c4d people work in advertising doing motion graphics and stuff....
Houdini artists work in every field, TV and Movie VFX the most obvious.
Apples and Oranges, despite there being an obvious overlap, the overlap exists only in one direction.
Otherwise show me the thousands of movies and TV shows with VFX done by C4d artists - you can't because they don't exist - reality proves you a retard.
Same applies to video games - show me the hundreds of games made with C4d...
C4d is for simple stuff and point and click solutions are for low hanging fruit problems, both fail the moment shit gets serious and complex.

trash and unimportant, go kys ainigger

am i missing something or is karma xpu's subsurface really slow and noisy? when compared with the rest of xpu's perf i.e. which is pretty impressive. this is just real noisy, but i'm just getting started with it.

>>918181
what do I need to do to get on xk studio's level?

>>919370
SSS in nature is really noisy depending on Your mesh structure ( it tries to calculate depth of the surface between each spot for light pass through)

The thing You ar emissing is probably increased sample rates for it.

>>919433
nah i'm aware SSS is going to be slower than non-SSS surfaces, it's just that Karma's performance with non-SSS materials is so good (compared with arnold or even redshift) i was a little surprised SSS felt slower than even arnold.
but yeah, just getting started so probably just need to figure out where to optimise.
it's a little strange that the SSS bounce limit is set to 0 by default as well on karma render settings.

Is it possible to import an Unreal scene into Houdini?

19.5 has changed something about RBD emission and I'm not totally sure what's going on:

https://www.tokeru.com/cgwiki/index.php?title=File:Emit_packed_rbd.hip

This set up (and one of my older ones) is completely broken on 19.5 due to this change.
Removing the "lift_on_y" transform makes it behave somewhat normally, but that's not a fix.

15 minutes later:
worked out a fix, but i'm not actually sure what's causing the problem:

1. in the pop source inside the dopnet:
attributes tab > inherit attributes change to > "v name"

the output from the dopnet itself is still fucked

2. dopimport > pic related
3. attrib delete > pt attrib > "pivot"
4. copytopoints enable piece attrib

what do you do with python in houdini?

>>920315
pic-related is my most elaborate project.
it'll quickly spit out arnold materials/hook up imperfection maps for libraries i have. similar thing for hdri's. i need to port these over to redshift and karma now though.

other stuff is also shading centric. linking uv parameters for all selected image nodes. placing triplanar nodes between all selected image nodes.

last thing, when i made that confused post, was importing X number of images in at the same time because i've been doing some stuff where textures are switched based on attrib and need to bring in 50 images at a time.

i do eventually want to look at some of the fancy entagma stuff and data vis as well.

how are we going from this

This was a serious question btw.

https://www.youtube.com/watch?v=_g_0pb5S3Q8

>>922279
>>922446
fluid sim with some viscosity? sure. more than one way to do it.

>>922461
Not that simple. Cum behaves as a mixture of three different liquids, and those liquids visibly decompose and change consistency with time. Can Houdini do simulations with multiple interacting liquids? Can it preserve volume & generally look nice transforming one into another? Can liquid properties vary spatially and temporally? I'm very serious about my cum.

>>922462
>Can Houdini do simulations with multiple interacting liquids?
sure. you can set properties on a per point basis if you really want to.

>Can it preserve volume
the flip solver has reseeding options.

>generally look nice transforming one into another
not sure what you mean, but if it's connected to:

>Can liquid properties vary spatially and temporally
then yes, you can vary properties mid-simulation based on any number of conditions or you can keyframe them if you're a neanderthal.

>>922463
Damn, that's honestly impressive if it actually works well.

>>922462
>Cum behaves as a mixture of three different liquids, and those liquids visibly decompose and change consistency with time.
It's evident that you have given that topic some thought, your seriousness is acknowledged.....(btw. other anon here).
>Can Houdini do simulations with multiple interacting liquids?
of course it can. What type of question is that?
Houdini does simulations with multiple interacting forms of anything no matter the state of aggregation and physical properties.
>Can it preserve volume & generally look nice transforming one into another?
>Can liquid properties vary spatially and temporally?
yes, yes, I lack the knowledge of how to do it, but I know for certain that it'll work.
You'll jizz all over the place once you find out how...

