Shared Motion Flow (page 2–1056) allows you
toassignonemotionflowtomultiplebipeds
or crowds. Rather than building a motion flow
network of clips for each biped, you can create
amotionflowwithalltheclipsandtransitions
toanimatemultiplebipeds. Randommotion
creat ion will use each biped’s own motion flow.
If a biped’s mot ion flow happens to be a shared
motion flow, then the shared motion flow will be
used to compute random motion.
Abipedthatsharesamotionflowsharesonlythe
clips you have added to the Motion Flow Graph.
Scripts are unique to each biped, although the
scripts point to the clips of the shared motion flow.
You can manipulate each biped’s motion flow and
scripts in t he usual ways. You can create ra ndom
motion on a biped that shares a motion flow, or
create a motion flow script using the crowd system.

that biped’s motion flow graph, the title of the
graph dialog will say "Shared Motion Flow Graph",
followed by the name of the shared motion flow.
Note: All bipeds in a shared motion flow should

for differently sized bipeds does not occur in a
shared motion flow. If you want differently sized
bipeds in a crowd, then create a shared motion
flow for each size.
Tip: The only way to save a shared motion flow,
alongwiththebipedssharingit,andkeep
everything hooked up correctly is to save it all in
a .max file.
Procedure
Example: To share a random motion f low among
multiple bipeds:
1.
Create three bipeds.
2. On the Biped rollout, turn on Motion
Flow Mode .
3. On the Motion Flow rollout, click Show
Graph.
This displays the Motion Flow Graph.
4. ClickCreateMultipleClipsandaddat
least four clips to the Motion Flow Graph.

the loc at ion of your .bip files.
5. After adding the clips, click Move Clips
and arrange the clips so they are not so close to
oneanother.Thiswillmakeiteasiertoseethe
transitions later.
6. Click Select Clip/Transition and region
select all the clips.
7. On the Motion Flow Graph, click
Synthesize Motion Flow Graph and click Yes
when asked if you want to create transitions
from each selected clip to itself.
