You??™ll
learn how to make that happen in the next exercise.
Controlling Particles
It isn??™t necessary to always move the particle emitter to see moving particles. The particles
can move on their own in a variety of ways. This next section shows you how to create
a particle stream to simulate smoke, and with minor modifications, is also good for
water fountains, molten lava, gooey chocolate, and more.
Exercise 13.2 Controlling Particle Flow
1. Select Clear Scene from Layout??™s File drop-down.Make sure Auto Key is active,
and then add a new particle emitter as you did in Exercise 13.1. Name it ???smoke???
when the Add Particle Emitter dialog box appears.
2. For the Emitter Type setting in the Add Particle Emitter dialog box, choose
HV Emitter.
You??™ll notice that the particle emitter (named ???smoke???) is a set size. You can scale
it down to fit objects in your scene.With smoke, such as you??™ll be creating here,
the emitter is often a small, concentrated point of origin, such as a pipe or cigar.
3. When the FX_Emitter panel appears, move it aside as needed, so you can see the
emitter in the scene (Figure 13.
