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 become a kind of
gizmo on page 7996 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 activated.
See
Understanding Footstep and Body Keys on page 4196.
Key Adaptation for Footstep Placement Edits
When you move or rotate active footsteps as described in
Editing Footstep
Placement
on page 4199, the biped's keys are immediately influenced by the
edit. The following keyframe tracks are influenced in the vicinity of the edited
footsteps:
■ 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 center of mass must move lower to step longer distances
■ Body Turning (Body Rotation) keys change to bank into turns created by
changes in path curvature or body speed
