hello , I have a problem with slicing skinnedmesh , what happens is that one of the objects (neg/pos) starts to act very jittery and flies into the air. I cant find the problem but it seems that the hierarchy of bones and joints is not correct. it usually happens when I slice the character's legs but not always.
I share a screenshot here
