742 Chapter 8 Working with Particles
 A cell containing the image to be “particle-ized” appears underneath the emitter.
 The original source layer (cell source) is disabled.
 In the Canvas, the emitter bounding box appears, which can be transformed using
the onscreen controls.
 The first particle appears in the Canvas in the same location as the original object.
Although it appears as if the particle is selected, it is actually the bounding box for
the emitter.
 The Emitter HUD is displayed. If you have hidden the HUD, press D or F7.
Note: For projects with a frame rate greater than 30 fps, at times only the bounding
box (not the particle cell) may appear at the first frame of your project. Because
particles are generated at a rate of 30 per second, there is no guarantee a particle will
appear on every frame.
3 In the Emitter tab of the Inspector, choose Circle from the Shape pop-up menu.
4 Choose Tile Fill from the Arrangement pop-up menu.
5 In the Cell Controls section of the Emitter tab, set the Initial Number parameter to 12.
This creates a distributed group of particles that partially fills the Canvas.
6 To turn the particles into a uniform abstract mass, adjust the following parameters:
 Set Life to 4.
 Set Speed to 140.
 Set Spin to 60.
 Set Spin Randomness to 15.
 Turn on Additive Blend.
 Set Color Mode to Pick From Color Range. (Or, select another gradient from the
Preset pop-up menu if you prefer.)
 Set Scale to 65%.
 Set Scale Randomness to 150.
 Set Random Seed to 10000.
