Guys, how do I fix the following problem ...
This box will have an impression on 2 sides so I made a UV mapping texture to the outside, duplicated it and added it to the interior, while using one of the standard Cinema 4d render engines I perfectly see the two interior and exterior textures.
Now comes the problem, when selecting the V-ray as render engine I only see the exterior texture reflecting on the inside.
Even converting the material to V-ray, the problem remains.
Any tips on how to fix this?
