Particle System Examples
This section presents two examples of how to use particle systems to create very
different effects. The particle system created in the second example is turned into a 3D
particle system after the “pixie dust” is animated.

Tip: You can use the Make Clone Layer command to clone an emitter and then use the
Retiming controls or Retiming behaviors to create unique animations. For example, you
can create a starburst that explodes outward, then retracts, then explodes, and so on.

Example 1: Creating an Animated Background
This first example describes how to create an animated background using a single still
image. By using the parameters available in the Emitter tab, a single image can be
turned into a complex animated texture. Once the example is created, quickly turn the
system into 3D particles using the 3D checkbox in the Emitter tab of the Inspector.
To create an animated background from a single image:
1
Drag a file into the Canvas.
This example uses a simple star graphic.
2
With the new layer selected, click the Make Particles icon in the Toolbar (or press E).
Once an emitter is added to the project, the following occurs:
 The emitter appears in the Layers tab and is selected.
