Synty and Mixamo - 5 hours and no solution

I am trying to get some mixamo animations to work with the Sci-Fi city synty pack.

I’ve tried universal animations and mesh2motion too.

I cannot seem to get it to work, hours of YouTube, praying that AI can finally actually solve something, all for naught.

What I have is, I believe atleast, a retargeted animation and synty GeneralSkeleton (made unique), an animation library with a single walk animation, and that’s it.

The head moves a tiny bit, but otherwise the whole character moves as if moving the x/y axis only.

Can someone please help! Thanks!
