Its brawls material files. Its practically a material file, only having what was included when it was exported. What you would want to edit is the multiple difuse colors. They are usually in different spots because of all the forms of pointers and the extra stuff it would have included. CLR0's are usually more than 1 color (color animation, if each color is used at different points, there will be more pointers at the start, if they are used in a sequence, it will be associated with a PAT0 file). I know little about the sequentail color animations, but from what i saw, thats what i gathered.
Hmm okay, sounds like a though time for me to get something like that done. I searched for a guide on google but with no results... do you know where to find any guide for it?
