Correcting Posture
A particular motion file might position a biped body part inappropriately. For
example, the collarbones might be rotated down too far, affecting your mesh
deformation. All you need to do is go into Figure mode, rotate the biped
collarbones up, and then exit Figure mode: this corrects the collarbone position
for the entire animation. The motion references the Figure mode position, if
the biped is adjusted, and this adjustment is reflected in your animation when
you exit Figure mode.
TIP Save a FIG file for the biped pose you used when you applied Physique. Then
you can use the FIG file to reload this position if you need to reapply the Physique
modifier or reinitialize the Physique settings.
How Biped Uses Figure Mode
When you animate the biped, the Biped plug-in maintains the at-rest pose
you have created for these elements of the biped body:
■ Spine
■ Neck
■ Clavicles
■ Tail
■ Ponytails
■ Center of mass position, relative to the body.
When Biped adapts the keyframed motions stored in BIP files to different
characters, the keyframes of the above elements are recreated as an offset from
the at-rest posture associated with each character's figure. The at-rest posture
associated with the arms and legs is always assumed to be a standing posture,
with straight legs.
Restructuring a Biped to Match a BIP File
When you load a BIP file, there is an option to restructure the biped to match
the file. If you turn this on when you load the file, the biped’s structure will
change to match the figure of the biped in the BIP file.
