This topic was touched on before but I'm still having problems with it. Somebody asked how to color sticks differently from cartoons and Warren explained that this can be done by creating duplicate objects. I managed to accomplish that, but when I ray-trace the image the cartoon takes the same color as the stick does. As soon as I move the ray-traced image, it restores back to the different colors, as I want them.
For example, I colored the cartoons in one object green, while I showed only sticks in the duplicate object and colored a specific residue stick blue. When I ray-trace the image, the cartoon at that residue turns green, instead of staying blue. Is this a bug or how can I get around this?
