• Turning on the Crop parameter
• Applying any filter
• Adding a mask
• Adding a light (if the 2D group the light is added to is nested in a 3D group)
The following operations on a 3D group trigger the rasterization of that group:
• Making blending changes
• Applying specific filters
For more information, see
Filters and Rasterization
• Adding a light to a 3D project with the Flatten parameter enabled (in the Group
When an operation triggers a rasterization on a group, the following occurs:
• A rasterization indicator (a small red box containing an “R”) appears next to the
parameter in the Properties Inspector.
• A small outline surrounds the rasterized group in the Layers list and Timeline. This is
called a rasterization frame.
Note: Unlike vector graphics, rasterized 2D groups may lose quality when scaled if the
Fixed Resolution checkbox is selected in the Group Inspector.
3D particle emitters, 3D replicators, and nonflattened text objects are treated
as 3D groups for rasterization.
