inside the yellow box for the airborne period
for which yo u want to suspend gravity. This
fills the yellow box, indicating that vert ical

7. Play the animation. The biped uses vertical
dynamics during all footstep motions except
the freeform period.
No vertical dynamics during freeform period, then

Note: If you activate footsteps after a freeform
period has been set between footsteps, the
biped m ight skip footsteps at one end of the

To edit footstep timing after creating a freeform
period, you must choose the Edit Footsteps
