I seem to have run into an issue with my animation that I simply can't wrap my head around. My fairly simple run animation looks fine while it plays in the original blender file, but as soon as I export it as fbx and load it back into Blender (or Unity) it appears completely broken.
I suppose it might be something IK realted considering it's the legs that are going berserk, altho I feel like I've double checked every possible option as well as scaling/roll etc., but maybe I'm missing something. -What am I doing wrong?
Obviously broken animation after export
Original animation as it plays in the blender file