>>922466
The issue is that SPH isn't just particles bouncing around. To make something liquid, you have to express the invariants that make it so IRL. Shit like incompressibility is essential and tricky to get right IMO. It's impressive if Houdini has a general solver that handles really unusual situations like cum well, because the fewer constants you have to work with, the trickier solving the equations gets. And this isn't necessarily a problem of convergence, but accuracy in the solver. Naive SPH implementations tend to look uncanny or lacking compared to eulerian methods.

>>922467
while i think there's an sph solver still buried in houdini somewhere, the current methods for fluids are FLIP and vellum (xpbd)

>>922470
oh there's also another psuedo-fluid thing in pop networks, but i have no idea what they're doing to solve that.

>>922470
XPBD uses SPH and FLIP is a hybrid approach IIRC. SPH just means that you use a kernel over your particles (smoothed particles) and the apply constraints (hydrodynamics) based on the integration of these kernels.

Is Houdini Indie 2 year worth it ?

>>922570
Wrong phrasing. Are you worthy?
Everybody can buy a license, not everybody can use Houdini - does your ability to use it stand in healthy relationship to the investment?

how do you jump from tutorials to actual production work?
I seem to forget everything without hand holding.

>>922986
keep notes.
do more test projects, fewer tutorials.

in solaris, adding a light, importing two simple primitives, suuzanne and a grid from /obj/ then trying to create a material library with a red material and selectively assign it to one (1) object. It doesnt work. If i type in /obj/grid1 in primitives it doesnt assign the red material. The only way it works is if i assign to all primitives with /* .......but, I dont want this.

What do I do?

>>923159
doesnt matter if i use prman or karma, the result is the same btw. Using prman for lama

Also, how do I get my /obj/ transform edits to carry over when i use the sop import node? For example, I moved suzanne up a few units in order to make her sit entirely above the grid, but it doesnt carry over

>>923162
i figured it out. Had to export an alembic instead of obj and use the scene import lop

>>923159
>>923162
>>923181
m8, you can literally just drag and drop the primitive from the scene graph tree to assign box

the path wouldn't have /obj/ in it at all iirc. paths are reconstructed for solaris and the scene graph tree is the path hierarchy

>>923212
fyi, you can turn the hdri in the viewport off by hitting d on the viewport, it's in the background tab. drove me nuts.

>>923212
>m8, you can literally just drag and drop the primitive from the scene graph tree to assign box
the tutorial i was following had me type everything in. You should blame them.

Am I supposed to build anything up in /obj/? I am doing a test project of a simple sci fi vehicle, textured to the 9s with painter and mtlx lama, starting with some still renders and if that goes well some animation. I know, i know, its cpu only, but I have 12900k and what i have seen with lama has truly been next gen.

>>923219
the only thing putting me off this mtlx lama quest is that prman in houdini is really really unstable. This makes me think twice and say that maybe I should just sacrifice some visual fidelity and just swim downstream with karma and karma xpu

>>923219
>Am I supposed to build anything up in /obj/?
t bh i have very limited experience with solaris so i really have no idea what you're "supposed" to be doing. i'm guessing in a production scenario you'd just ingest the usd of the model from a different department.

i haven't used lama at all but am curious about it. in no rush though since i have no idea when others are going to start adopting it / if ever.

>>923228
Hey Anon,
Solaris is used to prep the scene using your usd/obj/fbx we to prep the scene for rendering.

Its basically layout to render part of the process

>>923234
I have a great need for variations within solaris but I cant get them working. I'm following

https://youtu.be/TLJPDt4YpYM?t=769

I can't get my setvariant node to work. People say I need to create a duplicate reference of my material, but that reference doesnt show up in the scene graph. In my pic rel, variant edit_pxrsurface 1 / 2 are Green / cyan. However, setvariant only shows the original red.

How do I properly reference and assign that reference so i can use setvariant?

>>923241
Hey Anon,

Double check, you should set your reference layer prior to variant and make sure you inherit from first input and give it a path

You dont really need duplicate reference I think, just use edit parameters on your og shader and plug it inbetween the begin and end block, like you did.

