Ok, im having an issue with weight painting a shirt onto a body where the shoulder bones/biceps are rotated to compensate for IK bones that have pole targets at -180 degrees. The model is rigged this way and I cant change it at this point.
My issue is after modeling a shirt, it looks fine not weight painted.
Then when I parent with automatic weight, the shoulder paints (which is what I actually need) make the mesh move inward
Is there a solution that doesnt involve making a WHOLE new armature? What can I do here?
