Layers allow you to easily adjust raw motion
capture data containing keys at every frame.
Simplyaddalayer,andkeyframethebiped.You
can also use layers to change the global 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 mode, or click
Set key on the
Key Info rollout (page 2–809)
(this can be done at any f rame.)
3. Click Collapse to collapse the layer.
To increment a n interva l of k ey s with 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 e nvelope, use Snap Set Key
to create keys before and after the incremented
range.
4. Click Collapse to collapse the layer.
To increment an i nter va l of keys without an envelope
(nonblended off set):
1.
Create a new named layer.
2. Create an offset by sett ing 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 the two keys.
4. Click Collapse to collapse the layer.

Editing Tra jector y K eys
By turning on biped trajectories, selecting
the center-of -mass track, and turning on
Sub-Object: Trajectories, you can select a key on
the t rajectory. Then either use Bend Horizontal
in the
Keyframing Tools rollout (page 2–816)
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 the entire trajectory of the
centerofmassandbendoreditthetrajectory.
Tip: You can select the center of mass’s horizontal
or vertical tracks by clicking the appropriate
button in the
Tr ack Selection rollout (page 2–800)
