Part X: Dynamic Animation
180 emits particles in the opposite direction. The Spread value can range from 0 to 180 degrees and fans
the particles equally about the specified axis. The Off Plane value spins the particles about its center axis,
and the Spread value sets the distance from this center axis that particles can be created. If all these values
are left at 0, then the particle system emits a single, straight stream of particles, and if all values are 180,
then particles go in all directions from the center of the emitter icon.
FIGURE 41.4
The Basic Parameters rollout lets you specify where and how the particles appear in the viewports.

The icon size can be set or the icon can be hidden in the viewport. You also can set the particles to be dis-
played in the viewport as Dots, Ticks, Meshes, or Bounding Boxes. The Percentage value is the number of
the total particles that are visible in the viewport and should be kept low to ensure rapid viewport updates.

Particle Generation rollout
The Particle Generation rollout, shown in Figure 41.5, is where you set the number of particles to include
in a system as either a Rate or Total value. The Rate value is the number of particles per frame that are gen-
erated. The Total value is the number of particles generated over the total number of frames. Use the Rate
value if you want the animation to have a steady stream of particles throughout the animation; use the Total
value if you want to set the total number of particles that will appear throughout the entire range of frames.