Cant tell much from the setup but it looks like you have done everything okay.
I just followed the tutorial as well and managed to get same results, retrace your steps.

how do i go from intermediate-level, know how to work with quaternions and matrices, to big-brain level like:
https://houdinigubbins.wordpress.com/

>>923321
work with bigger matrices

>>923316
Still not working...I have it set up like this now and its close to what I see at 12:45 in the renderman video. I switched over to 19.5 and still cant use setvariant. I think I'm getting confused with assigning the original material from the material library because it doesnt show up as an option. I've also heard that you need to deactivate that og material in order to lower its level, but it just removes the material entirely.

I have uploaded my 19.5 hip to the location in the pic rel

>>923321
fuck man, my IQ is not high enough to understand that website, might as well get back to blender

I need to assemble my scenes and I'm kinda tired of Maya lagging. Does Houdini handle geometry better than Maya? And should I use Solaris?

>>923409
Can I ask, why not just use the component builder workflow to make your variants?

https://youtu.be/EgTqz6y_oAs

>>923442
What's making your Maya scenes lag? Using USD/Solaris *can* make your scenes a lot more responsive, depending on where your bottlenecks are. At work we use Maya/VRay. We have some complex-ish environment layouts that are a bitch to work with because we don't or can't optimize a lot of the scene content with instances or proxies. I would love to be using Solaris for those projects because of how well instancing and proxies work in USD.

Unfortunately USD in Maya/Bifrost is still SHIT. I don't know wtf Autodesk has been doing all this time but it's still nowhere near usable for real work. Without dedicated technical directors you won't get far. Matt Estela said it best when he called every USD authoring tool outside of Solars glorified kitchen.usd viewers.

But yeah, use Solaris. Some of it is still painful, because it is exposing so much of USD to the user and also because it still needs more polish, but I'd say it's worth it for them workflow gains.

>>923446
>Can I ask, why not just use the component builder workflow to make your variants?

Because I'm following the official tutorial from Pixar, another tutorial from CG Forge, and the big dog, Matt Estela's wiki. I've made my hip as clean as possible, and its still cant get it to work. MEstela doesnt even mention the component builder workflow nor does that link you gave me include any hip. To add insult to injury, I posted this question on sidefx board, detailing my steps, but they didnt approve my post because everything needs to be moderated over there, despite me being a paying customer who just reupped sub and the post being very nice in tone

>>923455
I finally figured it out thanks to CG Forge...my variantblock_end1 was pointing to the grid instead of the shader. Now I can go back to 19.0

>>923459
and my final post on this is that the pixar tut i first mentioned, at 14:47 is actually doing what i first did and didnt work ie have the primitive geo in the primitive path and not the shader. And, it works for them. So, this is why it was so confusing and frustrating since nobody includes hip. Im sure you all think im just an idiot. Well, pixar did it the way that definetly no longer works any more

>>923446
I use o lot of heavy unique geometry and have it being displayed at same time. Even scattering sometimes is painful and I need to hide the bounding boxes.
I really just want to be able to assemble my scenes without having to look at a bunch of boxes.

>>923409
>>923459
>>923462

hey anon,
Sorry, i was busy with work.

Glad You got it figured out with the veriant end pointing to the shader.

What alot of those tutorials fail to mention is that they are using assembly usda files (which brings 'Asset and Lookfile' under same umbrella, whcih makes the asset tree combined, which was probably what threw You off.

>>923446
for Renderman users, and if they only use Maya - USD scene files are unrenderable, unless you use Arnold( dont know about RS)
Vray needs update for autodesk' usd0.19

in our pipeline, we use Maya for animation only, and then send the stuff into both Katana/Houdini, depending what else the VFX folk need to do for the asset.

Going from Maya where I did uv mapping to Houdini with alembic my UVs dont show up and I get error

>houdini alembic import invalid attribute specification: "uv"

when trying to use uvlayoutnode.

I hear that this is because hou wants uvw and maya exports uv. But, I dont know how to correct this nor where to correct this. What should I do?

>>923538
exported a cylinder from maya 2020.4 as abc
only option i selected was "uv write".
came into houdini fine.
convert node to actually manipulate them, otherwise they're primintrinsics.

