If you want a character's big toes to have thumb-like movement, map the toe bones to the “LeftFootThumb” and “RightFootThumb” slots of the Mapping List. You might want this behavior if, for example, you have a quadruped with opposable thumbs on their feet, you should use the thumb. You can also use the thumb for dew claws.
If you want the character's big toes to have normal toe movement, map the toe bones to the “LeftFootExtraFinger” and “RightFootExtraFinger” slots in the Mapping List.
If your character model has bones named using naming conventions from previous versions of MotionBuilder, the toe bones are named “LeftFootThumb,” “RightFootThumb” and so on. When you map and characterize this model, the toes use thumb-like behavior unless you rename them or manually map them to the “LeftFootExtraFinger” or “RightFootExtraFinger” slots.
