I don’t know if it’s something about my rig or my fbx export options or something else, but the legs after the export goes crazy, I tested it, it only does that if my hip controller is rotated in extreme poses (but I could be wrong). Don’t know if anyone can help me, but thanks in advance for everyone.
PS: I worked in the 2.8 beta version of Blender, I had to switch from 2.79b because of some other reasons, and I am pretty sure 2.79b cannot open the file.
