Requires some work when importing into Unity. When switching rig animation type to humanoid, instant errors. Under Avatar Definition, selected Create from this model, then Configure. Scroll all the way down, select Mapping > Clear, then Mapping > Automap. Gets you 90% of the way there. Had to fix leg bones. Chest and upper chest empty (optional bones anyway). Head and hands automap well - can optionally manually map Thumb Distal.
Previewed some animations on the male model after that and they looked okay.
