then we're going to do some00:38:39
roof trusses i guess so00:38:42
let's again copy a box00:38:45
just template the ceiling and now i'm00:38:48
going to rotate00:38:52
and create some kind of frame here00:38:56
for the roof as you can see i'm00:39:00
i am no builder um but00:39:04
it is kind of you know it is kind of00:39:05
good to try and follow00:39:07
um building principles as00:39:11
much as possible it doesn't have to be00:39:13
perfect but00:39:14
you kind of want to you kind of want to00:39:16
give the illusion that this thing is00:39:17
real and has been constructed so00:39:20
having those things like trusses and you00:39:22
know all the kind of00:39:23
things that you might find in a building00:39:25
now we can just copy this copy here and00:39:28
then we've got that these are all pretty00:39:30
chunky so we might00:39:32
might need to just adjust some scale00:39:35
maybe00:39:37
that's the cool thing about the copy is00:39:38
we only have to do it on one00:39:42
let's make these a bit thinner and00:39:44
actually what we'll do00:39:45
with these i don't want them to00:39:48
intersect but00:39:50
i'm gonna have them like overlap like00:39:52
that or something00:39:58
just rest on there00:40:02
there we go that might be cool all right00:40:04
so let's00:40:05
let's run this through the rotate00:40:07
because this one is going to be a00:40:09
mirrored00:40:11
function so there we go jump back00:40:18
every architect would be proud until00:40:20
until you know we00:40:21
try and make this stand up and it falls00:40:23
in a heap death trap00:40:25
uh all right let's get a i can't00:40:27
remember what that's called the center00:40:29
center post oh look out our rotation00:40:32
actually00:40:33
has done not a great thing where it's00:40:35
created an offset00:40:36
probably because this is slightly offset00:40:38
from the world you can see that there00:40:41
here's the world and here's the start of00:40:43
the beam so it's actually kind of00:40:45
uh flipped it which is right but it00:40:48
hasn't done a great job of it so let's00:40:50
mirror00:40:51
instead let's see if mirroring actually00:40:53
works better00:40:55
um direction is said00:41:00
yeah that's right maybe i should offer a00:41:01
service for uh for architects00:41:04
destroy your building design while you00:41:07
wait00:41:08
um so there we go that works better the00:41:11
mirror00:41:12
although one thing with the mirror00:41:14
sometimes it flips normal so you do have00:41:15
to be careful with that00:41:17
uh okay so let's put a kind of central00:41:21
especially if it's filled with sharks00:41:23
that's right that will be the00:41:25
the pista resistance um00:41:28
so yeah let's let's put a00:41:32
big kind of center piece in there00:41:37
just to hold everything up another merge00:41:41
so you know if you're not familiar with00:41:43
modeling in houdini this is the kind of00:41:44
way00:41:45
i mean really i'm just placing boxes00:41:47
around here so i'm not really using too00:41:49
many modeling tools00:41:50
but um you know this is the way your00:41:52
model kind of ends up looking a bunch of00:41:54
mergers and lots of different operations00:41:57
and then00:41:58
you know you can collapse that down if00:42:00
you want to into a subnet00:42:03
um but it's it's really handy because i00:42:06
can go back at any point and00:42:07
access any one of these you know little00:42:10
setups and make an adjustment if i need00:42:11
to00:42:13
okay so let's do this nice big long one00:42:16
in the center oops00:42:20
like that some of these long pieces will00:42:23
probably need to fracture00:42:25
because you don't want this big long00:42:28
beam flying around it'll just be too00:42:30
too big so let's do something like this00:42:34
and then what we can do now is actually00:42:37
do our first little bit of00:42:39
actual proper modeling which is just to00:42:41
pull these00:42:44
pieces in line for the top00:42:47
so what we could do there is just put an00:42:50
edit down00:42:52
before the copy because we're just going00:42:53
to edit this one box00:42:56
and let's just hit the select00:42:59
where's our there it's there so i'm00:43:02
gonna set it to points00:43:04
select this point here transform00:43:07
and just move it up i'm gonna try and00:43:10
maintain00:43:11
the thickness all the way through00:43:15
and you can see because i'm mirrored00:43:17
that's happening on both sides00:43:19
i want to make sure that i'm not00:43:20
intersecting00:43:23
the escape have a look at that copy00:43:27
you can see it's done for all of them00:43:30
just a very small change has made that00:43:32
you know work a lot better00:43:33
we could do the same thing down here if00:43:35
we wanted to sit those on there or if we00:43:36
wanted to adjust this but i think that's00:43:38
that's kind of okay and there we go00:43:43
it's starting to look like a you know00:43:47
some sort of simple building farm00:43:50
building00:43:51
now let's get some roofing on there so00:43:53
for the roofing i'm going to00:43:55
use um probably what i'll do00:43:58
is start with just grids00:44:02
and the reason being i was thinking you00:44:04
know maybe i'll make some corrugated00:44:06
iron and and have have that corrugation00:44:09
in there and i will do that but00:44:11
first of all i'm going to base it on a00:44:14
grid00:44:16
because i'm thinking when i come to the00:44:17
simulation and that's why it's always00:44:19
good you know to think about the00:44:21
simulation when you're doing00:44:22
this i don't really want to simulate00:44:24
with a high-res00:44:25
kind of corrugated00:44:28
metal or a corrugated model because it's00:44:31
going to be quite00:44:33
you know quite a lot of polygons and the00:44:36
less polygons you have to deal with00:44:38
the better so let's00:44:42
place that we can check the angle00:44:44
because we've set the angle on this one00:44:45
we can actually copy that00:44:46
minus 38 there we'll copy this whole00:44:48
thing actually00:44:50
copy paste oh no just that one looks00:44:53
like we need00:44:55
sort of that one there copy parameter00:44:58
paste values and then that will be the00:45:00
same angle00:45:02
we could make that a relative reference00:45:04
if we really wanted to00:45:06
but i don't think we need to go that00:45:07
crazy00:45:09
and then let's make this00:45:13
on the roof but i'm not going to do the00:45:16
full length for each one because again00:45:18
i i like this to be in lots of different00:45:21
sections so we see that00:45:23
okay and let's make it kind of00:45:27
the width of one of those00:45:30
separations so let's go down here we'll00:45:32
put it00:45:34
like that and copy and transform again00:45:39
copy and transform00:45:43
and we're going across actually we're00:45:45
going negative x00:45:46
so let's take our width here's our long00:45:50
width here00:45:51
copy we're going to paste that in x00:45:54
space really reference but actually it00:45:55
sends it the wrong way00:45:59
and yeah it's a little bit it's not00:46:00
quite right actually uh oh actually i00:46:02
grabbed the wrong one00:46:03
i grabbed the height i want this one00:46:06
pasted really referenced but it's00:46:07
actually sending it the wrong way00:46:09
because i placed it kind of um00:46:13
in the positive x and i need to send it00:46:15
down negative00:46:16
so what i can just do is just multiply00:46:19
that by a negative one and it will send it00:46:21
the other way00:46:23
okay so we've got our kind of00:46:28
grid's going it's not quite meeting this00:46:29
end one so that's a little bit00:46:31
interesting let's create a little offset00:46:32
here so you could even add00:46:34
um so let's put a plus in here first so00:46:38
we'll offset00:46:39
0.1 and then so we'll put all of that in00:46:42
brackets and then times it by negative00:46:44
one00:46:45
so point one is too much 0.0100:46:52
well thank you for uh thank you for00:46:54
enduring this uh00:46:56
this journey through procedural modeling00:46:58
audrey00:46:59
um grabs one i don't even know what i00:47:03
did i can't remember00:47:04
um so it looks like the00:47:08
i guess the width is kind of different00:47:10
so the offset is00:47:11
getting worse and worse as we go down or00:47:15
it's worse towards the center and that00:47:16
starts to come good again00:47:18
so i'm not sure what not sure what i've00:47:20
done there but00:47:21
maybe let's just try and adjust00:47:26
see if we can make it work00:47:32
it's so weird i guess it doesn't really00:47:34
matter00:47:35
let's let's not create the offset let's00:47:38
leave the offset off00:47:41
it doesn't really matter that it you00:47:43
know it's overlapping or00:47:44
that it doesn't quite line up to these00:47:46
panels um00:47:47
so take that down and then i'm going to00:47:50
move this over so it's overlapping there00:47:56
there we go so00:48:00
we got our panels there and let's now00:48:05
probably what i'll do is let's see00:48:08
