Birth Script Operator

The Birth Script operator enables creation of particles within the Particle Flow system using a MAXScript script. The script can use any program functionality available to MAXScript.

• Particle View > Click Birth Script in an event or add a Birth Script operator to the particle system and then select it.

The default script (3dsmax\scripts\particleflow\example-scriptbirth.ms) emits particles for 100 frames in a wavy, circular path. To see this, turn off or delete any Speed and Position operators in the event.

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.
