Ok so apparently I didn't. There's a lot of stuff I want to fix and before I send out an update, which also includes making the models skinnable.
I need to figure out how to make bipeds movable in max 5.0. I can't move/rotate a single biped anymore. I have the animation/bone mode on, no keys are set.
EDIT: Nvm, got it to work yay.
EDIT: Nvm I didn't. The damn Biped just won't move.