if i put another copy and transform00:48:14
i'm going to just shift this00:48:17
down so down and00:48:21
across like this actually that might be00:48:25
a little bit tricky so let's00:48:27
let's try because we've got this we've00:48:29
got this control here for the grid so i00:48:31
might just00:48:32
actually duplicate the grid create a00:48:35
second whoops00:48:37
pick transform only just create a second00:48:40
one here00:48:41
like that that might work better we00:48:44
could even make this one slightly00:48:46
smaller00:48:50
put another copy on there and then just00:48:53
just duplicate this whole thing and do00:48:56
the last one like this00:49:01
line it up oh00:49:07
what am i animating uh i'm not animating00:49:10
anything donald uh thanks for thanks for joining00:49:12
me um i'm not animating anything at the00:49:14
moment00:49:15
what i'm doing is just building a00:49:18
quick kind of simple00:49:21
house model or shed00:49:24
barn type model to be destroyed00:49:28
by uh a tornado00:49:31
so there's our there's our roof material00:49:35
so here's our tornado up here for anyone00:49:38
that kind of joined00:49:39
uh later so this is our tornado model00:49:44
that we've created or simulation i00:49:46
should say it's a bit of a tube but00:49:48
uh you know it'll it'll do for now00:49:51
so we're going to kind of put this00:49:54
building in the path of the tornado and00:49:56
destroy it00:49:58
so i'm just building it in a way00:50:01
that is going to look best when we take00:50:04
it into00:50:05
like a rigid body simulation and we're00:50:06
almost00:50:08
ready to test it so what i'm going to do00:50:12
it looks like i've got some some stuff00:50:14
going00:50:15
through here you can see here i've got00:50:18
maybe the angle00:50:19
changed or maybe just the position needs00:50:21
to come up00:50:22
slightly there we go00:50:27
just need to make sure there's no kind00:50:29
of intersections and then this one again00:50:31
i can mirror00:50:33
so take all of those and mirror those to00:50:35
the other side00:50:37
and then merge those back together00:50:43
that's right it's all about scale with00:50:45
this stuff00:50:46
um you know the tornado is a really00:50:49
massive thing and this building is just00:50:51
going to be completely you know kind of obliterated00:50:54
uh we don't have any00:50:56
wall here yet but let's let's have a00:50:58
look now so what i'm going to do is put00:51:00
an assemble down00:51:01
and an assemble will detect00:51:04
whether each one of these pieces i'm00:51:05
just going to save actually it's00:51:07
probably a good time to save00:51:09
tornado elephant bonanza version 5.00:51:13
so what the oh look there's a few more00:51:16
intersections i need to fix00:51:18
what the assembler is going to do is00:51:19
look at connected geometry so all these00:51:21
pieces that i've created are00:51:22
not connected to each other so the box00:51:25
is connected to itself but then00:51:27
each box is separate from each other so00:51:30
that then gives me the ability for when i go00:51:32
into rbds00:51:34
create pact and then i end up with 41800:51:37
different pieces it's called frac packed00:51:39
fragments00:51:40
so i've got 418 different pieces so00:51:43
let's just fix this00:51:44
quickly this little intersection that's00:51:46
happening here00:51:51
i'm just gonna transform that up a00:51:53
little bit00:51:54
and this one too00:51:58
there we go now i can show you you know00:52:01
what i planned for this as well just00:52:02
before we do that00:52:04
what i'm planning is with this grid here00:52:06
i can just00:52:07
take so if i just click00:52:12
on these select actually i'm going to do00:52:14
it on every00:52:16
second one i could group let's try group00:52:19
uh group by range actually that's not gonna00:52:23
work uh so yeah what a what i'm thinking is00:52:26
if i grab00:52:27
each sort of ring here00:52:31
uh what am i doing ctrl shift a00:52:34
like this or each loop every second one00:52:39
i guess maybe that one as well and i00:52:42
move these so if i00:52:44
hit the transform puts an edit down and00:52:45
then i can move these up00:52:48
and i get my kind of ripple00:52:52
shape and then that will just pass00:52:54
through into the copy00:52:56
and there you go you can see i've got my00:52:57
corrugation it's a little bit simple00:53:00
but the cool thing is these grids all00:53:02
have the same00:53:04
kind of orientation and dimensions so i00:53:06
can just copy this edit onto these even00:53:08
though i've changed the scale of some of00:53:10
these00:53:11
that all just populates and looks00:53:14
good there's kind of weird overlaps00:53:16
going on here00:53:17
but that's all right it's fine so00:53:20
here's my assemble 418 pieces let's put00:53:24
it into a rigid body00:53:27
what is it called rbd bullet solver the00:53:29
slot based one00:53:31
and this i find this is really good for00:53:33
testing sometimes it's not great for00:53:34
doing complex stuff but00:53:36
we can just very quickly turn on00:53:40
ground plane and because i've00:53:43
turned this i've put my assemble down00:53:45
giving them all a name in fact i don't00:53:46
even think00:53:47
i need to do that um thanks harik00:53:51
uh i don't even think i need to do the00:53:52
assemble to run it through this slot00:53:54
based on it actually00:53:55
if you um explore in this tool00:53:59
here here here is where the geometry is00:54:02
coming in and it actually has00:54:04
an assemble in there creating name00:54:05
attributes uh00:54:07
set name if needed there's some some00:54:09
code to do that00:54:10
so it actually does it for you if you00:54:12
don't have one but i think it's a good00:54:13
idea to do it00:54:15
so let's just hit play and see what00:54:16
happens00:54:19
nothing view flag00:54:22
boom there we go look at that00:54:26
it's a beautiful thing and my00:54:28
construction actually um00:54:29
isn't too bad because it it does kind of00:54:32
stay upright for a little bit00:54:33
although all these pieces kind of00:54:35
collapse00:54:37
but yeah i vote to give a 19th century00:54:40
vibe to it00:54:41
maybe i'll put some uh some unnecessary00:54:43
decorative elements in00:54:45
um at the last moment but there you go00:54:49
you know you can see00:54:50
that it kind of how it's going to work00:54:53
how it's going to behave00:54:54
it's obviously just going to fall down00:54:56
at the moment00:54:58
but if i turn off gravity00:55:02
and hit play oh it still explodes00:55:06
and you know what that tells me it tells00:55:07
me that there's intersections00:55:10
when when it's exploding like that so00:55:13
i'm gonna build this actually so that i00:55:15
can do a little bit more complex stuff00:55:18
i'm gonna build this in a net and this00:55:20
will give me a little bit more control00:55:22
so i'm going to go bullet solver00:55:24
um yeah it's it's pretty cool uh just00:55:27
building a model and then running it00:55:28
into the board so00:55:30
quite often i'll just do that as i'm00:55:33
building just to test and see00:55:34
what's going on so here i'm i'm setting00:55:38
up my own rbd solver now so i'm going to bring in00:55:40
an rbd packed object00:55:44
and i'm just going to point that to00:55:45
first context that brings in my building00:55:48
and then i'm going to put down a ground00:55:50
plane00:55:53
because we want it to collide with the00:55:54
ground and if i just hit play on that00:55:58
yeah we can see it's doing the same00:56:00
thing so it's exploding that does00:56:02
tell me that there's intersections or00:56:04
let's check out00:56:05
guide geometry oh look there's some00:56:07
weird stuff going on here00:56:09
with our guide i don't know why these00:56:12
ones happen to be really inflated00:56:16
um might be something to do with the00:56:18
mirror maybe00:56:19
let's turn this on create convex hole00:56:21
per set of connected primitives00:56:23
yeah i don't know that's odd all the00:56:25
other ones are fine if we turn off the00:56:27
display geometry you can see all the00:56:28
other ones are fine00:56:30
but these ones here for some reason00:56:33
and these ones at the top and obviously00:56:36
on the other side because we've mirrored00:56:37
our geometry00:56:39
those are weird00:56:42
so what is going on there00:56:48
where is it here here's our copy00:56:51
geometry00:56:52
and perhaps there's an intersection00:56:56
yeah weird how did i change the inputs00:57:00
for the merge so quickly00:57:01
uh like do you mean like this on my00:57:04
ground plane00:57:08
shift r you can also do it up here00:57:12
you can click these and it shifts it00:57:13
around blackmagic that's right00:57:15
um shift up it's gold00:57:19
uh it becomes slightly more slightly00:57:22
more difficult when you have multiple00:57:23
inputs so00:57:24
you can see it kind of changes the order00:57:26
of the inputs00:57:28
which isn't always a problem but00:57:29
sometimes it can be hard to get the00:57:31
