When Footstep mode is active, you can create or edit footsteps to generate a walk, run, and jump footstep pattern. You also edit selected footsteps in space and append footsteps using parameters available in Footstep mode.

(Footstep Mode)
If footsteps are extracted during motion capture import, turn on Footstep mode to edit footsteps in the viewports.
A powerful feature in Biped is the ability to adapt keyframes when footsteps are edited in space or time. The following tracks are influenced in the vicinity when a footstep is edited in space:
- Body Horizontal keys change to step or hop within range of new footstep locations.
- Body Vertical keys change to match possible changes in stride length, since the body must be lower in order to step longer distances.
- Body Rotation keys change to bank into turns created by changes in path curvature or body speed.
- Right or left leg keys in a move state must be adapted to step between new locations. Note: If for some reason you do not want the adaptation to occur, use the Footstep Adapt Locks settings on the Dynamics & Adaptation rollout to keep the biped from correcting the body position.
Two additional rollouts display when Footstep mode is active: Footstep Creation rollout and Footstep Operations rollout.
