Mirror, on the Keyframing Tools rollout (page
2–962), mirrors the motion of the biped through
both the X and Y axes of the World co ordinate
system. The entire biped animation, including
all footsteps and keys, is mirrored symmetrically
through an axis that joins the center for the biped
to the world origin. For example, if a biped is
walking from the center of the world grid toward
theuser,themirrorwillchangethemotionsothe
biped is now walking away from the user.

motion you’ve already created. For example, if a
biped wal ks to the left a nd swings its r ight arm,
mirroring the motion results in a motion where
the biped walks to the right and swings its lef t arm.
The mirrored motion replaces the existing motion
for the biped. If you want to keep the existi ng
motion and add the mirrored motion, use Paste
Opposite in the Copy/Paste rollout.
Note: This feature mirrors only those biped tracks
that have at least one key. The position of a keyless
object is not mir rored.
Usi ng Lay er s
Layers allow you to add successive layers of
animation above the original biped animation.
This is a powerful way of making global changes
to your character animation. For example, simply
addalayer,androtatethespineforwardatany
frame, and a run cycle becomes a crouched ru n.
The original biped motion is kept intact, and
can be v iewed by switching back to the orig inal
layer. Layers can be viewed individually, or as a
compositeofalltheanimationinalltheLayers.
Layers behave like a freeform animation (page
