Hello,
So I am making a game character that will have replaceable limbs.You shoot it in the arm with shotgun,arm explodes and it’s replaced with another mesh ( just arm) with bones showing,skin,blood and everything 
I have a character that is cut in pieces (all replaceable parts),he is rigged and skinned and it all works fine.
But I want to transfer skin weights to a character with ‘destroyed’ limbs which don’t have the same number of vertices.
I tried selecting for example an arm and binding it to the rest of the body which was already skinned and everything looks fine but there is a small gap between arm and the body ( when it’s animated)
So I just deleted history,selected arm and the body and smooth binded.There is no gap but weights are messed up on the body.
Is there a way to transfer weight to a character with different mesh ?
thank’s
and sorry for my english,I did my best
