use a composite material in 3ds max. Then leave the first layer as teamcolored activeted skin then the next layer as your skin with full alpha channel filtering on. Also you should mark your teamcolor skin as unshaded.
yeah that is what i have configured, and my Teamcolor works ingame! but i cant change the Teamcolor Preview with [ or ]. thtas what i dint understand, my Problem is that i am German, and i dont understand everything in the dokumentation, but i tested those keys before and they didnt work, so i thought i did something wrong!
