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.
When you animate the biped, the Biped plug-in maintains the at-rest pose you have created for these elements of the biped 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.
Talent Figure Mode and Adjust Talent Pose
Talent Figure Mode and Adjust Talent Pose on the Motion Capture rollout have a purpose similar to that of Figure mode. They are used to size and position biped body parts to better fit raw motion capture data. After importing motion capture data, you might discover that certain biped limbs or the biped scale need a global adjustment in order to provide a closer match to the figure of the talent who performed the motion.
