except in cases w here default leg keys must be

regenerated to account for timing edits that alter

the basic gait pattern, such as creating a hop in the

middle of a walk.

in Track View.

While the biped’s feet are airborne, you can

animate its legs as you do its upper bo dy. Biped

does not create keys b ased on physics while the

biped is off the ground, s o animating the legs

might be necessary to make long leaps realistic.

Alternatively, you might want to make the biped

appear to be floating in midair, or underwater, or

have it ride a bicycle. See Freeform Editing Between

Footsteps (page 2–883).

You can ma ke the biped interact with other objects

in the scene: throwing or kicking a ball, opening a

door, and so on. You do this by attaching a biped

limb to an object in the scene.

An animatable IK Blend par ameter lets you store

the anchored position and combine inverse with

forward kinematics. After you’ve set keys, be sure

to remov e the anchors.

Tip: You can often get good results by loading an

existing biped motion and then varying it. You’ll

find a set of sample motion files on the program

disc in the \Samples\Motions directory.

move one Biped key past another. See Moving Keys

(page 2–1004).
