Final Step Update group
The Final Step Update script is executed after the last integration step has been
completed for each frame that you view (or render). For example, if you play
the animation in the viewport with Real Time turned off, Particle Flow runs
this script at each frame, immediately before the particle system is rendered
to the viewport. However, if you simply jump to a different frame, the script
is run once only, so if the script assumes a certain history, you might get
unexpected results.
For this reason, it's best to use the Final Step Update script to modify
history-independent properties. For example, if no operators in the system
depend on the material indices, you could use it to modify the material index.
In this case there's no need to set those indices in every intermediate
integration step. Also, you can set up a position channel in the Final Step
Update script if you know the analytical expression for the position.
Enable Script Turn on to cause a script in memory to be executed after the
final integration step. You can modify this script by clicking the Edit button,
or load and use a script file with the remaining controls in this group.
The default script modifies particle speed and direction, causing particles to
follow a bulb-shaped path.

When Use Script File is off, this is the default Final Step Update script
(3dsmax\scripts\particleflow\example-finalstepupdate.ms). When Use Script File is

displays the Open dialog.
