Layers allow you to easily adjust raw motion
capture data containing keys at every f rame.
Simplyaddalayer,andkeyframethebiped.You
can also use layers to change the g loba l position of
the biped in a freeform or footsteps animation by
adding a layer and moving the center of mass.
Pr ocedur es
To increment all k eys using layers (global offset):
1.
On the Motion panel Layers rollout, click
Create Layer to create a new layer. Enter a name
for the layer in the Layer name field.
2. Create an offset (or "increment") by setting one
key. You can either use Auto Key mo de, or click
Set key on the Key Info rollout (page 2–954)
(this c an be done at any frame.)
3. Click Collapse to collapse the lay er.
To increment a n interva l of k ey s wi th a n envelope
(blended of fs et):
1.
Create a new named layer.
2. Create an offset by setting one key. You can
useeitherAutoKeymode,orclickSetKeyon
theKeyInforolloutattheframewherethe
increment is to occur.
3. To create the envelope, use Snap Set Key
to create keys before and after the incremented
range.
4. Click Collapse to collapse the lay er.
To increment a n inter v al of k ey s wit hout an envelope
(nonblended off set):
1.
Create a new named layer.
2. Create an offset by setting two keys. You can
useeitherAutoKeymode,orclickSetKeyon
the Key Info rollout. Set one key before the
frame w here the increment starts, and another
after the frame where the increment ends.
3. Use Snap Set Key to create keys before
and after the incremented range to clamp the
motion to the offset only occurs in the range
between t he two keys.
4. Click Collapse to collapse the layer.

Editing Tr ajector y K eys
By turning on biped trajectories, selecting the
center-of-mass tr ack, and turning on Sub-Object:
Trajectories, you can select a key on the trajectory.
Then either use Bend Horizontal in the Keyframing
Tools rollout (page 2–962) to bend the trajectory
about the selected key, or simply move the key.
You can move center of mass trajectory keys either
horizontally or vertically. This allows you to view
theentiretrajectoryofthecenterofmassandbend
or edit the trajectory.
Tip: You c an select the center of mass’s horizontal
or vertical tracks by clicking the appropriate
button in the Track S election rollout (page 2–945).
