Hey,
I have a weird problem, on my scene when I render the RC object in Vray CPU eveything is correct, mesh and material : render is matching the viewport.
When I render the same thing with Vray GPU some panels are strangely switching materials ID (from 1 to 2 in this exemple) : see the attached JPEG. I know that because when I convert the RC object in Mesh the problem occurs again and I can see that its switching mat ID.
It's very annoying considering I'm supposed to render the scene with GPU for time management.
Windows 10
3DS MAX 2019
Vray Next v2
RailClone v 4.1
Do you have any solution to this problem ?
Regards.
