Actually, as far as your plan to modify the reflection channel of the shader, well, that would be odd. What I think would work better for you is to put an image of your setting in the background of your Carrara project. You can put a solid color (black or a chroma-key color, depending on how you're planning on removing the trophy from the BG) in the backDROP. The metal texture of the trophy will reflect all the stuff in the background, giving you that interactive, interesting light look. One of the two parents of Carrara, Infini-D had exactly such a feature designed for chrome work. It was a t-map that was put in Infini-D's equivalent to the background that looked like strange noodles, but it reflected in the chrome surfaces and looked great. HTH. - Dex
