Hello, I'm still fighting with breaking meshes.
I noticed something curious that's definetly not due to some mistake of mine.
I have file #1 in which a certain mesh appears wrong on a specific animation. I take a backup copy of said file in which the mesh in that specific animation looks correct, import skeleton and drag the mesh into skeleton #1 and replace the breaking one. I opened file #1 and #2 side by side, these meshes look exactly the same in setup. Same vertices, same weights, same everything.
In file #1 though, if I go back to the animation, the mesh is deformed differently than file #2
It's the exact same mesh in the exact same pose. I even imported the animation from file #2. Compare them side by side: correct in #2, twisted in #1
