I've started work on a project recently (Although I may not be able to go through with it due to some strange FPS issues), and to make it look as good as possible, I'll need to repaint a character to look entirely different (The same kind of effect as videos such as this http://www.youtube.com/watch?v=09cyrQu5yVA)? My question is how do I do that? if it involves completely redrawing the character, I'm totally screwed, so I'm hoping it works differently to that.
If it helps, I need the change the clothing a character is wearing. Thanks in advance.
