This tells the software to start the script with this clip, and uses the default
probability of 100 percent that the clip will be chosen.
If you want the various bipeds to start with different clips, select multiple
random start clips by pressing and holding the Ctrl key as you click. The
default Random Start Probability setting of 100 for all clips means that
the software will choose randomly among them for a starting clip for
each biped's script.
To change the likelihood of starting with specific clips, right-click a clip
and modify its Random Start Probability setting. For example, say you
want to start each biped's script with any of three clips: clips A, B, and
C. You want clip A to be chosen twice as often as clip B or C. In that case,
using the Random Start Clips tool, you'd first click clip A, and then
Ctrl+click clips B and C. Then you'd right-click each in turn, assigning a
Random Start Probability of 60 to clip A, and 30 to both clips B and C.
NOTE The Probability values are arbitrary; what counts is their ratios. For
example, values of 80/40/40 or 20/10/10 would work the same.
NOTE You can also set and change random starting clips and start
probabilities in the Motion Flow graph after loading the MFE file into the
Shared Motion Flow dialog, described later in this procedure.
NOTE If a motion flow script already exists for a biped, for example after
you've solved a crowd simulation, the software can use the first clip in the
script for subsequent solutions.
9 In the Motion Flow rollout, click the Save File button, and save
the graph in the MFE format.
The next step in using bipeds in a crowd simulation is to create the
simulation.
To set up the crowd simulation:
1 Reset 3ds Max.
2 Set up a crowd simulation with any number of delegates, using behaviors
appropriate to the crowd scene you want to create. Do not use bipeds at
first; work with delegates only to rough out the motion of the crowd
members.
