Charles (or do you prefer Blaq?), A few questions about your suggestion on how to de-focus reflections. Would your technique slow rendering down, the more blurry the reflections are set? If so then I'd be in a favor of something simpler, if there is anything simpler. Would it require more rays to be traced, or would it simple resample the existing rays? Would it blur other properties of the object, such as Color or Reflectivity (not Reflection) Brushes? If so this would ruin the effect we're trying to achieve? The idea is to illuminate the detail in shaded areas. This already works quite well when using a combination of a Reflectivity brush and global maps. The Reflectivity Brush nicely controls the tint of the light bouncing back, heightening the detail in shaded areas There may be no way to *totally* eliminate the sharper appearance of reflections on a tightly curved surface. I may have over-emphasized this problem. The global mapping technique actually works pretty well except for the other problems I mentioned: sharp reflections from other objects, or no true shadows in Scanline without some work-arounds. -@-@- > Tim
