The Track Selection rollout give you specialized
tools for manipulating the biped
center of mass
(COM) (page 2–788)
.Thebiped’scenterofmass
object is the root of the biped hierarchy, and
controls the entire biped structure. Changing its
position and orientation affects the biped as a
whole, which is an impor tant part of posing and
animating the biped.

•Ifthe
viewport rendering method (page 3–896)
is set to Wireframe, you can select the COM in
your viewport, located near the center of the
biped’s pelvis.

Biped rollout (page 2–791)
, which enlarges the
COM in your v iewport. This is useful if the
viewport rendering method is set to Smooth,
and the biped’s pelvis covers the center of mass.
• Youcanopenthe
Select Objects dialog (page
1–78)
, which displays all v isible objects in your
scene. The first listed biped item (
Bip01
,for
example) usually refers to the root; you can
select it from there.
• You have access to three tools on the Track
Selection rollout (on the Motion panel) to edit
the COM’s position and orientation: Body
Horizontal, Body Vertical, and Body Rotation.
Choosing one automatically selects the center
of mass.
Once the biped’s center of mass is selected, you
canmoveorrotateitusingthe
Transfor m g iz mo
(page 3–1119)
. Controlling the COM using
the Track Selection rollou t tools is sometimes
quicker because selecting the center of mass in
your v iew por ts can be difficult if your biped
resides inside a bigger rigged model. As long
as you select your biped by any limb, activating
the COM tools from the Track Selection rollout
automatically selects the center of mass with t he
proper Transform gizmo:

Move gizmo.
• BodyRotationenablestheRotategizmo.
When you key the COM’s position or orientation
using
Set Key (page 3–761)
or
Auto Key (page

, the animation data is stored within the
respective biped transform tracks.
