Vray 3.4 for Rhino - Black circles issues in render

Rhino Rhino for Windows
1

I’m using Vray 3.4 for Rhino and recently I’ve been facing an issue with renders.

Black circles appears on different surfaces (Wall, Glass, Wood, Metal) please note that I have no overlapping geometries and I use the same settings for the past 3 months and never faced something like this.

I would appreciate a prompt response that guides me to a solution.

Thank you

I think it might be a vray bug…does changing slightly camera angle solves the issue? Also you can try force back face culling in vray settings.

Also update to V-Ray 3.6 in case Lukasz is right and the bug has already been solved.

You might want to try revert to default settings.

Can you show us a screenshot of your problem?

Cheers,
