Oh, and maybe it would help to update your drivers. 472.84 is quite old, I had some trouble before with mismatching drivers / Optix version. Caused all kinds of strange render bugs.

Steffen Dünner (SteffenD) added a comment to T100164: Alembic import with animated normals causes incorrect shading.

Just gave animated UVs and normals a try by animating the UVs and normals of a simple grid in Blender, exporting it to Alembic and re-importing it. They both work.
Abcinfo for the animated normals looks very similar to the one coming from Houdini. I wonder why only the one coming from Blender has proper animated normals:

I don't know. In a default layout try dragging the horizontal separator between the Outliner and the Properties up and down and compare it's responsiveness to dragging the vertical separator between e.g. the Outliner and the 3D View left and right.
If you switch the 3D View to e.g. a Shader Editor, everything is smooth again.

Steffen Dünner (SteffenD) added a comment to T95895: Cycles: Different results of the same scene on different computers.

@Juan Gea (juang3d) You are of course right. I never actually build hard surface stuff from SubDs that's why I didn't bother rendering my example ;)
But the rest is still true: Custom normals and SubDs aren't best friends. Still funny why the GPU viewport shows this result.

Steffen Dünner (SteffenD) added a comment to T95895: Cycles: Different results of the same scene on different computers.

In my experience OpenSubdiv (or subdivision surfaces in general) don't use custom normals because the algorithm itself is responsible for generating its normals on the limit surface. If you want a perfect cube, use creases.

Steffen Dünner (SteffenD) added a comment to T95895: Cycles: Different results of the same scene on different computers.

The results are different in 3.2 master depending on whether GPU subdivision is used or not. GPU subdivision shows the faceting (coming from the fact that the mesh has custom split normals and is set to flat shading, I guess that GPU subdivision doesn't handle this case correctly?) while non GPU renders smoothly.

Steffen Dünner (SteffenD) added a comment to T95945: Alembic not importing velocity.

I just gave some point clouds with velocity vectors coming from different source software a try (in Blender 2.93, 3.01 final and in 3.2 master) and never could get motion vectors to import. I also tried animated point clouds with static and changing point counts and a (particle) point cloud exported from Blender that successfully exports its motion vectors to an Alembic but doesn't load them back in. They're actually there, I confirmed it in 3rd party software.
So apart from a patch by @Kévin Dietrich (kevindietrich) I think Blender never supported velocity on points / vertices?

Steffen Dünner (SteffenD) added a comment to T95895: Cycles: Different results of the same scene on different computers.

While trying to reproduce the problems I noticed that there's quite a combination of things that can influence and break the shading:

  • There are custom split normals on the geometry
  • They are set to flat shading (which should ignore custom normals IIRC?)
  • "Auto Smooth" is on so that custom split normals are even used
  • Custom Normals are used in the SubD modifier
  • Creases are used in the SubD modifier

Steffen Dünner (SteffenD) added a comment to T92960: Objects with GN modifier become very slow to animate.

Thanks for the explanation.
Would it be somehow possible (without breaking too many things) to treat objects with completely muted / disabled GN modifiers like objects without any GN modifiers at all? This would already make a simple workaround in my current project a lot easier than it currently is. I could just disable the GN modifiers during the animation phase and switch them back on whenever I render the scene,

@Steffen Dünner (SteffenD), not sure if an empty Geometry Nodes modifier can cause the same underlying issue. Please create a separate report for that.

I was about to post a similar report and found this one. In my case the massive slowdown happens with a "Set Material Index" node.
