Chapter 8 Working With Particles 579
4 To make the particles drift upward, click in the middle of the Emission Range segment
and drag to rotate the emission angle up and slightly to the right of the center control.
5 As you drag the middle of the Emission Range segment, you can drag toward, or away
from, the center of the Emission control to adjust the speed of the particles flying away
from the emitter. As you make this adjustment, one or more arrows within the currently
defined emission range become longer to indicate a faster speed, or shorter for a
slower speed.
6 Drag the Speed arrow so that it is approximately halfway between the center and the
edge of the Emission control to create a slowly drifting column of particles.
7 At this point, the particles are all moving in the correct direction, but there aren’t very
many of them (there isn’t much of a fire yet). Move the Birth Rate slider to the right, to
increase the number of particles created by the emitter.
