Root Motion not carrying over in retargeted animation

  1. I’ve been trying to retarget some mixamo animations to the ue5 manny skeleton and it goes fine for the most part, except that I cannot enable root motion in the retargeted animation. The cause for that is that the motion seems to be baked into the bones of the retargeted animation rather than the root. Mixamo’s root moves with the animation (which would allow for it to be extracted with root motion enabled), but UE’s stays in place. Any ideas how to resolve this?

I’ve also tried using the root as the retarget root and retargeting pevlis to Mixamo Hips, but that works worse - the UE mannequin starts hovering in air with the hips fixed in place. In either arrangement, UE manny’s root isn’t moving at all, so root motion extraction wouldn’t work.
