IR map that has a very bright wall...can u help me?

[bover]

Hey all,

 

I'm working on a new IR map and what I'm seeing is a map that looks good,however, one wall is really bright. All objects have the same material applied to it,but, this one wall seems really bright over the others. I've attached a JPEG of my issue. Take note of the sun-light source. It's almost directly above the scene.

 

My generic matl: is Finishes Ceiling paint I belive that this is a flat (reflective) material.

 

Is anyone seen this before or can anyone help me with my issue?

 

I'm using Max 7 with V-ray 1.47.03....
