Hi everyone i am just a new member here,i am using mental ray3.5 integrated with 3d max2008,and i have a big problem with the exterior scenes with this sitting using(day light,mr physical sky,No AO materials,mr exposure control)

in a scene i just created a building has vertical thin boxes when i begin the animation i found that the faces of the boxes is changing from frame to the other between dark and light and in some frames it looks that it is disappear

Its easier to help you if we can see an image. Sounds like co-planar faces.

co-planar faces means t2 peices of geometry in the same place.
