Thanks Psyk0Sith! It was perfect. I read the read-me, and one of the errors fixed was exactly the same which 3ds max gave me.
By the way, now I have the tool, but I do not have the knowledge needed for wat i'd like to do. Forgive me if I break any rule, but I wish you could give me one "step-by-step" guide on how to add a cape from one model to the another.. Those tutorial I read didn't give me the "enlightment" that I was looking for, so.. you are my only hope? xD
Thanks in advance
