Using Particle Systems
Despite their sophistication, particle systems are easy to set up and simple to use. This
section describes how to use pre-made particle systems from the Particle Emitters
category of the Library. Afterward, this section explains how to create a simple particle
system of your own.
Particle Systems and Layer Sizes
Particle systems often create particles that grow or move off the Canvas before they
die. This can make the size of a layer or group much larger than that of the Canvas.
Although the particles are not visible once they move off the Canvas (unless Show
Full View Area is turned on in the View menu), they are still present in the project and
are processed. If you apply a filter to a layer containing growing particles, or use that
layer as a source object, it is recommended that you turn on the Fixed Resolution
checkbox in the Group tab of the Inspector (available only when a group is the
selected object). The Fixed Resolution parameter allows you to set the specific width
and height of a group, cropping anything beyond those values. For more information,