exact input in the right00:57:32
order if you want that but you can see00:57:35
here like if i really wanted to put my mirror00:57:38
in the center input of this merge00:57:40
for whatever reason i could do this00:57:43
where i actually00:57:44
you know i can shift the order here to00:57:47
be a bit more precise00:57:48
and then i can put my mirror right in00:57:50
the center or yeah i can move my copy00:57:52
there and00:57:54
you know flip them around there you go00:57:55
so they're all ordered otherwise doing00:57:57
shift r kind of you know can be a little00:57:58
bit00:57:59
challenging so there you go00:58:03
good tip that's a lifesaver that one um00:58:06
so yeah i don't know what's going on00:58:08
here let's let's go back and have a look00:58:14
why i wonder if there's a slight00:58:17
intersection that's causing it let's00:58:20
just00:58:22
create a little offset00:58:25
plus 0.0100:58:29
0 0 1. we're working a very small scale00:58:32
here let's have a look at that00:58:34
see if it makes any difference reset00:58:38
no that's really weird00:58:42
i'm going to change the collision00:58:43
padding and take it down00:58:45
so because we're working at really small00:58:49
scale sometimes the collision padding00:58:51
does need to be adjusted and we probably00:58:53
will scale this model up actually to do00:58:55
the rbd sim00:58:57
because rbds don't tend to work too well00:59:00
at small scales maybe that's the issue00:59:02
anyway so let's hit play now with the00:59:06
collision padding00:59:07
adjusted and see if it still explodes00:59:11
and there we go doesn't fall down and it00:59:14
doesn't00:59:15
doesn't separate so that's great that's00:59:17
all it was collision padding00:59:19
for whatever reason all the others are00:59:20
fine but those ones00:59:22
are not i don't know why um00:59:25
so yeah that reminds me before i do00:59:28
anything00:59:29
i'm going to scale this up00:59:33
transform now it's it's going to make00:59:36
things slightly more difficult00:59:37
interpolating00:59:38
um some of the values actually00:59:42
yeah let me leave it off for now but00:59:43
i'll see if i can get this working like00:59:45
this00:59:46
because i just realized i've got my00:59:47
tornado as well00:59:49
i would have to scale that up that might00:59:51
cause some problems00:59:52
so i'll leave it at this scale and we'll00:59:54
see if it works00:59:55
and if it does a problem we can scale it00:59:57
up but as a rule00:59:59
bullet does tend to work better at ten01:00:01
time scale or01:00:03
larger scales so yeah i01:00:06
i find scaling up is always a good way01:00:08
to solve a lot of problems01:00:09
so what we're going to do with our01:00:11
simulation here01:00:12
is take our tornado velocities you can01:00:15
see if i middle click01:00:16
we've got our pyro sim here it's got all01:00:18
these velocities in it01:00:20
coming out of the simulation so you can01:00:22
see vel x01:00:24
y and z we've got this velocity field01:00:27
i've got this null here that's out01:00:28
tornado vowels but i'm going to put a01:00:30
blast down01:00:31
and actually blast everything but the01:00:33
velocity field so at01:00:35
name name equals vel.star01:00:39
and delete non-selected and then i'll be01:00:41
left with just val01:00:42
dot x y and z and then01:00:46
then come down here i'll plug this in i01:00:50
can reference the null if01:00:52
if not but sometimes easier to just01:00:54
reference the inputs01:00:56
so i'm going to come in here and because01:01:00
the way that bullet works each piece is01:01:03
kind of a01:01:04
single point with geometry instance onto01:01:06
it you can see when i turn on point01:01:07
display01:01:08
i don't get points where the geometry01:01:11
has points01:01:12
i get a point in the centroid of each01:01:14
piece01:01:15
so because bullet thinks that every01:01:18
object is a point01:01:19
i just realized i'm finally frozen my01:01:21
camera's finally given up so i'll switch01:01:24
switch to camera two because01:01:27
bullet treats every piece as a single01:01:29
point01:01:31
uh i can use pop tools so you know you01:01:34
can use pop force01:01:36
do whatever you like so i can add a pop01:01:37
force in there and01:01:39
add noise to these if i want and it will01:01:41
it will kind of solve oh let me just01:01:43
make sure that i've got this set to01:01:46
active01:01:48
oh let's crank this up i wonder why01:01:50
that's not working01:01:53
my view flag's in the right spot hit01:01:55
play01:01:57
uh01:02:01
look at that budget multiple cameras01:02:02
that's right camera one camera two01:02:05
camera one is uh infinitely better than01:02:07
camera two in terms of quality but01:02:09
uh in terms of performance it's a it's a01:02:12
shocker01:02:13
uh oh pop force i can't wire it in like01:02:15
that i'm01:02:16
so silly so what i'm gonna do here is01:02:18
put down01:02:20
instead of the bullet solver you have01:02:22
this rigid body solver it's super01:02:23
confusing because there's also01:02:26
the rbd solver which is different and01:02:28
you don't want to use that one01:02:30
but the rigid body solver has the01:02:33
ability to change between01:02:34
rbd and bullet bullet is always the one01:02:37
that we want to use01:02:38
but it has these extra inputs01:02:41
um for pre-solve and01:02:44
post solve so that is where the pop01:02:47
force would go and now we'll see01:02:50
that i cranked my amplitude up to see if01:02:52
it was working01:02:53
and you can see you can add pop forces01:02:56
in there so we can do all sorts of crazy01:02:58
stuff with pop forces let's put our view flag here01:03:00
we'll get our ground plane interaction01:03:02
going01:03:03
so we could we could use that but01:03:06
what we're going to do is pop a vect by01:03:10
volumes so we've got our volume our velocity01:03:13
field01:03:14
and here we can choose second contact so01:03:16
that's great but if i couldn't do that i01:03:17
would do01:03:18
stop and i would path to out tornado01:03:21
valves01:03:22
sometimes that's better to do that01:03:23
because it comes when someone's looking01:03:25
at this it becomes very clear what what is being01:03:29
brought in so01:03:30
i'll leave it like that and let's just01:03:32
hit play and see what happens it'll be01:03:34
a bit slower now because we're01:03:36
processing this01:03:38
velocity this huge velocity grid we're01:03:40
bringing that into our simulation every01:03:42
frame so it will be a bit slower and hit save01:03:44
just in case01:03:46
never know oh it's not too bad and01:03:49
oh look at that off our building goes01:03:52
and up into the sky01:03:56
and look it's starting to swirl01:04:00
now it's a beautiful thing so01:04:03
you know it's as easy as that to get01:04:05
rbds to follow pyro01:04:08
don't need to do anything basically just01:04:10
plug that in and01:04:11
off you go and and in fact i could have01:04:13
done this01:04:14
in this in the simplified01:04:18
slot based net as well01:04:21
but i just want a bit more extra control01:04:23
because i am actually going to do01:04:25
some constraints now i don't want this01:04:27
thing just kind of01:04:30
yeah that's right it's ascending to wood01:04:33
heaven um01:04:34
i don't want this thing to just01:04:35
disintegrate immediately like this i01:04:37
want there to be some resistance01:04:39
and perhaps some of the frame to be left01:04:42
behind01:04:44
you know and i don't want this kind of01:04:46
happening where i've got things just01:04:48
sort of floating in space so01:04:51
i'm going to go now and set up some01:04:53
constraints to hold this together a bit01:04:54
more01:04:56
but you can see it's it's got that01:04:57
feeling these pieces all flying off01:05:00
the weatherboards and it all looks cool01:05:02
because we made it in lots of different01:05:03
pieces01:05:04
so so that one in space01:05:08
yeah that's right it looks like it's in01:05:10
space um01:05:12
so let's have a look let's01:05:15
let's have a look at this together so we01:05:16
can get an idea of kind of01:05:19
how we're how we're looking with our01:05:21
tornado01:05:22
in terms of scale and performance so01:05:24
come up here01:05:26
here is my tornado01:05:34
and it's happening very quickly as well01:05:38
so i might want to delay01:05:39
that for a little bit because that01:05:41
tornado is barely formed01:05:43
at this point i might even just start01:05:44
the simulation much later01:05:46
um but you can see it's it's all getting01:05:48
kind of01:05:50
you know carried up into01:05:54
there we may even you know we may even01:05:56
be able to just filter out this01:05:57
low-lying stuff as well so that it only01:05:59
really happens when the tube gets close01:06:01
i don't know01:06:02
we'll have a look at that um but let's01:06:05
let's set up some constraints01:06:07
so that this thing does not just blow01:06:10
apart completely01:06:11
so the first thing that we're going to01:06:13
do is we've got our assemble here i'm01:06:15
