This ability to preserve interdependent relationships allows you easily to
experiment and improvise with motion, since you are assured that edits to
one body part will not corrupt the integrity of other parts.
In general, changes to the center of mass, spine, and pelvis cause the legs to
adjust. Changes to the legs do not affect the center of mass's vertical position.
Adjusting Body Keys in Track View
When you activate footsteps, keys are created for biped body parts. After
activating footsteps, you can also create keys by turning on Auto Key and
animating body parts. All these keys can be viewed in Track View – Dope Sheet
mode.
In general, editing biped body keys in Track View is the same as editing keys
of any sort in 3ds Max, with a few restrictions.
Before reading this section, please read
Understanding Footstep and Body Keys
on page 4196 for terms and definitions used in this section.
NOTE The information in this section applies only to biped body keys for the arms,
legs, spine, neck, and other parts of the upper body. For rules for editing footstep
keys, see
Editing Footstep Timing on page 4200.
Locked Keys
Some biped keys are locked, meaning they cannot be moved in time. Locked
keys are colored red in Track View.
Locked keys for the COM Body Vertical track are created at each footstep's lift
and touch frames. These are the only keys that are locked. These keys can be
moved in time by changing footstep duration in Track View.
Although you cannot move or delete a locked key in Track View, you can
sometimes change the animation on the frame by going to the frame, turning
on Auto Key and manually animating the key.
Restrictions on Biped Body Key Editing
All options available for editing biped body key timing are available only when
Edit Keys on the Track View toolbar is turned on.
