Finally!
Added 2021-06-08 22:07:21 +0000 UTCI have been stuck for four days trying to fix a problem in Raina's rig. It was acting weird in a way I'd never seen before. I finally realized it was a new feature added in 2020 that must have turned on without realizing it; Limited bones. Once I turned it off, everything snapped back the way it should be (facepalm).
Anyway aside from the limited bones issue, I transferred all of the mocap data to Raina's rig and I've been doing a lot of clean-up. All leg/foot animation was done by hand using the mocap as a reference. Clavicles were also animated by hand for extra emphasis. More clean-up is needed for her arms/hands.
I have to repair some of the weightmaps I messed up while trying to figure out the rig problem. Then back to more clean-up. More to come.
