3D Clothing Skinning

Howdy. Does anyone know the root cause of this clipping? Do I not have enough geometry on the vest model? Or does it have something to do with the cage setup?

Hi. I know this is a late response, but it looks like the vest only has a crease at the hip (which allows it to bend). The vest seems otherwise stiff and doesn’t look like it has any creases on the torso, even though the rigs torso seems to move. If your vest is stiff on the torso but the torso moves, you might encounter clipping. The other possible problem could be that the vest moves to the side with the arms even though the torso doesn’t move as much, which might cause the torso to collide with the vest. There’s a lot of possibilities but I hope this helps you.
