The Script Extension (TSE) package comes with a script the changes the color of an object based on its position relative to some other objects. The same general idea could be implemented with TSE to do what you want. LAM

>>angled faces reflecting colors relative to the light… Andrew, While not specifically relative to a light source, you can easily change the face colors relative to the environment. I did this in about 3 minutes using a radial spectrum gradient (using the KPT gradient designer IPAS). Getting the right colors is a matter of creating an apppropriate gradient. – Create or load a spectrum gradient (I used the Cosmic Spectrum supplied with KPT). Set circluar sunburst, pinch left. Save the .GRD file and apply it as a reflection map, 100%; set specular=white. – Create objects with flat shading and apply the reflective material. As they are rotated, each face "reflects" a different portion of the reflection map based on its angle to the environment. – To change the specific colors reflected for specific angles, you can adjust the gradient bitmap, or, – To fine tune the effect (or adjust the angle relative to a "light", if I understand what you want), simply link the everything, including camera and target, to a dummy and rotate the dummy. This in effect rotates the reflection map relative to the environment. For more precise control if you don't have too many faces to deal with, you might be able to use mirror reflections with an appropriate spectrum applied to an object off-camera. JKJ
