Put some clothes on!
Finally doing it for the poor girl. Look how happy she is now:
Lots of issues like z-fighting, weird bone wrapping, lack of double faces, some abnormal vertices weights.... And well, just plain white clothes!
But on the other hand, you can put any clothes you want (as long as you have the clothes in question, ofc), this will be a feature in the game.
Here are her in some other clothes.
The technique used for this is skin remapping.
Now that she's properly dressed, what about... hair?
Lets get her some hair over this pretty bald spot next!
