of moving selected footsteps or selected edges in
time.
Moving an entire footstep changes the time at
which it starts and ends, but not its duration.
Moving a footstep edge changes the duration of
the footstep.
Restr ictions on Footstep Time Editing
The timing for both active and inactive footsteps
can be changed. Editing timing for active footsteps
also changes keys for the center of mass and leg
keys, but not t he spine, arm or tail keys. This can
cause the resulting animation to look different
from the way you intended. For this reason, you
might prefer to deactivate footsteps before editing
timing. See
Deactivating Footsteps (page 2–723) .
When editing footstep t iming in Track View, the
following limitations apply to both inactive and
active footsteps:
• There must be at least one frame between
footstep keys for the same foot.
• Footstep keys cannot star t in negative frames.
• Every footstep must b e at least two frames long.
• If you want to add footstep keys, use the tools
on the Footstep C reation rollout. See
Creat ing
Footsteps Autom atically (page 2–720)
and
Creating Footsteps Manually (page 2–720) .
