A Balance Factor value of 0 in the first image causes the biped not to compensate for
weight.
A Balance Factor value of 2 in the second image causes the biped pelvis to move away
from the Center of Mass to compensate for weight.
The Balance Factor determines how far the biped's hips will shift forward or
backward to compensate for forward or backward bending of the spine. When
the biped has a normal weight distribution between the upper and lower body,
the default value of 1 causes the hips to swing backward as the biped bends
over to compensate for the forward weight.
At times, when the biped leans, you will want the biped's hips to refrain from
shifting to compensate for the forward weight. This would be when the biped
is sitting or falling down. A Balance Factor of 0 (the minimum value) causes
the hips to stay still when the biped leans forward or backward.
A value of 0 places the biped’s weight at the center of mass. A value of 1 places
the biped’s weight above the center of mass. A value of 2 places the biped’s
weight in the head. Click the spinner up arrow to move the biped’s weight
distribution toward the head. Range=0.0 to 2.0; Default=1.
NOTE You can also shift the center of mass by turning on Figure mode, selecting
the center of mass object, and using
Rubber Band mode on page 4331 to move the
center of mass to a new position. This method cannot be keyframed, but it allows
you to move the center of mass outside the biped body. For example, you can
simulate pushing a heavy object by moving the center of mass behind the biped.
