Sketchup 2022 + Vray 5 - white marks

Hey everyone! I am quite new to vray 5 and I am not what the issue is. When I render my perspective these white marks appear on top of the trees.
I have tried different HDRI backgrounds and got the same issue. Does anyone know what the problem? Thanks.

Probably not a bug. Most likely it’s reversed faces in the model.

I’ve already tried to reverse all the faces and still appearing the white marks :frowning:
