Using IK retargeter in 5.5 to create Root Motion animations?

I know how to do realtime retargeting. That’s what I’m doing already.
–What I want to do is to generate root motion from my animation, that does not already have root motion. I feel like that is almost happening, I just cant quite get it to work

(Also to hide the skeletal mesh instead of using an invisible texture, you can simply unset visible..

and then set Always Tick Pose and Refresh Bones

this means that the skel mesh animates even when hidden.)