going to turn off create pack geometry01:06:17
which is01:06:18
we need it but i'm going to create the01:06:20
name first01:06:21
and then from there i could just do this01:06:24
connect adjacent pieces01:06:28
like this and what you'll see is that i01:06:30
get a whole bunch of little lines01:06:33
connecting geometry together01:06:36
so the way that this works is it takes01:06:38
this name attribute that's been01:06:39
generated here01:06:41
and it connects those pieces together01:06:44
just creates a little primitive01:06:45
joining those two together and on those01:06:47
primitives is the name attribute of the01:06:49
pieces that it's connecting01:06:51
so let's take the radius down so it's01:06:54
not looking too01:06:55
far we don't want these to be super long01:06:56
connections01:06:58
i want them to be really tight like uh01:07:00
you know they're gonna01:07:01
kind of take the place of nails01:07:03
essentially01:07:04
so let's let's look at that first01:07:06
there's got a lot of constraints on this01:07:07
side which is weird01:07:09
um but not so many on this side so01:07:11
that's kind of01:07:12
uh it's a little bit odd to look at why01:07:16
that might be01:07:22
what are you doing there to do some01:07:26
pieces01:07:28
i think it's i think it's the connection01:07:30
between the01:07:37
i don't know what's going on there it's01:07:38
kind of weird i'm not sure why it's01:07:40
giving me the top01:07:41
piece here it's very strange01:07:45
uh anyway let's let's see it's probably01:07:47
fine um01:07:48
ideally yeah i'd like to see the same01:07:50
thing on both sides because this is a01:07:52
mirrored building but you know whatever um so01:07:57
the easiest way that i create these is01:07:59
just using an attribute wrangle01:08:01
you just need to set some attributes01:08:02
it's a string attribute a primitive01:08:04
attribute01:08:05
set to string so s01:08:08
at name or sorry s at constraint01:08:12
underscore name equals and this is just01:08:15
going to be i don't know i'll just call01:08:17
this like01:08:18
uh what do i want to call this01:08:21
uh soft because i think this will be a01:08:23
soft constraint01:08:29
and then the next constraint attribute01:08:31
is constraint01:08:33
underscore type and here you can set01:08:36
things like um pause01:08:40
for position constraint rope for rot for01:08:43
rotational constraint01:08:44
or all for both position and rotation01:08:47
so i'll do all first and we'll see how01:08:49
that performs01:08:50
and then i'm going to create a null here01:08:54
and put01:08:57
out constraint network01:09:04
and then i can plug it into the third01:09:05
input as well um01:09:07
heidi says could you talk about your01:09:09
past project experience a little bit01:09:11
yeah sure um so i've01:09:14
i've been a visual effects artist for01:09:16
around 15 years um and01:09:20
worked you know predominantly in film01:09:23
for that time but i've also worked in01:09:25
kind of games01:09:26
uh not not games so much but games cut01:09:29
scenes you know pre all pre-rendered01:09:31
stuff so that's kind of where i started and01:09:34
then01:09:35
my my first um my first01:09:38
film project was in 2011 and that was01:09:42
ghost rider um two01:09:46
i think spirit of spirit of vengeance01:09:48
whatever you want to call it um01:09:50
and then from there i just you know01:09:52
progressively worked in in more and more01:09:53
films so01:09:55
you can you can look me up on imdb if01:09:57
you want to but01:09:58
um yeah you know lots of kind of just01:10:02
hollywood films action films and01:10:05
superhero films um game of thrones01:10:09
you know that sort of stuff i do a lot01:10:10
of fire and volume work01:10:13
um mainly but i've done all sorts of01:10:16
things01:10:17
um in in my career it's a lot of fluids01:10:20
as well01:10:21
rbds are a lot of fun you know i love01:10:23
love doing rbds01:10:25
um but yeah so so you know lots of lots01:10:28
of different film01:10:29
film work um so i'm trying to think of01:10:33
think of the things that i've worked on01:10:35
um01:10:36
wolverine great gatsby you know i don't01:10:39
know01:10:40
you can you can look it up there's01:10:41
there's quite a lot01:10:43
game of thrones was definitely one of01:10:44
the cooler things that i've worked on in01:10:46
recent years01:10:47
that was a very tough project01:10:51
but it01:10:54
you know it really pushed me to develop01:10:57
my01:10:58
fire skills and push the realism that i01:11:01
was able to get out of01:11:03
you know doing fire so01:11:05
[Music]01:11:08
what i'm doing now is just bringing in01:11:10
the constraint network that i created so01:11:11
constraint network01:11:13
swap path i plugged it into the third01:11:15
context so i can use that01:11:17
constraints to create i've created this01:11:19
soft constraint relationship01:11:20
and here this name needs to match the01:11:23
name that i set here so i called it soft01:11:25
with a lowercase s so i'll just change01:11:27
that01:11:28
and then i should see something come in01:11:31
i've got guide on01:11:34
got guide options here radius is set to01:11:36
zero let's put that up01:11:37
and hopefully if i set this up correctly01:11:41
you might see something it looks like i01:11:43
didn't set it up correctly01:11:46
so let's try and figure out what i have01:11:48
done wrong01:11:51
soft soft01:11:54
what did i do what did i do wrong here01:11:57
yes at01:11:59
check my spelling constraint underscore01:12:02
name01:12:03
primitive attribute01:12:06
uh let's check oh that's that's what i01:12:08
did wrong i didn't pack this geometry so01:12:10
what i usually do um thanks thanks01:12:14
feel free to yeah ask questions um about01:12:16
it i01:12:17
struggle to remember you know the things01:12:19
that i've worked on all the time but01:12:20
um if you have any questions about you01:12:23
know specific projects or just01:12:25
just vfx in general feel free to ask01:12:29
so excuse me so this is what01:12:34
this is the process that i do because01:12:36
what is crucial here01:12:37
with rbds and constraints um01:12:42
is that you don't change the name after01:12:44
you've sent off01:12:46
this path to the constraints because it01:12:48
uses that name to01:12:50
join the pieces together via the01:12:51
constraint so what i do is i create one01:12:54
assemble which basically creates the01:12:57
name01:13:00
and then a second assemble which has the01:13:02
create name ticked off and then create01:13:04
pack geometry01:13:06
um coughing his band in a stream didn't01:13:09
you know i i did not know01:13:11
certainly in this in this uh sure i mean01:13:13
surely in this01:13:14
yeah this day and age where you know01:13:17
everyone's everyone's sick coughing you can make01:13:20
some uh01:13:21
make some allowances for me audrey um01:13:24
so uh hoover says what are your thoughts01:13:27
about the geek nature of the vfx01:13:31
uh industry to be honest i i know that i01:13:34
know that it01:13:35
it worries a lot of people and and01:13:36
people like01:13:39
security in their jobs um01:13:43
but for me it's never really been a01:13:45
problem the the kind of01:13:47
gig nature i mean i i worked at you know01:13:50
the one place for01:13:51
for a long time um well look at that01:13:55
crazy so i just forgot to uh01:13:58
i forgot to give this a rest length01:14:00
which is really important for soft01:14:02
constraints01:14:06
and you can see the pieces are sticking01:14:07
together now01:14:09
so uh yeah i it never really bothered me01:14:14
that you know that that kind of gig01:14:18
economy uh it maybe is a little bit01:14:20
different in australia because we have01:14:22
much fewer um studios01:14:26
that i guess i guess there was01:14:30
a little bit less you know of that kind01:14:33
of moving around01:14:34
and you know ditching people when when01:14:36
there was no01:14:38
no work yeah audrey i mean that i that01:14:41
was my experience01:14:42
as well and i think maybe that has kind01:14:43
of um tainted my view01:14:46
of of permanent work one of my first01:14:49
jobs in the industry01:14:51
uh well my first job actually01:14:54
was doing games cut scenes and01:14:58
you know i was made an employee i was01:15:01
given a permanent position01:15:03
and then the next week they lost a01:15:06
project01:15:07
and they told me i didn't have a job and01:15:11
they didn't tell me01:15:12
to my face by myself in an office they01:15:14
told me in front of everybody01:15:16
they said you know they called a meeting01:15:18
a staff meeting01:15:19
and they were like unfortunately we're01:15:23
gonna have to let daniel go01:15:24
and i was just like wow01:15:27
i was in shock and and gutted you know01:15:30
because it was my first kind of01:15:32
first kind of job and it just really01:15:36
kind of you know um01:15:39
took my confidence away or you know just01:15:42
yeah01:15:43
and ever since then i think i've never01:15:45
really wanted01:15:46
