time. The following tracks are influenced in the
vicinity when a footstep is edited in space:
• Body Horizontal keys change to step or hop

Note: If for some reason you do not want the
adaptation to occur, use the Footstep Adapt
Locks settings on the Dynamics & Adaptation
rollout (page 2–980) to keep the biped from
correcting the body position.
Two additional rollouts display when Footstep
mode is active: Footstep Creation rollout (page
2–988) and Footstep Operations rollout (page
2–990).
Footstep Crea tion R ol lout
Select a B iped with footsteps > M otion panel > Biped
rollout > Footstep Mode > Footstep Creation rollout
The Footstep Cr eation rollout, available on the
Motion panel w hen Footstep mode is on, provides
controls for creating and editing footsteps. Create
a walk, run, or jump footstep pattern using these
controls.
Tip: All footsteps created here are inactive; you
activate them using Create Keys for Multiple
Footsteps on the Footstep Operations rollout (page
2–990).
The timing parameters at the bottom of the rollout
work with Create Footsteps (append) and Create
Footsteps (at current frame) to change timing for
newly created footsteps. These change depending
on whether you select Walk, Run, or Jump mode.
