character studio provides two main ways of combining BIP files to build more complex character animations: Motion Flow and the Motion Mixer.
Motion Flow uses BIP files as clips in a script. The motion-flow script joins clips together using transitions. Transitions can be unconditional, they can be chosen at random, or they can be governed by rules such as collision detection.
You can control when a transition begins and ends. You can use motion flow to animate a single biped, or a crowd of bipeds.
Motion flow scripts are saved as Motion Flow Editor (MFE) files.
The Motion Mixer also uses BIP files and MFE files as clips. In addition to creating transitions from one BIP animation to another, over time,
Mixer scripts can combine the upper-body movement of one biped with the lower-body movement of another, adjust the timing
of movements, and provide a number of other effects. The Mixer is especially useful when you work with motion-capture files.
Mixer scripts are saved as BIP files or MIX files.
