The foot doesn't touch the ground in Retargeting

I’m trying to retarget the animation MF_Unarmed_Idle_Ready from the mannequin of Lyra to Shinbi, but she remains floating. If I adjust the local offset of the root setting in the retarget asset, this causes problems with the FK solver. Any ideas on how to solve this problem?

If I recall…the invisible mesh in the character needed to be lowered like 5 units or so. Because the mannequin wasn’t actually lowered all the way to the ground by default… IK made it seem as though it was. I don’t think any retargeter adjustment was necessary.

But I’m using the same control rig as the mannequin, shouldn’t it resolve it too?
