Note: You can also use a group as the source for an emitter cell, but keep in mind that
your project’s interactivity may slow drastically.
To create an emitter:
1 Place a layer that you want to use to generate particles into your project.
This example uses an image of a simple white circular gradient, such as the “basic
blur.png” image located in the Library (in the Particle Images subcategory of the

2 Move the layer in the Canvas to the location where you want the center of your particle
system to be.
3 Select the object, then do one of the following:
 In the Toolbar, click the Make Particles icon.
 Press E.
