Glowing white patches??
 

Hi.

I am trying to render an interior scene in mental ray, using GI & FG. I have a single directional light source coming from outside. The problem I am experiencing is glowing white patches in corners, or where bits of geometry intersect eachother. I have not got any textures in the scene yet but i'm a bit mistified as to the cause of the problem, or what I can do to rectify it.

Any help would be very much appreciated.