a full-time position because i01:15:47
associated that with like getting fired01:15:50
um so01:15:54
yeah it was it was a really awful way of01:15:57
doing it like it would have been much01:15:59
better if they had01:16:00
told me uh before that meeting instead01:16:03
of in front of everybody01:16:04
um but yeah so01:16:07
i've never really you know wanted01:16:10
that um although now you know i'm older01:16:14
and i kind of feel like01:16:15
job security is a good thing um01:16:19
but yeah it's um01:16:22
i don't know i i kind of like the01:16:26
ability to choose01:16:27
when i'm on a film project as well i01:16:29
like01:16:31
i like the ability to go what are you01:16:33
working on next01:16:35
i'm not interested in that project and01:16:37
and i realized that01:16:39
you know that is a luxurious position to01:16:41
be in where i can01:16:42
say no to something01:16:44
[Music]01:16:46
and that's where you can get to when you01:16:47
have experience and and you have01:16:50
uh options i guess01:16:53
but if i don't want to work on something01:16:55
or i'm kind of sick of working in the01:16:56
same place for too long then01:16:59
that geek kind of economy or those short01:17:02
contracts01:17:03
allows me to go you know what i'm just01:17:05
not gonna renew my contract01:17:08
um but yeah like audrey says and like i01:17:10
was just talking about01:17:13
permanent positions they you know01:17:16
even though they give you the feeling of01:17:17
security they can still let you go at01:17:20
any time01:17:21
um there's slightly more benefits i01:17:22
guess and maybe they have to01:17:24
give you warning but um yeah it's like01:17:28
in the film industry i i feel like those01:17:30
permanent you know positions kind of01:17:32
mean very little anyway um you know look01:17:35
at look at what happened to um you know to01:17:37
rhythm and hughes01:17:39
and and you know all those people that01:17:42
had done amazing work on life of pi01:17:44
and then just like the the studio01:17:48
just shut down basically and they all01:17:49
lost their jobs um01:17:51
i think i think it's you know01:17:54
i don't know i kind of like it because01:17:57
it gives me01:17:58
the freedom to choose and the freedom to01:18:00
leave and and to go elsewhere01:18:02
but um but that's that's just me you01:18:04
know i realize01:18:05
i realize it's not great for people that01:18:07
that are looking for security01:18:08
for their families or um01:18:11
yeah now that i have a family i feel i01:18:14
feel slightly differently01:18:15
security is a good thing but um but01:18:18
still you know it's yeah i think it's all01:18:21
based on that that initial experience01:18:23
that i had01:18:24
um all right so we can see that i01:18:27
hope i hope that helps hoover um01:18:31
you can see that things are sticking01:18:32
together so that's that's kind of01:18:34
working01:18:35
okay these aren't kind of bending which01:18:37
i was hoping01:18:38
they might bend and flop around a little01:18:40
bit um01:18:42
so let's have a look at our bullet01:18:44
settings01:18:46
uh y2 assembly nodes yeah it's a good01:18:48
question um01:18:50
i don't know it's just the way i do01:18:51
things you could use a pack i actually01:18:53
prefer01:18:55
um to have some of the settings on here01:18:59
like the i guess the pack has them as well um01:19:04
yeah i don't know it's just the way i do01:19:05
it i don't really like the pack node um01:19:08
or the unpack node because they they01:19:10
lack some of the settings that01:19:12
like the assemble does um i don't know01:19:15
i i can't remember if there's a there's01:19:17
an actual technical reason why i've gone01:19:20
this way um but you you can do it you can see01:19:23
here like01:19:25
by default the pack only yields one pack01:19:27
geometry so i need to tackle01:19:29
tick on name attribute so you know01:19:32
it's an extra click that i have to kind01:19:34
of go through and maybe maybe that's why01:19:37
um and usually i'll just copy like i'll01:19:39
just duplicate it01:19:40
and that's another reason um but yeah01:19:43
you can definitely do that01:19:45
this is completely up to you um this is01:19:48
just the way i've kind of01:19:50
you know gotten gotten used to doing it01:19:52
the assemble you know it does just have01:19:54
a pack node in it01:19:55
so it's it's just a wrapped up tool01:19:58
um but i just like using it um01:20:02
so and in fact probably what i'll do is01:20:04
actually go up01:20:06
and put the symbol nodes on all of these01:20:07
so i can give them different names01:20:09
and that that will help me identify01:20:11
pieces as well01:20:13
um so what i might do is increase my01:20:16
search radius a little bit01:20:17
let's get a few more connections going01:20:18
on try and hold this together a little01:20:21
more so you can see as i increase this01:20:25
i get more of these dots showing up01:20:29
the primitives get a bit longer but01:20:30
that's kind of okay you can do this01:20:33
primitive scaling so you can put down a primitive01:20:35
node do transformation and set the scale01:20:38
to zero01:20:39
and that will kind of pull those back01:20:41
into a single or01:20:43
pull those back as best it can you can01:20:44
see it doesn't do them all01:20:46
um01:20:49
the work environment in the vfx industry01:20:51
is kind of variable like it it depends01:20:53
really01:20:54
on um on what studio you're at01:20:57
and what kind of environment you're in01:21:00
um01:21:01
as a rule you know it's it's pretty01:21:04
kind of fast paced and um01:21:08
and hard work and long hours sometimes01:21:11
especially around01:21:12
deliveries but yeah it looks01:21:16
you know every studio is different some01:21:18
studios are better than others01:21:19
to work at um and you know some studios01:21:23
have stricter policies around overtime and01:21:27
all that sort of stuff so it really does01:21:31
just depend and that that might also you01:21:34
know be01:21:35
a reason why somebody would stay01:21:36
somewhere longer or not just based on01:21:38
those kind of conditions that they find01:21:40
they're all kind of different but01:21:41
they're all they're all also kind of01:21:44
you know a lot of similarities between01:21:46
them they they all work01:21:47
you know to deadlines and um01:21:50
so i i find any job where you have a01:21:53
time-based deadline no matter what it is01:21:57
it's going to get stressful around that01:21:59
time um01:22:02
you know everybody's kind of a bit01:22:05
a bit on edge or you know just wanting01:22:07
to get this thing done and there's a lot01:22:08
of money at01:22:09
on on the line so it kind of yeah01:22:12
i i find you know whatever job it is if01:22:15
there's some sort of01:22:16
pressure to get something out maybe01:22:18
working in a kitchen01:22:20
you know it it's going to be stressful01:22:22
during that time when you're trying to01:22:23
push something01:22:24
out uh having worked in the game01:22:26
industry for ten years big difference01:22:28
i've seen between the two is vfx tend to01:22:29
be six month contracts01:22:31
yeah well that i that is just the the01:22:33
project duration you know game01:22:35
projects do go for much longer01:22:40
for me personally i prefer the shorter01:22:41
projects because i get a bit01:22:43
bored of working on the same thing01:22:46
i've worked on you know some film01:22:48
projects that last for a whole year01:22:50
and i get really sick of it by the end01:22:52
because you're just looking at the same01:22:53
stuff over and over again it might be01:22:55
different in games but01:22:57
um yeah in film01:23:00
i find you know six months even three01:23:03
months is great six months is kind of01:23:04
like yeah01:23:06
you know that's enough i've seen enough01:23:09
of this thing01:23:10
and i frequently don't want to see the01:23:11
movie when it comes out after that01:23:12
because01:23:13
you've just been looking at this thing01:23:15
for for so long that you're kind of sick01:23:17
of it01:23:18
sick of sick of looking at the actors01:23:20
faces and sick of looking at the work01:23:22
that you've you know kind of been working on because01:23:24
you go through so many iterations and01:23:26
you're just like oh man01:23:28
the joy's kind of you know gone not01:23:31
always01:23:32
but but some projects can be quite01:23:33
difficult so01:23:35
um but yeah that that's the thing with01:23:37
games like01:23:38
they're much longer durations and01:23:40
hopefully the pressure is less i guess01:23:43
i'm sure there are still crunch times01:23:46
when things get a bit01:23:47
a bit hairy but um yeah vfx is usually01:23:50
pretty01:23:51
pretty quick so that's that's01:23:54
why you have those contracts um01:23:58
but i find you know the more experience01:24:00
you have and the better you get01:24:03
the kind of you know you're a bit more01:24:04
in demand so you don't need to worry as01:24:06
much01:24:07
about um about not being hired again01:24:11
