ive been searching for a tutorial on how to do this in blender 2.49-2.6

i have a car model that i want to use a color shifting paint on but so far no luck

was also thinking that for things like mother of pearl, pearls, gems, and whatever else it would be a good thing to try

any help wil be much appreciated

 

and tuts on direct export from blender to poser or studio would be great too
