I've been following this thread very closely and honestly I'm still a bit confused. We have a 2-D character that flips. We have a polygon collider on his sword that flips just fine. The issue we are having right now is using a hinge chain made from 3-D physics attached to this same character. Looks amazing when running to the right, but as soon as we flip to the left everything breaks. Is there a method I can call on the hinge joints or rigid bodies that would keep this from happening? Let me know if you need more detail.
