Particles

As you drag, both points defining the emission range rotate symmetrically around the center of
the emission control. When the emission range forms the rightward angle shown below, release
the mouse button. (As you adjust the emission range, the particles rearrange themselves in the
Canvas, enabling you to see the resulting effect.)

To make the particles drift upward, drag in the middle of the Emission Range segment, rotating
the blue arrow counterclockwise until it points up and slightly to the right of the center control;
continue dragging outward to lengthen the arrow.
The angle of the arrow controls the emission angle of the particles. The length of the arrow
controls the speed of the particles. The longer the arrow, the faster the particles.
4
In the Emitter HUD, drag the Birth Rate slider to the right to increase the number of particles
created by the emitter.
As you increase the birth rate, more particles are created, forming a nearly unified column of
“smoke.” The particles move farther apart as they drift away from the emitter.
Although the HUD controls are quite powerful, the Emitter and Particle Cell panes in the
Inspector have many more parameters you can customize. For more information, see
on page 526 and
on page 536.