>>923581
It opens in houdini fine but with the invalid parameter uv. According to reddit this is a real problem. Try 2023.

What did you mean by "convert node" ?

>>923585
Also, i am not just importing one cylinder in my abc, but multiple because i have a character with multiple parts that belong together that i UVed

>>918181
>footwear
?????

>>923585
>>923586
1. i am not updating my maya. don't ask people to do this, it's rude.
2. i used the cylinder as test geo. maybe you should too.
3. if you can't manage to get a cylinder over without issues maybe tell us what you're doing
4. according to reddit i have 16 inch penis
5. i mean use the convert node

how did you guys get started on houdini? suggestions for a beginner project?
By the way, I'm using apprentice and I don't like to pirate. How fucked am I? Will I melt my CPU trying to render since there's no native GPU support and apprentice disallows 3rd party rendering engines?

>>921387
didn't open the image or click the link but you should kill yourself NOW

>>920349
my guess, just based on the nature of the show they probably thought that they'd rather be safe than sorry if they ever needed simulations for some episode script. well, if you're correct. I can't find anything articles confirming that though, only that the studio that made jimmy neutron started using sidefx software for later features (ant bully, specifically)

>>918908
LOOOOOOL

>>923717
>how did you guys get started on houdini? suggestions for a beginner project?
to get started you do a series of tests and save those tests into HDAs and then string them together and build a library. Wa-la 6 months later you're making 100k+

>>923720
Just test random shit or do you have a suggestion for neat effects a beginner can do? I do compositing with Natron and Vegas and such so anything I can slot into the background of a video is cool even if it would look lame on its own.

>>923721
i cant hold your hand, you'll just have to use your imagination. If you cant self motivate you'll give up very very quickly.

>>923727
I was just asking for suggestions, faggot. If I couldn't self-motivate I wouldn't be doing vfx at all.

>>923728
you wont get very far with that attitude and like you say, you are a beg

>>923717
your first project would be to find out about karma xpu

project 1: sops based. some sort of procedural model of a prop.
project 2: pops based. i dunno magic or some shit.
project 3: vellum based. cloth. strings. stuff.
project 4: pyro. make ze explosion.
project 5: rbd. make something fall down cuz you made ze explosion
project 6: flips. spend 3 weeks waiting for cache.
project 7: terrain tools.

congratulations you've now touched a lot of houdini and understand almost none of it. you're on your way.

>>923464
What renderer do you use anon? If that's the only issue then maybe just take advantage of your renderer's proxy workflow, ie: V-Ray Proxies, Redshift Proxies. They allow to have a lightweight, decimated mesh as a viewport representation.

I still think learning Solaris is good, but it is almost like learning another DCC on top of Houdini, so maybe it's overkill here.

For anyone doubting if Houdini is worth learning:

Henning Sanden
@henningsanden

Sidenote: While film and commericals IS moving away from Maya, it's not moving towards Blender but instead Houdini. If I was a student today, I'd 100% be learning Houdini.

If you want a future-proof tool, this is it.

Stay the course brothers.

>>924353
y'know i don't hate the flippednormals boys or anything, but the industry experience they always talk about is working on one of the pacific rim movies - but a lot of their non-intro tutorials are about human-esque character sculpting and, like the results just aren't that impressive.

also lol, kinefx is never going to replace maya.

>>924360
actually i'll add that houdini can't even reach maya's mediocre modelling and uv'ing abilities for traditional modelling. you make your modellers and animators work in houdini for a week half your workforce will an hero.

some overseas title

Beginner here looking for some tips. I've been working on a simple scene in Blender geonodes that I started to think would be a better fit for houdini:
Basically I have two metal pipes (A) which are part of a biomechanical limb, with one pipe nested inside the other, moving up and down like a piston. Then I'll have muscle fibers wrap around the limb (B).
Simple enough, right? So here's my problem: I'm making the larger of the two metal pipes with two cylinders, one (the wider of the two) being the material, and the other being used to cut the middle out via a boolean operation. The boolean operation doesn't work. There is no change to the wider cylinder. I have both cylinders set to mesh mode, endcaps on, and the boolean is set to subtract. I have the boolean node selected for view. Why isn't it cutting?
Sorry for the basic question, I'm very new and may have bitten off more than I can chew for a first project. Any links to relevant tutorials would be nice though.

