in a freeform animation. A completely freeform animation contains no
footsteps.
To start an entirely freeform animation, simply create a biped and begin
keyframing.
NOTE Once you initiate a freeform animation, you cannot add footsteps to it in
Footstep mode. You can, however, convert your freeform animation to a footstep
animation using Convert on the Biped rollout.
You will often want a freeform period in a footstep sequence; for a walk then
fall type of motion for example. In cases like this, a freeform period is specified
between footsteps in Track View using the
Footstep Mode dialog on page 4457.
A combination of footsteps and freeform is often required when motion
capture data is imported. A freeform period is created using controls in the
Footstep Mode dialog and display as a yellow boxes between footsteps in Track
View.
Right-click the footstep track to display the Footstep Mode dialog; here you
specify a freeform period, select multiple footstep edges, and set footstep
numbering display options.
Biped Color-coded Keys and Trajectories
Biped uses color coding for IK keys in three places: Track View, Track Bar, and
when trajectories are displayed in the viewports. Also, depending on the types
of keys, trajectories themselves can be color coded. The color coding helps
you visualize when IK and FK are in use, and transitions between them.
This topic describes color coding of non-
COM on page 7933 tracks. For
information about COM key color coding, check
here on page 4353.
Color-coded Keys in Track View and on the Track Bar
Biped IK keys as displayed in Track View and on the track bar use the following
color scheme:
orange for planted keys
yellow for sliding keys
blue for body-space IK keys with a non-zero value for IK Blend
All other keys use the default color: gray.
