These parameters apply to the biped center of mass and are used by character
studio to calculate the biped’s airborne trajectory based on gravity (GravAccel)
and time between footsteps, the amount of knee bend on landing (Ballistic
Tension) and how the biped objects adapt to maintain balance (Balance Factor).
Balance Factor Position the biped's weight anywhere along a line that extends
from the center of mass to the biped’s head. This center of mass (Body
Horizontal track) parameter can be keyframed. To activate Balance Factor
select the Horizontal Track (in the Track Selection rollout), set a key and enter
a value in the Balance Factor field.
For example, to create a sit then walk sequence, you could shift the biped’s
weight (balance) between 0 (the character is supported by the chair) for the
sit key and 1 for the stand key (the character’s pelvis shifts to maintain
balance).
If a character is seated, and reaches across the table, leave Balance Factor at 0;
however the character leans, he will pivot from the center of mass. The pelvis
will not move back to maintain balance.
In a walking motion, a value of 2 will swing the hips and keep the biped head
steady; a value of 0 will keep the hips steady and swing the upper body.
