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

H20 Feather generation findings and questions. Nov. 30, 2023, 1:34 p.m.

Kai, I could not get the new parting line algorithm to work with feathers.
Can you perhaps post an example of how this is supposed to work?
That's a bit worrying, does it work with the old one? (Either old build or disabled via the env var) ?
In theory there should be no change necessary on your part moving to the new algorithm, except maybe make sure that you have point normals on parting lines. (Should do by default with the Guide Partition SOP)
feather barbules polygones with uv ber parb instead of tubes Nov. 24, 2023, 2:49 a.m.

Is there a plan to add a 'feather bsdf' for use on polygon strips or curves that models the barbules statistically? I always found the use of anisotropic specular/translucent refraction shader to be a bit unrealistic on cards and the hair model doesn't really represent the fine barbule structure.
Not quite a plan yet, but sounds like an interesting thing to pursue. I'll discuss this internally.

It does crash anytime I try to increase the hairgen count. Not sure if it happens on your side, but here is my file saved before the crash.
I believe this should be fixed in 20.0.535
