pelvis and spine when you use different motions
on the upper and lower parts of the biped. See
Adjusting Biped Balance in the Mixer (page 2–622) .
Note: This dialog is available only for biped object
mixes.
• Lateral R atio—Decreasing the Lateral Ratio
to 0.0 will cause balance compensation to
use only forward/backward motion on the
pelvis. Increasing Lateral Ratio to 1.0 will
adjust the pelvis with only side-to-side motion.
Range=0. 0 to 1.0; Default=0.5.
•
Propa gation—Affects the degree to which
spine links are rotated to follow COM and
pelvis rotat ion. When set to 0.0 (the default),
spine rotation is not influenced by lower body
motion. When set to 1.0, all spine links except
thetopmostoneusethelowerbodymotion’s
spine animation to some degree to better follow
theCOMandpelvismotion.Thelowestspine
link is rotated the most, and each subsequent
spine link is rotated less and less. The topmost
spine link is not rotated at all so ar m motion
wi ll be preser ved.
In order for this setting to affect spine rotation,
the lower b ody motion must have some spine
animation as p art of the motion clip.
A Propagation setting above 0.0 is appropriate
when the upper b o dy mot ion causes the spine
to bend over a great deal during a large part of
the animation. Range=0.0 to 1.0; Default=0.0.
Delete—Clears the selected object(s) f rom the
Mixer.
Load Mix File—Opens a dialog where you can select
a M IX file (page 3–973) to load into the Mixer.
Save Mix File—Opens a dialog where you can save
the current object’s mix (page 3–972) to a MIX file.
The following Mixdown-related tools ar e available
only for biped object mixes.
Co mpute Mixdown—Performs a mixdown (page
3–973) on the selected biped(s). A Mixdown
track appears at the bottom of each biped’s
mix. Clicking the Mixdow n track deactivates or
activates it. When the Mixdown track is active,
each biped inherits this sing le track’s animation
rather than the transition and layer tracks i n the
mix. When the Mixdown track is inactive, the
biped uses the raw mix (page 3–972) instead.

Creating a Mixdow n track makes it possible to
copy the mixdown to the biped so it can be saved
as a BIP file. See Exporting Animation to the Biped
(page 2–624).
Delete Mi xdown—Removes the mixdown f rom the
mix of the selected biped(s).
The next three menu options are mutually
exclusive; only one can be turned on at a time.
Co py Mi xdo wn to Bipe d—Copies animation from
theMixdowntracktothebiped.Theanimation
remainsonthebipedevenafterMixermodeis
turned off, and the animation can be saved as a
BIP file.
Effect R aw M ix—When this option is turned
on, Mixer mo de is turned on for the biped.
Default=active.