as long as they've got work and they01:24:14
like you and you can do good work in a01:24:16
timely manner01:24:17
um then you know you get hired back and01:24:20
you don't need to worry that01:24:22
that you're gonna lose your job um01:24:29
uh burnout i look i don't really01:24:33
suffer from burnout that much i mean i01:24:35
work very hard01:24:36
um and it's01:24:39
you know sometimes sometimes quite01:24:41
stressful um01:24:42
and and i have been burnt out before01:24:44
it's i wouldn't say it's a massive issue01:24:46
um only only when you know01:24:49
the situation gets very extreme um but01:24:52
yeah it happens01:24:53
you know it does happen to people um i01:24:56
find a lot of new people come into the01:24:58
industry and01:24:59
um you know don't realize how much work01:25:02
it is01:25:04
and you know then they can reconsider01:25:06
their options but01:25:08
yeah look it's not that bad i mean i01:25:10
think01:25:11
it again it depends on the studio some01:25:13
studios can be01:25:14
can be quite bad for it um and01:25:18
that's you know people leave then and01:25:20
then they have to change and they have01:25:21
to get better01:25:22
and word spreads pretty quickly around01:25:24
the industry01:25:26
and a studio will get a bad reputation01:25:27
if they treat their artists01:25:29
poorly so yeah even though that stuff01:25:32
does happen01:25:34
it kind of you do see it change because01:25:38
because it kind of um yeah otherwise i01:25:41
won't be able to hire people01:25:42
no one will want to go there certainly01:25:44
seniors you know if they01:25:45
hear that some place is bad to work or01:25:47
there's long hours then01:25:48
they'll just be like no that's not for01:25:50
me you know01:25:51
i want to spend more time with my family01:25:54
so they will have to change their01:25:56
culture and and you know01:25:58
try and work out how to how to make01:26:01
things make things better for their artists um01:26:04
so yeah look i'm not gonna you know01:26:07
sugarcoat it and say that burnout01:26:08
doesn't happen i wouldn't say it's a01:26:09
massive issue for me01:26:11
um but you certainly do work some long01:26:13
hours around crunch time01:26:15
and that is just that's just part of it01:26:18
some people don't you know some people01:26:19
will just leave they'll just go home um01:26:22
and that's okay yeah that's their choice01:26:26
to do i you know i really enjoy01:26:29
the work and sometimes i get really01:26:32
invested in a shot that i'm doing so01:26:34
i'm kind of happy to put in a bit of01:26:36
extra01:26:38
time because i want to see it you know01:26:39
get realized and01:26:41
and see it kind of come to fruition and01:26:43
be as good as it can be01:26:46
and that's just a personal choice you01:26:48
know so01:26:50
what am i doing here i'm just trying to01:26:51
get this constraint behavior a little01:26:52
better01:26:53
so i'm going to take down my stiffness01:26:56
let's see if we can get these to kind of01:26:57
i want these panels to kind of fold a01:26:59
bit more not really01:27:01
maybe it's to do with the um01:27:05
longest week you've had to work hours01:27:07
wise01:27:11
that's a good it's a good question01:27:13
michael um01:27:14
let's let's bring up the calculator01:27:17
let's see if01:27:18
i worked from 9 00 a.m01:27:22
till midnight every week01:27:26
or every day of the week that would be01:27:28
what 12 hours01:27:31
13 14 1501:27:34
hours i guess 15 times five01:27:38
75 hours i'm sure i've probably done01:27:40
more than that sometimes but01:27:42
you know 80 hours could be could be01:27:44
something but look this is not01:27:46
all the time um and it certainly01:27:49
wouldn't be i wouldn't be a junior doing that work01:27:51
it's usually when you get into01:27:53
kind of supervision and leading and01:27:55
stuff like that when01:27:57
when you often have to put in a bit more01:28:00
bit of extra time or you know people are01:28:02
relying on you or you need to fix01:28:04
problems then that's when you can really01:28:07
start01:28:08
putting in the hours01:28:11
but yeah you know it's not all the time01:28:13
it's just01:28:15
just sometimes and hopefully you know01:28:18
you work at a place where they're gonna01:28:20
pay you for it as well so01:28:21
um so that always helps um01:28:26
get a nice little uh nice little holiday01:28:29
fund going and uh you know01:28:31
think about your holiday at the end of01:28:32
it have some time off01:28:35
so yeah i don't know if this is this is01:28:38
working too well what i'm gonna do here01:28:39
is01:28:40
i'm gonna make some glue networks as01:28:42
well so i'm going to take this01:28:43
constraint network here01:28:44
this can connect adjacent pieces and01:28:48
adjacent pieces from surface points got01:28:51
our search radius so we can01:28:52
we can really crank that up if we want01:28:54
but this would be to create01:28:56
a glue network and the glue will serve01:28:59
we don't need the primitive but i'm01:29:01
going to take this01:29:03
this wrangle here and i'm going to01:29:05
change this01:29:06
hey john how's it going um i'm going to01:29:09
change this constraint name to glue01:29:11
and this one will be our01:29:14
glue network01:29:19
there we go so what this will do is01:29:22
serve to hold everything together so i'm01:29:24
going to copy that01:29:27
data options i'll change to sop and put01:29:29
in the stop path01:29:30
out blue network01:29:34
and glue constraint relationship01:29:37
and i think you know honestly with the01:29:39
industry um01:29:41
the way that it's going with being able01:29:43
to work from home01:29:44
as well is is a really good thing and i01:29:47
think that will improve01:29:50
you know people's lifestyles and and01:29:53
hopefully be a bit more flexible i think01:29:55
yeah that's one of the hardest things is01:29:57
um certainly when you're working till01:29:59
midnight uh01:30:01
and then you have to go home and if you01:30:02
live really far away from the studio01:30:04
then it's kind of like it really drags on you but01:30:07
um01:30:08
if you could work from home if you could01:30:10
go home have some dinner01:30:12
say hi to your family and then you know01:30:15
log back into work for a couple of hours01:30:16
to fix that thing or you know you just01:30:18
want to finish something off01:30:20
um that's really bugging you then01:30:23
you could do that from home and that you01:30:25
know that would be01:30:26
that would be great it would really kind01:30:28
of i think make01:30:30
the lifestyle a bit more flexible um01:30:34
so that glue is really strong let's turn01:30:37
that down and see if it breaks when that velocity01:30:41
hits it it doesn't look like it01:30:44
so the velocity might not be generating01:30:48
the velocity field from that pop force01:30:51
these pop volumes01:30:53
because it's set to update force it01:30:55
might not actually be registering01:30:57
a value on the glue if you01:31:01
want to see what glue is registering you01:31:03
can go to the geometry spreadsheet01:31:05
relationships01:31:06
constraint network 2 is the one we're01:31:08
looking at open it up01:31:10
jump into the constraint network and01:31:12
then on geometry01:31:14
under primitives here is the attributes01:31:17
that are being registered on the glue01:31:18
network and you can see01:31:20
if we sort this by impact01:31:24
they are registering an impact actually01:31:28
but it must be really low01:31:32
we can see it's like01:31:35
let's have a look around here oh01:31:41
right at the start here can see it01:31:43
starts at zero and you can see it's like01:31:45
e negative something which tells me that01:31:47
it's like01:31:48
zero point zero zero zero zero zero zero01:31:50
zero01:31:52
uh you had a crash john that's not fun01:31:55
and no saving01:31:58
that sucks that really sucks i01:32:02
i really hate losing so much work01:32:07
and just you have to recreate it and01:32:09
there's nothing you can do01:32:10
and it just really hurts i feel bad for01:32:13
you man01:32:14
um so these are really really low values01:32:17
so it means that we really need to take01:32:19
our strength down01:32:20
um and i guess that's just that's just01:32:23
what's happening with these proper01:32:24
volumes it's not imparting a really01:32:26
strong impact01:32:27
on these collisions but by seeing that01:32:30
then we can go okay cool so we know why it's not01:32:32
working our impact values are really low01:32:34
let's turn our strength right down01:32:37
go 0.1 that'll probably still be too01:32:39
high but let's see01:32:40
if we get any braking happening no01:32:44
let's go just put it put it super low01:32:48
even that is probably too low so one01:32:51
thing that01:32:52
you know we could potentially do is01:32:55
put down a sop solver here01:32:59
yeah i always forget to turn on auto01:33:01
save as well john01:33:02
um try to get into the habit of just01:33:05
hitting control s01:33:06
before i simulate or before i do01:33:09
