Double Faces Vray5 vs Vray Next

[stefan_haehnlein1]

Hello,

I have a scene with CAD-data I rendered some time ago with max 2020 and VrayNext. Rendering the same animation sequence now with max 2022 and most recent VRay5 version I have some flickering of double faces in beauty element. Because it is behind a glass surface it is also in refraction render element. The flickering was not there in max 2020/Vray Next. I have already set the secondary ray bias to 0.001 without improvement. Is there something else I can do or some explanation why whis issue is not in the order VRay Next version?

regards,
Stefan

you can try increasing the ray bias even farther, but ultimately it would be best to fix the coplanar faces.
