Reflection Problems

[bjoern_degroote]

Hello, i have sudden issue rendering a scene. I do a lot rendering without any issues but in this case there is a lot of grain? in the reflection. This scene is very big about 3 Gb, maybe thats a problem? Others are about 0.5 - 1 Gb.
The same issues in CPU rendering.

System Windows 10, I9 Gen 10, 64 Gb Memory, 3DS Max 2023, Vray 6 2.1, GPU RTX 5000

Hi, thanks for posting. The resolution of your screen grab is very low but this looks like VRayDenoiser artefacts Are you using denoiser in your scene? Please try to reset your render settings to default and test again.
