To create a biped with knees that bend backwards, rotate the biped calves
or thighs of both legs 180 degrees about their local X-axis (along the length
of the limb). When you exit Figure mode, the biped walks, runs, and jumps
with reversed knees.
When working with a mesh in a symmetrical pose, pose one side of the
skeleton, and use controls on the
Copy/Paste rollout on page 4389 to paste
the posture to the opposite side of the biped.
