VRAY GPU ignores VRAYLayered

[jonas_schneider]

Hello,

I came across something that I quiet dont understand. I want to add scratches to my glas material, I wanted to mix some texture with VRAYLayered but when I render my scene on my GPU, the bump is getting ignored. When I plug in my texture directly into the bump map channel it works as expected. Is this a known issue or something special of VRAY GPU rendering?

Here those 2 results I get. I am running a 3080 with latest drivers, if this would make any difference.

Hello jonas_schneider,

Currently, there are some known issues with the bump texture, rendered on V-Ray GPU as it will render differently compared to V-Ray (CPU). However, the V-Ray Layered texture is supported on V-Ray GPU and I didn't experience any issues with it. Would you mind sharing a test project where the issue is reproducible so I can have a look? Thank you.

I think it resolved itself? I collected my project and wanted to verify that the problem still exists, but for some reason, the bump is now generated as expected. I even could apply a noise as a mask, that didnt worked yesterday. I will dig into it, maybe I can replicate the issue I had yesterday. But for now, it seems to be fixed.
