How about Root Motion from Mixamo animations. I have imported a skeleton to Mixamo, remapped joints so my Root Bone (joint at 0,0 top of joint chain) using their rig mapper. Applied an animation and noticed that my root bone has not only translations applied to it but rotations as well. It seems to be inheriting motion from Hips. Unfortunately, this doesn’t work very well with Root Motion in UE4.
Maybe I am missing something.
