    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.

    Can you just not flip the 3D chain? Turn it around 180 degrees and re-attach it instead? Flipping doesn't really make a lot of sense in 3D.

    We are using Spine for our animations and basically one of our characters has a light on a strap that bounces around via physics chain. The images themselves are dependent on the chain. Basically this chain is added as children of the graphic part of the character. I initially did have the light separated and that solution you mentioned did work previously, but no dice this time around :/

    Have you tried double-flipping them? So, flip the parent, then flip the children to unflip them.

    The alternative, I'm afraid, is to re-build the chain each time you flip. Scale flips just do not play nice with joint anchors.

    It's been 2018 and again this problem is relevant.
