Cr e at e Laye r—Creates a layer, and the Le vel
field increments.
Position the biped to create keys in a layer.
Delete Layer —Deletes the cur rent layer.
All layer numbers ‘abov e’ the one deleted are
decremented by one.
Collapse Layers—Collapsesallthelayersinto
layer 0.
Legs that st ray from the or iginal footsteps in higher
layers are "pulled in" to the original footsteps.
Snap Set Key—Snaps the selected biped part
to its original position in layer 0 and creates a key.
Use this in higher layers to return the selected
biped part to the original motion. If a layer has a
posture key that bends the character for ward at
frame 2 and you want to return the biped to its
original posture motion at frame 50, use Snap Set
Key at frame 50 with a spine object selected. The
character w i l l interpolate f rom its forward posture
position to its original posture position between
frame 2 and 50.
Activate Only Me—View the animation in the
selected layer.
Choose Play after turning on A ctivate Only Me to
view a layer’s keys in motion.
Activate All—Act ivates all t he layers.
Playing the animation shows a composite of all
the layers.
Visible Before—Sets the number of preceding
layers to display as stick figures.
Visible After—Sets the number of succeeding layers
to display as stick figures.
K ey Highlight—Displays keys by highli ghting the
stick figures.
Retargeting Group
The tools in this group let you animate a biped
across layers while maintaining the IK constraints
of the base layer. You can also choose to use a
different biped in your scene to use as reference for
your biped’s retargeted hands and feet.
Biped’s Base Layer—Choose this method to use the
IKconstraintsfromtheselectedbiped’soriginal
layer as retarget reference. Default=active.
Reference Biped—Choose this method to use the
biped whose name is displaye d next to the Select
Reference Biped button as retarget reference.
Select R eference B iped—Lets you choose a
biped to use as retarget reference for the selected
biped. The chosen biped’s name is displayed next
to the button.
Retarget Left Arm—When on, the IK
constraints of the base layer are honored for the
biped’s left arm.
Retarget Right Arm—When on, the IK
constraints of the base layer are honored for the
biped’s right arm.
R etar get Left Leg—When on, the IK
constraints of the base layer are honored for the
biped’s left leg.
Ret ar get R i ght Leg—When on, the IK
constraints of the base layer are honored for the
biped’s right leg.
Update—Calculates the selected biped’s hands
and feet positions for every set key based on the
retarget method (Base Layer or Reference Biped),
the active retarget body parts buttons, and the IK
Only option.
