Chapter 8 Working With Particles 583
As shown in the following images, you can apply masks to the cell source object of a
particle emitter.
You can also apply masks to the emitter object itself.
For more information on working with masks, see “
Masking an Object” on page 851.
Timing
Once you create a particle system, its duration can be as long or short as necessary,
regardless of the duration of the original objects used to create the particle system. The
duration of a particle system is defined by the duration of the emitter object. Changing
the In or Out point of an emitter in the Properties tab, Timeline, or mini-Timeline
changes the duration of the entire particle system.
By default, particles are generated by every cell in a system over the entire duration of
the emitter. The duration of each individually generated particle is defined by the Life
parameter of the cell that generated it, and not by the duration of the cell itself.