>>924521
Okay just realized I can turn endcaps off and extrude outward, but I would still like to know why I cant cut a hole in the endcaps with a boolean node if anyone could tell me.

>>924521
works on my machine, if this is what you wanted.
thanks for the useless diagram tho.

>>923720
consider doing stuff like sparks, rbd bullet hits, smoke trails, chimney smoke, simple realistic looking fire. this is the kind of stuff juniors are given at least in our mid size studio

>>924527
>works on my machine, if this is what you wanted.
what the f? I guess I should've played around with the settings a little more or something
>thanks for the useless diagram tho.
yw

>>924529
i changed no settings on boolean, big cylinder just has end caps on. small probably should, but since boolean is treating it like a solid it just adds them it itself
use polyfill is you want better endcaps btw.

>>924532
>use polyfill is you want better endcaps btw.
thanks for the tip my man

>>924521
okay so I have the pipes done, can anyone give me some pointers on how I might wrap a vine like object about this piston? I'm guessing that I would use vellum if I want the vine/tendril/muscle to flexibly move with the piston, but how do I get it to contour about the surface? Will I have to shape it manually and then choose points of contact where it sticks, or is there a procedural way to set the contour?

>>924566
m8, you maybe need to do some more tutorials and learn about the options at your disposal.
there are bunch of way you could do what you want, but here:
https://www.youtube.com/watch?v=2NiV3EyK5xc&list=PLXNFA1EysfYkjtSoBdZ53TgBIGjMlFDga

simple vine generation set up.
i'm not going to spoonfeed you a solution to the simulation part because it's something really basic that an intro to the types of vellum constraints would cover (or like look at the manual)

>>924610
Sorry, my bad, I suppose I need to get used to the fact that Houdini has more detailed general guides and less hands-on beginner tutorials compared to Blender, so I'm struggling to adjust. I'll stop with the dumb questions. But thank you for the link.

>>924685
there is too many options in houdini to approach procedual stuff, learn the tools like anon before told You, nad eventually you'll be figuring stuff out yourself quicker.

Does houdini have any addon like Maya's Animbot in tools for animation managment?

I feel like I asked this in this thread but can't find my post so I guess I'm crazy but here we go:

Can anyone here tell me if this is possible: I'm searching for a way to automate the way the clothes of a character for a game moves during some attack animations. Do you think I can bake clothe animation from the cloth simulation from Houdini into bones that are going to be in the long vest or whatever piece of clothing my character will wear. I don't know if you understand what I'm trying to say.

no.

much bigger problem. learn something else for 6-12 months.

>I aim mostly those exploding, decaying, and desctruction effects that's hard to do in real life.
houdini is the ideal package for this, but see above.

>>926859
>something else for 6-12 months
what would you recommend? Like Blender? Blender is completely free so I can do that. If there's something else you would recommend let me know.

>>926861
blender's fine. don't spend too much of your time focusing on any one discipline (modelling/sculpting/animation etc) for the first few months.
do tutorials and very small projects and move through stuff quickly so you get a flavour of things.
all those skills will transfer over; plus houdini is bad at a lot of traditional /3/ stuff and blender complements it quite well.
you'll be using both in the future. glhf.

Neat! Got any examples of problems where it fails?

it's pretty fragile. here it's declared both functions improperly, tried to return an array in the second function and funnily tried to use python syntax to append a value to an array.

i would be laughing at how dumb the robot is, expect it took me 2 minutes to fix the code and it works.

>>928002
Idk, the result is pretty but certainly not VEX, probably not even novel as Github returns 22 results for "torus knot".

I'd still use it as an algorithm search engine, I wonder if it can digest papers into pseudocode.

>>928006
yeah i hit try again a couple of times on the same question and got nonsense-code

it definitely doesn't 'know' what VEX is, but i think it has some sense that it's a c-style language so it's probably borrowing stuff from thinks like c and javascript.

i asked it to write code for a mycelium network and it just flat out said no, can't do it, too complex lol

...why doesnt Karma have SSS on gpu? Even blender can do it, for almost 10 years now. What gives?

