the current script is red. Transitions are shown as arrows between clips, red
arrows represent the path through the active script. Black transition arrows
indicate unloaded scripts. A transition looping back to the same clip represents
a cycle or loop.
If the biped is using a shared motion flow, then the title of the graph window
will say "*SHARED* Motion Flow Graph", followed by the name of the shared
motion flow. Shared Motion Flows are used to control multiple bipeds with
one shared motion flow.
By default, minimum motion loss is used to compute transitions. Optimized
transitions use an algorithm that uses minimum foot sliding. Optimized
transitions take longer to compute but yield very high quality results.
Random Scripts for One or More Bipeds
You can create random scripts by using the Create Random Motion command
in the Script group on the Motion Flow rollout. Random scripts are created
by randomly traversing clips in a motion flow graph. To use Create Random
Motion, each biped must be in the same shared motion flow.
To use a shared motion flow to create random scripts for multiple bipeds, the
first step is to click Shared Motion Flow on the Motion Flow rollout, and then
add bipeds that will share one shared motion flow. On the Motion Flow Graph,
clips are added and transitions are created between all the clips. Then Create
Random Motion is used to compute a random motion for all the bipeds.
Clips and transitions are given percentages that are used by the software to
generate random scripts. Percentages for clips and transitions are set in the
clip dialogs and in the Transition Editor dialog.
You can load many clips and use Create All Transitions to create all possible
transitions between the clips. You can then use Optimize Selected Transitions
to create optimized transitions. Once the transitions are created, you can
quickly create scripts with optimized transitions or generate random motions
for a crowd of bipeds.
The MFE file stores pointers to the clips, transition parameters, and scripts.

the graph, or

and transitions.
