So I decided I wanted to make a Mario skin that makes his head 3x as big, makes the rest of his body invisible, and translates his head down so the bottom of his chin is approximately where the bottom of his feet are.

I went into Mario's MotionEtc file and edited the HeadN bone to a scale factor of (3,3,3) and changed bones LShoulderN, RShoulderN, LLegJ, and RLegJ to a scale factor of (0,0,0) for the idle animation(wait1, wait2, wait3).

I also went into Mario's individual costume slots and changed the HeadN bone in those files to be translated down. This was the only way I managed to get the translation part to work.

Resizing Mario's body parts results in a graphical glitch as shown below No matter how I change the camera that "part" of Mario always covers that part of the screen like that. It doesn't seem to happen on every stage, but it does on a lot of them. It goes away when Mario's other animations play.

Basically, what I'm trying to do is have each individual costume have a different final smash. I heard this was possible with Brawlex.

For example, have Wario's blue costume use a blue Wario Man skin, while the rest all use regular Wario Man.