>>929398
? Karma XPU supports randomwalk SSS in 19.5

It's also worth remembering that it's a beta renderer at this point. Renderers take a few years to develop and many more years to mature. They don't just pop up full-featured overnight.

is there a way to make a for loop skip to the next iteration if a node inside the loop is taking too long? i.e. set a timeout condition.

How to learn Houdini

The Continuity of Splines
https://www.youtube.com/watch?v=jvPPXbo87ds

How does Houdini compare to ziva vfx for muscle and fat simulation?

>>930546
Houdini is Training wheels off .
Ziva is training wheels on.

>>930578
Dont listen to this guy

Ziva fx is extremely difficult, even with 10+ years experience. You will need to be an expert in multiple areas to use it properly. Hollywood puts their brains together in meetings and choose to use it in big blockbusters including Godzilla vs Kong.

>>930584
Brainlet take.

>>930590
Fuck off. It takes weeks to prep a single character using ziva. Its been determined to be a better fit since it has industry leading tools built specifically for muscle simulation. If you dont use it you dont get the tools. You look at examples from many years ago (zeke the lion) and they are tar beyond what has been achieved with houdini. Some of the people who wrote ziva are ex.weta. They are proven in the biggest productions

>>930611
Kek, what a lying rat you are. Stop spreading this shit, you faggot. It's clear that you don't work in the industry and are just lying and parroting shit from others.
Just shut the fuck up.
Incredible what kind of absolute genetic shite is crawling around here. Fucking shithead and he pretends to know. Holy shit, you are the reason why people have no clue about anything and are spreading shit.

>>930613
Fuck off

>>930611
>>930618
Lmao,
lol even

GTFO from houdini thread glowtard, its clear You want to use training wheels atall times, fuck off.

>>930622
>glowtard
>training wheels
the court rests

>>930546
Be careful using the Z word on this board. It summons the schiz.

>>930625
>ziva, the brainchild of multiple weta digital employees summons "___" as their claims of what the plugin can do cannot be refuted, instead just insulted with "training wheels" etc, despite rigs taking weeks to months to build and being used in multiple blockbuster films with major action

yeah

>>930627
whatever ziva can do, houdini can do better. simple as
now go back to your own thread faggot.

>>930628
dude, i use houdini daily. This is my thread. Houdini does not do it better. It has the same solver, but does not have the tools for muscle simulation built in, as previously mentioned. Fuck off back to learning

>>930629
>I use houdini daily
>It cant do it better
I rest my case, go back to learning.

>>930630
The solver is exactly the same and they are missing muscle simulation specific tools. Are you retarded

>>930631
>works in the industry
>doesnt have custom made tools by industry
lmao,
lol even

>>930635
You think being in "the industry" means you get xy and z for free and you can use them at home and take them with you when you leave, huh, dumbass?

Heres a protip: you can extend ziva. It has an api. You can make new nodes. People in hollywood cinema choose it for a reason. It is a custom tool in itself

>>930631
They solvers are not the same. Ziva uses proper FEM, Houdini's muscles use a XPBD approximation (vellum),

>>930673
noone said anything about bringing it to home, fucko - doesnt change the fact that houdini is better, and You know it - go and suck some of tha Ziva cock , make sure the skin goes with your sucking force.

>>930697
he already outed himself as an idiot, no need to point it out.

>>930702
>noone said anything about bringing it to home, fucko
so you admit you cant bring your tools home, you cant bring your tools to the next job and now you're admitting that you're not even using a proper FEM solver? And even Sidefx themselves, with their finger on the heart of the industry cant muster anything more than sloppily controlled, slop looking demos while Z has for years had incredibly real looking demos?

gg ez

>>930702
I think both of you are retards.

>>930706
Keklmao, tell me that you don't use houdini, without telling me that you don't use houdini.

>>930721
i use it for its main feature - solaris with redshift

>>930724
>main feature
>lists beta features and 3rd party renderer

lmao i fucking knew the glowtard doesnt know shit.

