David, Oops! I played with this one and it looks like what happens is that with atmosphere turned on (fog or Distance cue) the box IS reflected in the sphere, but the renderer is ignoring the object material and is making it the same color as the fog color. I did this: – Create an L-sphere and a box in front. Create camera and omni light. Assign blue plastic to the box and a pure auto reflect material to the sphere. Should render fine. – Set up camera ranges so both objects are inside ranges (to keep object colors clean). setup a yellow fog and turn it on but leave the fog background button off. When rendered I got a black sphere reflecting a pure yellow box (even though the box is blue.) Go back and turn on the fog background and when rendered all you should see is a mirrored ball reflecting a yellow box against a yellow background, in other words, a solid yellow screen! I think this is the same for distance cueing only your seeing the box reflection blend into the black background. I only played with fog, but tried different materials and settings, all with the same effect. Sounds like a creepy crawly to me. A big hairy mean one! <g> David