anything crazy but01:33:10
yeah i always forget to turn it on as01:33:12
well i wish i know01:33:14
you can there is some script that you01:33:16
can run python or something i've seen01:33:18
somebody do where you can enable auto01:33:20
save automatically but um01:33:23
yeah it's uh it's so annoying that it's01:33:25
that it's not on by default01:33:28
so sop solver relationship geometry here01:33:32
here's our constraints and we can01:33:34
actually delete them01:33:35
here based on something so what i might01:33:38
do is use an01:33:42
object merge to bring in01:33:46
my tornado01:33:49
so here's my tornado valves but i'm01:33:52
actually going to bring in01:33:53
the volume itself so out tornado01:33:56
volume go back to my sop solver here we01:34:00
go01:34:01
and dot slash dot slash dot01:34:04
slash out tornado volume there it is01:34:08
so here's our constraints here's our01:34:10
volume if we scrub forward01:34:12
we can see that volume coming in here01:34:16
and i'm just going to do this i'll put a01:34:18
points from volume down on that01:34:21
ah no worries john um01:34:25
put a points from volume on our tornado01:34:27
here01:34:28
this is just going to copy some points01:34:30
onto it01:34:32
and then i'm going to attribute transfer01:34:36
from actually from there to01:34:39
oops other way around01:34:43
like that01:34:46
there we go so from here i'm going to01:34:48
put color down01:34:52
it's going to be red i'm just going to01:34:55
turn my simulation off so i can scrub01:34:56
this01:34:58
there we go you can see it go red let's01:35:01
set this one to be black01:35:05
hey thanks john you have to uh you have01:35:08
to watch01:35:09
watch back from the start but yeah just01:35:11
making a little procedural building01:35:13
so you can see i can control the amount01:35:16
that this is transferring and this at01:35:17
this point01:35:18
is quite far away so i'm going to only01:35:20
transfer a little bit01:35:21
so that when it gets like really close01:35:25
that's when it's going to transfer01:35:26
to it so like01:35:29
even that01:35:34
and this means that it's going to kind01:35:36
of hold together the building01:35:38
until this thing gets close01:35:41
really close or even on top of it you01:35:43
know right at the end here01:35:45
but it kind of really smashes it like01:35:47
that01:35:48
so what i'm going to do then is just put01:35:51
a blast down01:35:53
and just say at cd.x greater than zero01:35:58
and what that's going to do is we look01:36:02
at these red ones so we set this to points01:36:04
because cd is a point01:36:06
attribute there we go you can see that01:36:09
it removes those ones that are red but01:36:11
when you can see they come back and they01:36:13
reappear but when we run this as the01:36:15
solver they won't come back hopefully01:36:17
pretty sure um let's see what happens01:36:21
you play every time you bring in01:36:24
something from sops especially something01:36:26
like the volume01:36:27
it is going to have an impact and a slow01:36:30
down when that's processing so these are01:36:33
things that you need to consider but01:36:35
you know hopefully hopefully it's going01:36:37
to work and i think what we should01:36:38
actually do is instead of running this01:36:40
from the start01:36:42
i'm going to run this from like01:36:45
you know maybe frame 200 or something so01:36:47
that we're not01:36:48
kind of we're not dealing with this01:36:52
let me just hook this up here01:36:55
we're not dealing with this until this01:36:57
thing gets much closer01:37:00
so maybe like01:37:04
i don't know01:37:08
maybe even around here two01:37:15
oh what do we do01:37:18
we'll go here like 180 150 maybe let's01:37:21
try 150.01:37:24
so we'll set our start frame to 15001:37:31
and let's have a look at that here01:37:38
so we should see now these constraints01:37:40
get broken01:37:46
hopefully01:37:48
oh there we go it's very kind of uh01:37:51
abrupt so what what i might do with that01:37:55
is with this guy01:37:58
i'm filling the whole thing with points01:38:00
even these really fine bits here01:38:03
but what i could do maybe using iso01:38:05
value01:38:06
see if that works doesn't really seem to01:38:09
be01:38:10
nope so what i'm going to do here my01:38:13
object merge i'm going to put a01:38:14
volume samp volume vop down01:38:21
and i'm going to run this density01:38:23
through a fit01:38:28
pipe it out again and01:38:33
set my view flag on that there we go01:38:36
so what i'm doing is i can actually clip01:38:38
out the low density stuff and all this01:38:40
stuff that's kind of flying around the01:38:42
house here you can see it's lower density than01:38:44
this stuff we've got up here this stuff01:38:46
is very high density and this is low so01:38:49
by upping this source min i can actually01:38:51
clip01:38:52
out all that really low stuff source max01:38:55
so that01:38:56
i'm i'm almost at one here and i can see01:39:00
i'm kind of01:39:01
i've still got a lot more stuff in there01:39:02
and it's no longer clipping01:39:04
so i'll put this source max up let's go01:39:06
to 1001:39:08
and then you can see you know i can01:39:10
raise this i can clip01:39:12
a lot out so i can try and remove01:39:15
most of that really thin stuff so let's01:39:17
go like nine and ten01:39:20
nine to twenty so you can see i can01:39:23
actually really01:39:24
clip out a lot of that stuff and then01:39:27
when i do my points from volume01:39:29
i'm gonna get that instead of that01:39:32
so that might help01:39:36
maybe it's a little bit aggressive let's01:39:38
go01:39:39
maybe seven two01:39:42
fifteen so you gotta kind of play with01:39:46
it01:39:47
don't wanna clip out too much we could01:39:49
also actually use01:39:50
our original line to drive this01:39:54
so here's our line01:39:57
actually probably need the converted01:40:01
line here let's do that null01:40:06
out nurbs01:40:10
mine okay01:40:14
so we could actually use that instead01:40:16
that would be faster01:40:18
to do because we're not taking a volume01:40:21
so let's do our nurbs line01:40:24
and then we can just make sure because01:40:25
the line kind of01:40:27
determines where the center of that01:40:31
vortex is or the tornado we could just01:40:33
do it based on that01:40:34
so that it's not going to uh01:40:38
go red until the center of the tornado01:40:40
is really nearby01:40:41
let's have a look see if it goes red at01:40:44
some point01:40:45
probably towards the end or we because01:40:47
our line is so01:40:48
far away we might need to just increase01:40:50
our radius01:40:51
here there we go so you can see it there01:40:56
look at that there you go01:40:59
and actually because it's not deleting01:41:01
if i don't put that all the way up so it01:41:03
deletes everything01:41:05
it's going to leave some of those glues01:41:06
in place which actually might be kind of01:41:08
cool01:41:09
all right so let's let's run this and01:41:12
see how it looks01:41:15
it's going to be faster as well because01:41:17
we're not rasterizing those points on01:41:18
the volume anymore we're just using that01:41:20
base line01:41:21
it's always handy if you can go like01:41:24
right back01:41:25
to the original thing that's driving01:41:27
everything and use that01:41:29
instead of the things that are following01:41:31
it01:41:34
might might just be a better way to go01:41:36
it01:41:37
looks like it doesn't really actually01:41:38
start until much later so we could start01:41:40
our simulation much later01:41:42
as well let's just see01:41:47
see when it kicks in01:41:57
at some point i've only i've only01:41:59
simulated up to like01:42:00
um 400 on this thing anyway i think so01:42:03
we're not gonna01:42:04
end up with much much time to run our01:42:08
sim there we go01:42:12
but he's not flying up anymore all right01:42:15
so let's let's make this happen sooner01:42:23
let's put that up to 10.01:42:34
there we go let's try that start at 150.01:42:42
there we go it's all gone all right01:42:46
it'll be a bit fiddly sometimes01:42:50
let's try eight and so i'm turning this01:42:53
off to try and see01:42:55
when that's happening01:43:00
looks like it's a very fine line let's01:43:02
try nine01:43:10
so what might be happening there is that01:43:12
it's deleting some of those01:43:14
not deleting them all but then i've set01:43:16
this really low so01:43:17
maybe they're just breaking and set it01:43:19
to one01:43:21
there we go uh and the whole house is01:43:25
being pulled off the ground01:43:31
is that what happens in uh01:43:35
um the wizard of oz so house get carried01:43:39
i think it does01:43:40
it's a little bit wizard of oz there we01:43:42
go01:43:46
that's kind of cool it's not really what01:43:47
i um had intended but it's kind of a01:43:50
cool thing seeing that house fly around and01:43:53
we can actually see01:43:54
as it goes up and that01:44:00
that line breaks those constraints01:44:03
because it gets closer to the line as it01:44:05
