Biped Rollout 793
Footsteps Operation rollout. The changes can be
pasted back by turning off Buffer Mode, turning
on Paste Footsteps on the Footstep Operation
rollout, and overlapping the buffered footsteps
w ith the orig inal footsteps. The buffered motion is
spliced into the original animation.
Rubber Band Mode—Use this to reposition
the biped elbows and knees without moving the
biped hands or feet in Figure mode. Reposition
the biped center of mass to simulate the physics of
wind or weight pushing against the biped. Figure
mode must be turned on to enable Rubber Band
Mode.
To reposition biped knees and elbows, turn on
Figure mode and turn on Rubber Band mode.
Select the Move transform tool, then select and
drag a biped upperar m or thigh in t he v iewports.

To reposition the biped center of mass relative to
the rest of the biped skeleton, turn on Figure mode
andturnonRubberBandmode.SelecttheMove
transform tool, then select and drag the center
of mass in the viewports. Use this to account for
wind force or pushing agains t a heavy object. See
Shifting the Biped’s Ba lance (page 2–734)
.
Note: Rubber Band mode behaves differently
than Non-Uniform Scale. For example, if you
"Rubber-Band " the biped thigh, the thigh and
biped calf objects scale propor t ionally to keep the
biped foot stationary. Using Non-Uniform Scale,
the calf retains its s ca le and the foot moves.
Moving the biped center of mass (blue diamond) behind
the character, turns this default walk cycle into a st ru gg le
against a high wind.
ScaleStrideMode—Footstep stride length
and width are scaled to match the stride length
and width of the biped figure. Scale Stride mode is
on by default.

and when you scale the biped’s legs or pelvis.
For example, if you load a .

from a larger biped, the footsteps come into your
