4.2 Preferences System tab crash with Intel Arc on Windows 11

5522 seems fine, so I'll be sticking with that until there's a fix for the memory fallback. Thanks!

New Auto Smooth modifier prevents shape key export

The resolution in #93551 for exporters appears to be "I hope" which IMHO is not a very good strategy when it comes to software ;) Also the task for double checking on the exporters was not…

4.2 oneAPI "Embree on GPU" (HWRT) no hair strands in viewport

We can reproduce it but we haven't fully root caused the issue yet.

  • Hair do appear in preview with other scenes like Koro.
  • Increasing BVH build quality has no effect.
  • I've…

4.2 Preferences System tab crash with Intel Arc on Windows 11

Updating to 5762 appears to have fixed it. You may want to document as a known issue as the driver version I was running is only a month old. It may also have involved multi-GPU as I have my iGPU…

Cycles deforming curves disappear when using persistent data

Updating to studio driver 555.99 did not resolve the issue. I still get disappearing curves. I'll see if cycles debug log says anything interesting.

hair sculpt collision doesn't work well with real scale human head.

A PR for the UI or for the default distance? I don't have the knowledge to make a UI change. I agree though that it would be very nice to have it as a UI value. Right now it's hardcoded in the…

hair sculpt collision doesn't work well with real scale human head.

I recompiled Blender with the old radius of 0.001f and it works much better. Curve collision is useless in current form with 1:1 scale.

I don't observe any huge freezing issues. The only…

I've been poking at this, mostly in the code in curve_intersect.h, which has the intersection code for both rounded ribbon and 3d curve curves.

Comparing it to 2.83 in geom_curve_intersect.h…
