Chapter 14 Particles 552
•
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 the bounding box for the emitter.
•
The Emitter HUD appears. 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) might 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 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 Inspector, 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.
•
Select Additive Blend.
•
Set Color Mode to Pick From Color Range. (Or, if you prefer, select another gradient from the
preset pop-up menu.)
•
Set Scale to 65%.
•
Set Scale Randomness to 150.
•
Set Random Seed to 10000.
•
Advance to frame 100.
The resulting image now looks similar to this:
