The way the playermodel works is by having every single item/acessory modeled onto the player.
All the game does is hide and unhide the nodes of every hat, armor, or whatever.
so more default stuff or choices means baddy would have to re-export the model.
Again.
Also, the way around this is by attaching models to the nodes on the body, cept you can only have 4 on at a time.
That includes all armor and weapons.
I.E.
the idea of baddy doing this isn't likely.
It would have to be user-made.
