Footsteps Operation rollout. The changes can be
pasted back by turn ing off Buffer Mode, turning
on Paste Footsteps on the Footstep Operation
rollout, and overlapping the buffered footsteps
w ith the original footsteps. T he buffered mot ion 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 B and
Mode.
To reposition biped knees and elbows, tu rn on
Figure mode and t urn on Rubber Band mode.
Select the Move transform tool, then select and
drag a biped upperarm or thigh in t he v iewports.

To reposition the biped center of mass relative to
the rest of the biped skeleton, tu rn on Figure mode
andturnonRubberBandmode.SelecttheMove
transform tool, then selec t and drag the center
of mass in the viewports. Use this to account for
wind force or pushing against a heavy object. See
Shifting the Biped’s Balance (page 2–876).
Note: Rubber Band mode behaves differently
than Non-Uniform Scale. For example, if you
"Rubber-Band " t he biped thigh, the thigh and
biped calf objects scale proportionally to keep the
biped foot sta tionary. Using Non-Uniform Scale,
the c alf retains its scale and the foot moves.
Moving the biped center of mass (blue diamond) behind the
character, turns this default walk cycle into a struggle against
ahighwind.
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.

ScaleStridemodeisonbydefault,soscaling
occurs automatically when you load a .bip,.stp,or
.fig file. Scaling occurs when you paste footsteps
and w hen you scale the biped’s legs or pelvis.
For example, if you load a .bip file that was saved
from a larger biped, the footsteps come into your
current scene sc aled to match the selected smaller
biped.IfScaleStridemodeisoff,thefootsteps
