Kai Stavginski has been a Senior Technical Director for SideFX Software since 2014. In that time, he's mostly been busy in the areas of shading and fur tools. He started in the industry as a generalist in 2004, spent some time as a rigger for an animated feature and then created VFX for major Hollywood blockbusters for several years. He used Houdini to get the job done and now uses his extensive industry experience in his development work on the software itself. less

Simulating long curly hair in vellum Sept. 24, 2024, 2:45 p.m.
Yes I think this requires some extra constraints, basically something between the curls within a hair, to keep those together.
I think pure curls set up purely as individual vellum curves will always unravel.

Toucan Groom - Crash after de-intersection? Sept. 4, 2024, 3:02 a.m.
Ok I'm actually getting a crash in CPU mode now. So there's likely to be a bug - the CPU driver is generally better at catching those.

I can cook the whole setup here. My houdini sits at 34GB RAM usage by the end. GPU memory spikes to 5.4GB during deintersect.
If you're running out of RAM it might help to cache out an intermediate step and reload houdini.
Or there might be something system specific going on. If it fails at Feather Deintersect its more likely a GPU thing, maybe a bug in the OpenCL code that only happens with certain driver versions. That's something we've certainly seen (fun). Got any more info about your system?
Can you switch your OpenCL device to CPU and test? You can do that in Edit->Preferences->Misc.
