Footstep Mode Dialog 1001
Inter face
Edit Footsteps—In this mode (which is the default),
you c an edit the biped’s footsteps to change their
duration; start and end frames; airborne duration;
and s o on.
Edit Free Form (no physics)—In this mode, you can
edit the biped’s body keys for the frames at which
the biped is airborne.
Free Form suspends the physically based dynamics
that normally control biped motion. This is
essential when you want to make the biped fly,
or sit down, or fall over . Note that the freeform
period must be between footsteps.
The freeform area appears as a yellow block between the
footsteps.

frames.

contact with the ground.
You can also turn on the following two numbers
