What about coding your script so it replaces colors on certain places on a bitmap to the 3d object (I'm taking this idea from when you do things like add a blood bitmap and directly draw it on the 3d model), basicically I hardcode where the game knows to replace a given color, and then the only dynamic part of it is the color values that are chosen? I'm not sure how clear I'm being, what I mean is there are two ways of adding a bitmap to an object, one is to directly place a sprite on a surface, and another is to take that bitmap and draw it INTO the 3D object's bitmap that you want it to be applied to. But I'm not exactly sure how to do the second way. I think my origional suggestion (drawing on a bitmap through code) has a similar use in one of the AUM's but I'm not sure...

P.S. thanks for responding
