Aye, thanks for viewing! Quest, null-reflections come from rendering with a Ray Depth that is too low for the object being rendered. Of course, Ray Depth has no effect on materials/objects that are not transparent or reflective. If you had a white background/sky shpere, you would still see black nulls. I believe the null-colors are based off of the Master shadow color, in the Sky pallete. One more render should clear all of that up, back in a few...
