Set Key—Creates keys at the current frame
when you are moving biped objects. This is
ident ical to Set Key on the 3ds Max toolbar.
You can exp eriment w ith different biped poses
without updating the motion until you find the
desired pose. You can also quickly fine tune your
motion by sett ing a key and adjusting the key
parameters on the Key Info rollout without having
to transform the biped in the viewports.
Note: If a biped key is current, then TCB, XYZ
position spinners, and IK Blend parameters c an be
updated without using Set Key or having the Auto
Key button turned on.
Note: If3dsMaxbonesusingtheIKControlleror
3ds Max Particle Emitters are linked to the biped,
or if you are displaying 3ds Max trajectories or
ghosting, the Auto Key button must be on while
the biped is positioned. T hese objects update their
parameters in real time as they are positioned.
Delete K ey—Deletes the key of t he selected
object at the current frame.
By default, biped arm, hand, and finger keys are
stored in the clavicle track. If you delete keys for
any one of these objects, you lose positions for
the rest of the arm objects at that frame. If you
plan on extensive hand animation, turn on Arms
intheSeparateTracksgroupoftheKeyframing
Tools rollout. This creates separate tracks for each
biped arm object. Deleting an upper arm key will
preser ve hand and finger keys.
Set Planted K ey—Sets a biped key with IK
Blend=1, Join To Previous IK Key turned on, and
Object selected in the IK group.
In a Footstep or Freefrom animation, all footsteps

dialog, which lets you set new default values for
subsequent TCB keys.
Set Sliding K ey—Sets a biped key with IK
Blend=1, Join To Previous IK Key tur ned off, and
Object selected in the IK group. This creates a
sliding footstep. Sliding footsteps display in the
viewportswithalinerunningthroughthemiddle

footsteps with moving IK constraints.
In a Footstep or Freeform animation, if the foot
slides rather than being planted, use Set Sliding
Key .

dialog, which lets you set new default values for
subsequent TCB keys.
Set Free Key—Sets a biped key with IK
Blend=0, Join To Previous IK Key tur ned off, and
