If a limb has twists, the twist links will
control the skin deformation while the base link
(the biped’s forearm, for example) drives the
animation. Twist links can not be animated.

available in Footstep mode.
If footsteps are extracted during motion capture

• Body H orizontal k eys change to step or hop
within range of new footstep locations.
• Body Vertical keys change to match possible
changes in stride length, since the body must be

• Right or left leg keys in a move state must be
