vray gpu override (rhino)

[citro3101]

I noticed that material override on GPU using Brute Force/Light Cache, causes Gi bleeding. But (Brute /Brute ) will does it correctly. CPU no bleeding in both modes.

Is this an bug ?

Hello citro3101,
Thank you for posting!

Can you please share which exact V-Ray build you are using (V-Ray>Help>About V-Ray)?

I made a similar setup to yours with V-Ray 7.00.03 and I do not see any differences between CPU and GPU with Brute Force or Light Cache.



Perhaps there is something different in your project - could you please share it? Make an archive with the Pack Project tool (V-Ray>Pack Project) and open a ticket (request type: Product usage questions or issues) where you can upload it.

Thanks!

Thank you for the file! Apparently I was checking global Material Override instead of Override material. I will do some tests and update you soon.
