Just FYI, 

I tried everything suggested here. Adjusted ambient, specular, reflection, and diffuse to a variety of values (including making sure those values only total to 1). I even set all of those to white, instead of black, and played with various combinations of strengths again. I then turned ambient, specular, and diffuse to ZERO, so there was only the reflect node active. Also tried rendering with normals forward. Ran all tests with just simple render settings, then tried them all again with maximum quality (Raytrace, IDL, GC on, etc)

None of that made any difference. All of the Renders turned out exactly as above.

This time all tests were run in a simple room with three walls, Andy 2, and the belt in the scene.

It made absolutely no difference.
