Editing Active Footsteps
One of the most powerful features of footsteps
is the ability to adapt keyframes automatically
to edits you make to your footstep pattern. By
analogy, the footsteps b e come a kind of gizmo
(page 3–949) for manipulating the keyframes of
your character’s animation. In most cases, edits
you make to footsteps act upon your keys in an
intuitive fashion.
In order to understand what happens when active
footsteps are edited, you must first understand
what happens to biped keys when footsteps are
activat ed. See Understanding Footstep and Body
Keys (page 2–867).
