Restrictions
Some features of the crowd system are not designed to work with biped crowds.
These behaviors and parameters have no effect on the crowd's movements
when bipeds are used with the simulation.

Procedures: Using Bipeds in a Crowd Simulation
The following sequence of procedures gives the basic steps for creating and
saving a motion flow graph, assigning several bipeds to delegates, and then
sharing the motion flow graph among the bipeds so that the software
automatically creates separate motion flow scripts for each biped, based on
the behaviors assigned to its delegate.
NOTE These procedures assume you know how to animate bipeds with footsteps
and keyframe methods, and save the animations as BIP files. To prepare for using
Shared Motion Flow, you should create and save a range of biped motions such
as start, walk, turn right, turn left, stop, and wait. See
Loading and Saving BIP
Animation
on page 4300.
The first step is to create an appropriate motion flow graph and save it to disk.
To create the shared motion flow:
1
Add a biped, and then open the Motion panel.
2 Click the Biped rollout > Motion Flow Mode button.
3
Click the Motion Flow rollout > Show Graph button.
4 In the Motion Flow Graph toolbar, click the Create Multiple Clips
button.
This displays an Open dialog that lets you select any number of BIP files
from the same directory to add simultaneously to the motion flow graph.
