Command entry: Particle View 
Click Script Operator in an event or add a Script Operator to the particle system and then select it.
The Script operator enables control of particles within the Particle Flow system using a MAXScript script. The script can
use any program functionality available to MAXScript.
When you add a new Script operator, it contains a default script that slows particles, and then, when they are slow enough,
splits off the first 50 particles into a stream traveling in a negative direction on the world X axis, and the remainder traveling
in the opposite direction.
TipYou can use MAXScript to align particle scale with the underlying bitmap, thus providing a “scale bitmap” function. This requires
a sandwich with three operators: two Script operators, and a Speed By Surface operator in between. The first Script operator
reads the current speed vector into the MXVector channel, thus caching the current speed. The Speed By Surface operator changes
the speed according to the underlying bitmap. And the second Script operator reads the speed channel into a temporary variable,
restores the speed from the MXVector channel (the cached value), and uses the temporary variable to define the scale. This
way, the original speed is restored, and the scale value is defined by the bitmap.
Interface
The user interface appears in the parameters panel, on the right side of the Particle View dialog.
- Edit Script
-
Click this button to open the current script in a MAXScript Editor window.
For detailed information about the MAXScript utility, open the MAXScript Help, available from Help menu MAXScript Help.
Uniqueness group
The Uniqueness setting provides a randomization seed that the script can use or ignore.
- Seed
-
Specifies a randomization value.
- New
-
Calculates a new seed using a randomization formula.
