Bug in GPU rendering mode!

Hey everyone,

I’ve run into what looks like a bug in V-Ray GPU for Rhino and wanted to check if anyone else has seen this or has a workaround.

Texture remapping doesn’t seem to work properly when rendering with V-Ray GPU. The same scene renders correctly with V-Ray CPU, and texture mapping behaves exactly as expected there. I also tested a similar setup in Blender using GPU rendering, and it works fine, which makes me think this might be specific to Rhino.

So far it looks like:

  • V-Ray CPU in Rhino → works correctly
  • V-Ray GPU in Rhino → texture remapping broken or ignored
  • Blender GPU → works correctly

Has anyone experienced this issue? Is there a known limitation with texture remapping on V-Ray GPU in Rhino, or could this be a bug?

Any help or confirmation would be really appreciated

Hello, miha_jereb,

Thank you for your report and the scene. We reproduced the issue with the official 7.20.02 build and verified that it is not reproducible with our newest builds. The issue will be fixed in the next V-Ray for Rhino update.

Kind regards,
Iva
