The Motion Mixer allows you to mix motion files
(
.bip and .xaf files) for any biped or non-biped
objects. These motion files are also called
clips .

mixer. Motion clips can be cross-faded, stretched,
layered, and finally, mixed down to a single clip.
The Motion Mixer works by placing motion files
on
tracks (page 3–1117) .WiththeMotionMixer,
you can:
• Transition or fade b etween motions.
•Movemotionsintime.
• Trim a motion so only part of it is used.
• Vary the speed of a motion over time.
• Use animation from selected biped or
non-biped body parts within a motion clip.
• Keep planted feet from sliding during
foot-based t r ansitions.

to the biped in the scene, you must turn on Mixer
Mode from the
Biped rollout (page 2–791) .
In the Motion Mixer, motions are imported
and mixed for any objects in the scene. Once
motions are mixed, you can pass the mix on to
other biped (if it contains BIP files) and non-biped
objects (if it contains XAF files), or save the mix
to a
.mix file.
Blending Motions in the Mixer
The Motion Mixer provides these t yp es of motion
blending.
• You can blend motion from one clip to another
with a
transition (page 3–1121) . Transitions
in the Mixer are similar to those used in
