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 Design, with a few restrictions.
Before reading this section,
Footstep and Body Keys for terms and definitions
used in this section.
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
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
All options available
for editing biped body key timing are available only when Edit Keys
on the Track View toolbar is turned on.
The following rules apply
to the editing biped body key timing in Track View:
- You cannot move existing keys outside
the area between the first and last footsteps, or to negative frames.
- You can use Add Keys to add keys to
any biped body track. You cannot add keys outside the area between
the first and last footsteps, or to negative frames.
- You can clone keys the same way you clone 3ds Max Design object
keys, by selecting keys and holding down Shift as
you drag them. You can also clone keys by copying and pasting postures.
Copying and Pasting Postures and Poses.
- The Track View – Curve Editor can be
used to view and edit curves showing the interpolation between body
keys. You can also use the Workbench to analyze, edit and fix biped
motion curves. See
with the Workbench.
- You can use Scale Keys to scale selected
keys, except for locked keys.
TipIf you want to animate
a biped performing movements with its upper body while standing,
extend the length of the standing footsteps to cover the length
of the standing animation, then add keys for the upper body.