>>930706
Question was, pajeet - whats the difference, the difference is - you are retarded and fail to see it, stop turning argument points around

gg ez

>>930741
All you can spew is hate. I fucking knew it! I am a payong houdini user for many years as much as you! Fuck right off, kid!

>>930746
Come on, don't get pissed at some shitty software argument.
If you can do great stuff with Houdini, that's great.
Take it easy and don't lose your calm.

>>930746
>I am a paying customer

doesnt matter -you still suck, just becasue you pay for it doesnt mean you are good at it.

>>930860
Why would i "suck" when i know how to manipulate USD and render in solaris? You know what, dont answer that, idiot. All you can do is a slow circle jerk.

>>930878
you answered your own question.
be sure to use the main features ofhoudini by using solaris and redshift, this is such a big core of houdini! its 90% use case!

>>930894
>noooo, dont use the software the way you want to use it!
>noooooo, you have to use pyro and water sim even if what you're doing doesnt call for it!! And even if you dont have nearly the hardware for it!!!
>noooooooo!!!!

Stay in your lane.

>>930945
i accept your concession

>>930945
Anon, you do realise You were the one trying to move goalposts here right?
You started with Simulation talk, then started strawmaning arguments.

Please go away from houdini simulation talk and never post again if you are trying to be stupid on purpose if your 'main purpose' is lookdev.

is anyone using Houdini for regular stuff?

Happy New Year Houdinis

What is everyone's plans with Houdini for this year?

>>932131
i will spend a day finally learning kinefx constraints
i will dabble in kinefx muscles
i will incorporate constraints and muscles into a procedural n-legged kinefx walker
i will spend a lot more time with pyro and volumes
i will try to use karma xpu as my default renderer for all personal projects

Anyone here use geonodes? I'm a blendlet trying to produce a certain effect in geonodes and my method is suboptimal (it's a pain to improve and runs hella slow). I'm wondering if there's someone here who could tell me if there's a way to improve my methods in blender, or if I need to jump to houdini (apprentice (watermarked)).

>>932786
what's the effect?

>>932805
I know it looks pretty bad right now, but I had planned to add details with more booleans and then some stuff in the shader editor. Can't really do that though because it runs extremely slowly as it is. Basically I want to have a character grow extra eyes on a region of their skin, so I have an area where I've scattered some points, and based on their proximity to an invisible plane, they will push up a region of the skin, pull down a boolean to slice that area, and also push up the eye meshes. It takes ~10 seconds to update a frame right now, so adding new nodes or even changing a single value is a huge pain.

https://www.toadstorm.com/blog/?p=942

nice write up, henry. tyvm.

https://www.sidefx.com/docs/houdini/vex/functions/fit11.html

when the fuck did they add this

>>933087
>there's now FIVE (5) redundant fit functions
sidefx please fire suresh

>>933091
i don't mind this one t bh. who tf needs fit10 tho.

beginner question: how to scale particles by their distance from the origin? I have an L system, and I want the points to shrink as they leave the base so I can use a sweep node later.

>>933522
https://www.sidefx.com/docs/houdini/nodes/sop/edgetransport.html

I can't remember if distance along geometry works for curves

If you just want distance as the crow flies then use distance() function in a wrangle

Once you have distance you can use attribute remap to remap to a new range and set as pscale
Not a big fan of that node desu - you can do a more procedural set up by getting min and max distance by using attribute promote and writing a few lines of vex

>>933535
>you can do a more procedural set up by getting min and max distance by using attribute promote and writing a few lines of vex
Oh? Should a beginner like me be using Vex?

>>933537
Yes. Just pick bits and pieces up as you go.

Does anyone know how to put this custom vector from my polyframe in the direction channel from the group node? i tried v@custom or @custom but they don't work

>>933589
Use a VEXpression like prim() or point(), note that VEXpressions are not identical to VEX functions with the same name. I think in your case you want prim(0, "custom", 0, 0), prim(0, "custom", 1, 0) and prim(0, "custom", 2, 0) in the corresponding xyz channels, I'm remembering this offhand and can't check.