gets sucked up01:44:06
it's actually disintegrating as it goes01:44:09
through the air which is pretty cool sometimes you can01:44:12
have these01:44:13
you know nice happy accidents now01:44:16
we could turn back on our gravity let's01:44:19
let's see what happens with gravity on01:44:20
does it break all the01:44:21
glue constraints yeah you can see it01:44:23
does so01:44:24
the gravity is imparting a much higher01:44:26
force and causing the impact01:44:28
to register much stronger so01:44:32
let's let's put this back to default01:44:34
which i think is ten thousand01:44:36
and see if the gravity still does that01:44:39
no it doesn't01:44:40
so that's good good sign and you can see01:44:43
with gravity on we get things falling01:44:44
back down as well so we're getting01:44:46
things picked up which is good01:44:48
but we're also getting things you know01:44:50
kind of falling down and maybe the01:44:52
gravity we don't want it to be01:44:54
you know so that we can kind of get that01:44:55
feeling of scale maybe the gravity01:44:57
we drop the value doesn't always have to01:45:00
be01:45:01
negative 9.8 let's just make it negative01:45:03
two01:45:05
because we're also setting force here so01:45:07
they're going to fight against each01:45:08
other01:45:10
but having some sort of downward force01:45:13
will help01:45:17
and certainly because once these things01:45:21
kind of01:45:22
fly outside of the um01:45:25
outside where the tornado is if they get01:45:27
kind of flung off01:45:29
um it01:45:32
you know it will kind of fall back down01:45:34
again so that that would be kind of cool01:45:36
um who01:45:40
sorry for my ignorance john who is ray01:45:42
bulger is he one of the actors01:45:44
in um the wizard of oz i probably should01:45:47
know that01:45:49
um but that that is cool if that's the01:45:51
case01:45:53
so there we go there's like that's a01:45:55
cool kind of moment happening there01:45:57
where we get this01:45:58
like few pieces being pulled off and01:46:00
then this01:46:01
complete kind of collapse oh he's the01:46:04
scarecrow oh cool01:46:07
that's um that's very cool01:46:12
i haven't seen it in ages i've probably01:46:14
watched it again it's been a long time01:46:18
i think i think i remember being quite01:46:21
scared of the witch01:46:22
when i was when i was really little01:46:26
all right so yeah this is cool it's01:46:30
i would hope for a little bit more um01:46:34
kind of break up i guess before that01:46:36
moment01:46:37
that that kind of that moment there um01:46:41
but it is kind of cool i do like the way01:46:44
it's going01:46:45
let's save it and let's have a look at01:46:47
it together with our01:46:49
oh there we go look at that um01:46:53
so let's let's flip book this and and01:46:55
have a look what i'm going to do is set01:46:57
my background to01:46:59
let's say gray dark01:47:02
yeah dark looks good let's turn that off01:47:05
and let's let's flip book this and see01:47:09
what it kind of looks like it's probably01:47:11
gonna01:47:12
probably looks like i'm gonna lose my01:47:14
cache when i do this but oh01:47:15
i hit save i just realized we're almost01:47:18
out of time so oh look at that01:47:20
that's not that's not great what's going01:47:22
on there looks like it's frozen in time01:47:28
uh okay let's try that01:47:33
okay oh it's a little bit hard to watch01:47:36
it's like that um01:47:39
all right i'll just minimize that for01:47:41
now we can watch it in the viewport01:47:44
um so yeah i think i think this is01:47:47
on the right path maybe it might be cool01:47:50
to have some more buildings in there01:47:52
um i mean you know you could really go01:47:54
crazy with uh01:47:55
with something like this um01:47:59
thanks hardik01:48:00
[Music]01:48:03
i don't want um go back to work neither01:48:06
um you know audrey01:48:09
and i were talking about uh filling this01:48:11
with uh with sharks01:48:13
this this barn which which would be01:48:16
pretty funny01:48:17
um even the tractor in there you know01:48:20
would be kind of cool having a tractor01:48:21
in there01:48:22
or some other some other kind of farm01:48:24
stuff around it01:48:25
getting kind of pulled up uh a tree you01:48:28
know would be would be awesome01:48:30
a little bit more complicated but you01:48:32
can see this kind of nice01:48:34
you know the nice thing about having it01:48:36
be a gradual effect is you get that01:48:39
yeah cows totally john um i don't i01:48:41
don't have any cow models i have to try01:48:43
and find one01:48:45
having this nice gradual disintegration01:48:48
you know instead of the whole thing just01:48:49
kind of01:48:51
blowing out and and getting sucked up01:48:53
straight away it just creates these01:48:55
really nice moments01:48:56
um and it's it's really getting buried01:48:59
here01:49:00
so that's not ideal because we might01:49:03
lose01:49:04
some of the really cool things that01:49:06
we're getting01:49:07
um which on a broomstick yeah that's a01:49:09
good idea flying around01:49:11
and cackling um01:49:14
audrey working till midnight something01:49:17
ridiculous flying yeah01:49:19
i didn't i didn't manage to get anything01:49:20
in this time but um01:49:23
i was i was going for realism first and01:49:25
then01:49:26
and then surrealism maybe next week um01:49:30
maybe some pigs as well flying around01:49:32
would be would be fun01:49:34
i can try and make this a whole a whole01:49:36
farm01:49:37
farmyard scene maybe some silos would be01:49:39
cool as well i'll have to watch um i01:49:41
have to watch twister again01:49:44
and see um see kind of you know01:49:47
what sort of things look really cool and01:49:49
and maybe01:49:50
maybe some real stuff as well i01:49:52
shouldn't just watch a movie for01:49:53
reference01:49:55
um super rigid01:50:01
um hey thanks01:50:04
hardik i'm i'm glad i'm glad it's easy01:50:07
for you to uh01:50:08
attend what what time is it though for01:50:10
you in india i think we're on01:50:12
relatively similar time zones01:50:16
um it's morning for me here too01:50:19
even though it's very dark in my room um01:50:22
here we go here's the here's the main01:50:24
event happening now01:50:31
and of course this is just the rigid01:50:33
body simulation so01:50:35
lots of secondary um01:50:39
lots of secondary stuff we could add to01:50:41
this01:50:42
dust coming from the building itself01:50:44
particles01:50:45
um are you saying oh to the it's morning01:50:49
in where i am even though i'm sitting in01:50:51
darkness01:50:52
audrey um 7 25 oh that's not too bad so01:50:55
you're like uh01:50:57
what is that four hours behind maybe01:51:01
um01:51:05
well i'm glad i'm glad you're able to01:51:07
attend and it's not too01:51:08
not too hard it's always hard with01:51:10
different time zones getting you know01:51:11
lining up01:51:12
um yeah this is looking cool01:51:16
liking that let's see what we're up to01:51:19
here01:51:20
still flashing around like crazy01:51:26
i mean i think this simulation you know01:51:29
could01:51:30
be better the the pyro sim is a little01:51:33
bit01:51:34
a little bit insane01:51:37
you know it's not super tornado-y you01:51:40
know there's elements of it but01:51:42
some of this stuff is a little bit crazy01:51:44
um it's cool01:51:46
don't get me wrong but um you know01:51:49
it's possibly not tornado enough it01:51:52
starts to get there right at the end i01:51:54
think that's the issue01:51:55
like it it takes a long time to build up01:51:58
um 10 p.m oh that's not too bad01:52:02
whoever i guess at least it's not like01:52:05
the middle of the night01:52:06

light flickering issue i don't know what's01:52:50
going on there with the lights01:52:52
but um yeah there's some weird stuff01:52:56
going on here like things hovering kind01:52:57
of in midair01:52:58
i think that's probably like this piece01:53:01
really gets kind of stuck01:53:03
um oh01:53:06
cool i hope it's going okay john that um01:53:09
that project's really fun it's quite01:53:11
complicated the the01:53:12
um the uh like t-1000 effect01:53:17
um so yeah this piece i don't like that01:53:20
i don't like what's going on there it's01:53:21
just kind of getting caught in the air01:53:24
and i suspect it's because the gravity01:53:26
is so low01:53:27
um cool that that's yeah that's great01:53:30
thanks super01:53:31
i think um that's all you know that's01:53:33
all i can hope is that01:53:35
you guys pick up some little tips and01:53:36
tricks from me just working away and01:53:39
doing some fun things and if you ever01:53:41

it's starting to look really cool01:54:04

tornado effect so i think01:54:08
if i simulated this for a bit longer01:54:10
maybe if i even just went to 50001:54:14
it would you know it would really kind01:54:16
of be01:54:17
quite cool we've got a lot of cool stuff01:54:19

want to do is break up01:54:22
these big beams that's really kind of01:54:27
breaking the scale for me so we want to01:54:29
get them01:54:31
