with changes to footstep timing, except in cases where 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.

Use Footstep mode to create and edit footsteps. Use Keyframe mode (Footstep

mode off ) to create and edit your character's keys. You can always edit the

timing of both footsteps and keyframes in Track View.

While the biped's feet are airborne, you can animate its legs as you do its upper

body. Biped does not create keys based on physics while the biped is off the

ground, so 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

on page 4227.

You can make 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 parameter lets you store the anchored position and

combine inverse with forward kinematics. After you've set keys, be sure to

remove 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.

NOTE On the time slider or in Track View, you can move one Biped key past

another. See

Moving Keys on page 4466.