>>933591
doesn't really work I also tried putting the location of the node instead of zero like in the example of the prim() function but didn't work either thx for responding tho

>>933594
Ok, too bad. VEXpressions are gay anyway, try this in a primitive wrangle:
i@group_myprimgroup = degrees(acos(dot(v@custom, prim_normal(0, @primnum, 0.333, 0.333)))) < chf("angle_threshold")? 1 : 0;

Why are OD Tools, MOPS+, AXIOM 3 not cracked yet?
Are they the X-Particles of C4D?

>>933600
they're reasonably priced and one-man operations
not essential either

>>933600
there is a free version for Axiom 3 available that is feature complete - I am using it right now.

if i could have one feature in houdini 20 it would multi out wrangles so i could write to 4 geo streams without having to duplicate geometry into the input 0 stream

Is houdini viable for modeling, or am I asking for pain?
I can work pretty well in Blender, but I do often wish for a more parametric and nondestructive modeling process

>>933630
it's probably the best tool available right now for procedural modelling but beyond super basic stuff, the process becomes very alien to traditional modelling.

trad modelling is absolutely awful in houdini, but there is a blender bridge someone made:
https://twitter.com/enoni_de/status/1585962526566752256

Im trying to use my group in a switch and switch inputs if it is empty or not But it says it doesn't recognize the group and the switch doesnt work. I also tried already switching the inputs but it still doesnt recognise it for some reason

>>933880
Check out the Switch If node, you can directly test element count in a group.

>>933896
yeah thx I got it to work

there was a way to access matrix components in an array like fashion or am i thinking of python?

eg
float z = 3@transform[2][2];

getcomp is really cumbersome.

>>933951
edit fwiw i'm just trying to get the z axis out of the 3@transform of a kinefx joint.

>>933951
There is, 3@m.xx 3@m.xy 3@m.xz etc.

>>934014
works a treat. thanks, champ.

>>933632
If blender is supposed to be the FOSS alternative, why doesn't houdini have the same capabilities for traditional modeling yet? I mean, certainly it would be practical to include, no?

>>934047
fuck off, m8

back to mac or no?

riglookat()

>>937377
Very cool, VEX was sorely missing these kinds of fundamental geometric queries. Would be nice if the segment and triangle functions also returned the barycentric coordinates of the projected position like xyzdist does.

>>937394
could you give an example of how one of these new triangle functions could be used? i'm a geo processing brainlet.

These are very handy for moving along geodesic paths, or in general any problem where you want to travel along the geometry and not accidentally leap to a topologically disconnected part of the surface.

>>937404
interesting... i think.
you don't see a lot of this kind of geo processing/traversal in houdini learning materials - i think i've come across it only on stuff talking about half edges - a jake rice talk and a juni video i think.
is stuff like this a lot more commonly used outside of fx? i'd like to learn more esp about its applications so if you could nudge me in a direct it would be appreciated.

Houdini for Apple Silicon now Gold

SideFX is excited to announce the gold release of the Houdini Apple Silicon build to coincide with the H19.5.534 production build. The Houdini Apple Silicon build is built natively for macOS arm64 so Mac users can take full advantage of the power of Apple silicon M1 and M2 chips.

>48k+ machine or 8k equivalent PC machine for the task.

hmmmmm

Any recommendations for a motion graphics focused introductory course? Currently looking at the Houdini Procedural Foundations course on learnsquared but looking for other suggestions

>>938162
a. you can pirate this course
b. it's old and like it's nice to know this stuff, but there are newer workflows now. do the course in like 8 months.
c. it's awful as a beginners course
d. it's even worse as a mograph course

mark fancher's stop being afraid of houdini is a much better mograph-y course intro thing, but as with all houdini intro courses it has an impossible task and i don't know if anything will really sink in. only one way to find out.
start with that one or the hipflask sops series because they're boring.

do sops > particles/pops > rbd > smoke > flip > etc in that order

>>938209
oh also, stop being afraid of houdini is also older and there are newer workflows for some things now - the old stuff all still works and you need to learn it eventually (updates are a lot about streamlining things at the cost of some flexibility), but just know that you'll need to follow up. this is a constant problem with learning houdini - the updates are meaningful and come at a ruthless pace.
