Apply filters to particle systems
Filters can be applied to a particle system’s emitter, but not to individual cells. (However, filters
can be applied to the source of a cell.) Consequently, filters affect the entire particle system,
including every element in the onscreen pattern.

Particle system examples
Example 1: Create an animated background
This example shows how to create an animated background using a single still image. By using
the parameters available in the Emitter Inspector, a single image can be turned into a complex
animated texture.
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 button in the toolbar (or press E).
When you add an emitter to the project, the following occurs:
•
The emitter appears in the Layers list and is selected.
•
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.
