it is even possible replace a model with sprites? i have in mind something but i need to know if this is possible and how D:
you could just set the Z scale to 0 and it would make them flat like a sprite.
oh, what if we take a sprite based item, then add all the bones required for a player character.. this would allow the game to use the sprite model in battle. and you could just replace the sprite image to whatever.
a flattened model and a sprite are two totally different things
