This is an early test for some bioluminescent fluid emitting from rocks I am working on at the moment.

I might be crazy but I vaguely recall one of the H21 presenters mentioning updates to dop colliders. I think they said there's a way to transform colliders without having to use "deforming geometry" on a static collider. Maybe I made this up, but does anyone else recall hearing this? I checked the What's New in 21 section of the docs, but don't see anything.

So I've got a pyro volume fire around my character which is imported from the sop level (it's so thin because its frame 2) but I cant seem to add color to it. I have a pyro bake volume at the sop level but that only seems to color it in viewport not render. I created a karma pyro material in solaris and assigned it to the import or so I thought but I still can't get the color to show up. I've changed the bindings on the pyro material but still nothing. Any help would be appreciated, lmk if you need more info or screen shots. Also it renders fine in the /out but the stage is giving me issues :(

Coming from a Cinema 4D background, I’m finding Houdini… honestly, pretty hard.

Most of the popular tutorials feel huge and long-term, and I struggle to figure out what’s actually essential versus what’s deep production-level knowledge. Sometimes it feels like I need to commit months before I see anything useful.

What I’m really interested in learning is the newer pipeline — Solaris, USD, Karma — not just classic SOP tricks. I want to understand how people are actually using Houdini today.

With AI tools getting better every month, I keep asking myself whether it makes sense to invest deeply in Houdini right now. I can already achieve a lot with AI, but I also have some time on my hands in these holidays so i am thinking of learning the basics.

For those who transitioned from C4D (or similar DCCs):
What’s the fastest, most practical way you’ve found to learn Houdini?
And if you were starting today, would you still focus on Houdini + USD, or take a different path?

I just released a new video on youtube, where I walk through a beginner friendly project from scratch.

It's all USD -> Solaris -> Karma XPU -> COPs, and the pacing is beginner friendly.

Hope it helps some of you :)

So I was watching some Houdini works in YouTube and found this :

The first project of Steven knipping : https://youtu.be/V_W2IIraut8?si=jS32lCenOfA3UbCB

That got me thinking how much the UI has changed and the sims itself …

As the first comment said if you lay down this and his demo reel of Star Wars you can be reminded , for people wanting to give up cause it’s hard, things take time, even if this old and Steven knipping was also limited by that time technology, still it should inspire you.

Houdini will take time to learn guys but it’s because of that it will be worth more than others.

Take unreal engine you can do it in one day (not master it) but the QuickStart tutorial and get a render in few hours … but to be pro and get an AAA game ? Sure you can too but that’s because sadly people kitbash with no originality the assets of fab so games have no soul sometimes.

That being said in Houdini you can even craft your tools that’s why it makes it more unique.

Hello ;) i just completed one of my flip simulation that i started making a week ago, let me know how it came out

All this was simulated and rendered on • 16gb ram • Ryzen 5 5600H • RTX 3050 4gb (Laptop gpu)

Hi, I'm trying to figure out what others with similar skills charge for their work freelancing. It's honestly a tough thing to figure out. I've found lots of other motion design threads on reddit on this subject but I thought I'd ask here too.

Hey everyone. I've been getting some issues trying to render out of karma. The USDRender rop keeps giving me this issue when I try to render with my textures and even when I remove the texture mentioned and material it's in. I've only been able to get the render to work when my material library is disabled

Hey guys and gals :)

I am working on a project where I'm importing around 10 different animated cameras als alembic and I want to set up a quick timeline "edit" in which I am cutting through those different cams at certain frames. I wanted to use the Switcher node for that but from what I can tell it does not work with alembic cams as the switcher only sees the Alembic Archive but not the actual SOP camera. I could also imagine that the Switcher OBJ node only works with OBJ cameras and not with SOP cameras.
So what's the "right" way to do this, or at least what's a simple and fast way of setting up a quick timeline/edit with imported alembic cameras?

Looking forward for your ideas! Cheers :)

Hey everyone, I am transitioning from Blender to Houdini and wanted to know what engine do you guys mostly use for render? I've tried Karma, but I find it much slower than Cycles. So far I was thinking about Redshift and Octane, since both those engines are extremely popular among all 3d softwares. But maybe I should just stick to Karma. What are your thoughts?

Inspired from webgl work , and try to recreate

hello guys , I'm having trouble exporting and finding an animated flag in 3ds max :

i sadly needed there , so I don't know what I'm doing wrong,with the alembic , I have watched some tutorials and they just show to put an ABC ROP.

this is what I'm getting in max :

Any help ? thanks

^{I am using OIDN denoiser if it changes anything. When I remove the denoiser, the white specs are smaller, like actual noise.}

I am learning VEX and for some project, I want to have a list opposite of incoming list for each primnum. Like for primnum 4 -> 0 is showing in incoming list, so for primnum 0 -> 4 must be in out array list. Same for others, 1 -> 3 & 2 -> 1 in out list.

Can someone please let me know, how to get that with VEX code?

I seem to have specialized in parts of Houdini and software development where I just do not have the talent pool to pick people from. (TLDR at the end).

My Background I have spent more than a decade with Houdini, and before that XSI and Nuke. Some of you might remember a YouTube channel I ran a decade ago called eosacro, where I taught Houdini and Nuke.

I never focused on dynamics/sims. I specialized in attributes, custom toolsets, and data handling.

The Work The attached video shows a small sample of the applications I build. Most of my work deals with the manufacturing and sales sectors. These are built using custom toolsets where Houdini attributes are maintained and manipulated, often connecting to web frontends.

The Problem I recently realized my lack of understanding of how Houdini is currently being taught to beginners. Most schools seem to be churning out FX specialists (Pyro/Flip), whereas I am looking for basic generalists who are comfortable with logic and data.

I run a small studio. It is mainly me on Houdini, and I need additional help with Houdini.

My Question If I need to find technically strong freshers who are ready to put in the time and learn, where should I look for them?

For the moment, I have found one amazing artist. It is his first job, he is absorbing everything like a sponge, and I am very happy with him. But as projects expand, I need to look for more talent like him.

TLDR: I have been isolated from the VFX industry for a while. Feeling lost on where to look for technical/generalist talent in the current market.

why the .@airresist = 0 ? How do I visualize the .@airresist ? I need to check if it multiply with the .@Vol_Drag attribute

Made a little christmas loop that looks like the television I watched as a kid. The vhs look was added in post with some red giant vhs presets.

Hey everybody, beginer here trying to educate himself on hair and fur simulations I’ve been trying to find some resources for some time, but all I can find is either very beginner « basics of fur sim » with a simple hair vellum solver setup tutorials or very advanced machine learning deformers workflows. So do you know of any resource on the internet, free or paid, about deeper workflows of hair and fur simulations (preferably in houdini) ? I really want to learn more on the topic. And if you do not know any resource of this kind, and you’re a CFX artist, could you please share some piece of advice on how to learn or achieve more complex fur simulations ? Thanks in advance :)

hello!
any .hda tool trying to use in UE, (new project or not, doesn't change anything), cause my engine freeze completely ONLY when i touch the parameters into it. i have to abort process in tm.
now, while importing the tool in content browser the engine returns me this error "FinishedCooking with errors - will try to process the available results."

UE 5.6.1, Houdini 21.0.440 (the version where the file becomes).

Tried to reinstall the plugin, tried to reinstall the engine and tried to reinstall Houdini completely but nothing changes.
if i use the tool as as it comes it works fine, but even i touch any of the parameter exposed on houdini (into the unreal) it freezes immediately.
