Chapter 2 Creating and Managing Projects 205
The project shown in the following image contains a particle system. Notice that the
animated particles, although not visible once they move off the Canvas, make the layer
very large.
When you want to apply filters to objects that are growing in size, it is recommended
to apply those filters to the objects’ enclosing layer. When filters are applied to very
large layers, or large layers are used as the source object for other objects, processing
time is slowed. You can crop the size of a layer that contains growing objects using the
Fixed Resolution parameter, located in the Layer tab of the Inspector.
