Delete K eys before Solve—
Deletes the keys of active
delegates in the range over which the solution
takes place. Default=off.
This option leaves the first two keys so that the
delegate doesn’t end up with no keys and then
pop to its current position. This is a useful feature
for biped crowds; it lets you watch each biped
compute, one after another , without the ones not
yet computed still performing their old animation.
Sav e every Nth K ey —Lets you specify the number
of position and rotation keys saved after the
solution.
Positions/R otations—The f requency w ith which
keys are saved for delegate positions and rotations.
If 0, no keys are saved. If 1, a ke y is saved every
frame. If 2, a k ey is saved every other frame, and
so on. Defaults=1.
Display During Solve group
Update display —When on, motion produced
during solution of a crowd simulation appears in
the viewp orts. Default=on.
Fr equ e n cy—How often the display is updated
duringthesolution.If1,theupdateoccursevery
frame. If 2, the update occurs every other frame,
and so on. Default=1.
Vector Scale—Globally scales all force and velocity
vectorsthataredisplayedduringthesimulation.
Default=10.0.
Scaling vectors up help s to see them better
when they are very small. It does not effect the
simulation.
MAXScript group
This feature lets you execute a MA XScript script at
each frame. Its primary purp ose is for working
with bipeds; specifically, to take advantage of
available MAXScript calls to Biped that let you
specify which clip the biped will be likely to choose
next when using the shared motion flow feature.
With this feature, you can write a script that
dynamically selects the biped’s next clip during the
Crowd simulation, based on which clip is currently
being used, the frame number, the proximity of
other bipeds, or anything else that you can find out
in a scr ipt. Of course, this scripting feature can be
used for other purposes as well.
Use M A XS cri pt —When on, a user-specified scr ipt
is executed at each frame during the solution.
Default=off.
Function N ame—Thenameofthefunctiontobe
executed. This name must also specified in the
script.

the script.
Bipeds group
When solving simulations that use bipeds linked
to delegates, it is strongly recommended t hat you
use al l three options in this group.
Biped/Delegates Only—When on, only
biped/delegates are included in the computation.
Also, the options to use priorities and backtracking
become available. These options are available only
for biped-only computations. Default=off.
Use Prior ities—When on, biped/delegates are
computed one delegate at a time, in order of their
Priority values, from lowest to highest. Also,
backtracking becomes available, and Step Solve
becomes unavailable. Default=off.
Backtracking—Turns on backtracking
functionality when solving a crowd simulation
that uses bipeds. D efault=off.
When Backtracking is on during the solution, in
the case of an impending collision between bipeds,
the Crowd system will back up the simulation
