Have I a problem with the light or with the materials?

[verdemilonga]

Hi there,
i'm rendering this scene with vray rhino, as you see there's some problem in it.
The walls are looking so bad and they appear affected from something.
I'm using a clear glass for the windows and a simple grey material with noise bump for the walls.

Where is the problem? someone could help me?

Hi,

What kind of lights did you have in that scene?

It seems to me that you have lights you don't need!!!

Show your visopt settings! And one image of your wireframe scene.
