38 Chapter 1 3D Compositing
Changes to the following parameters trigger rasterization of a group:
2D Groups
 Making Blending changes (Opacity, Blend Mode, Preserve Opacity)
 Turning on Drop Shadow
 Turning on Four Corner
 Turning on Crop
 Applying any filter
 Adding a mask
 Adding a light outside of a group
3D Groups
 Blending changes
 Applying certain filters
 Adding a mask
 Adding a light outside of a 3D group with the Flatten parameter enabled
Once an operation triggers rasterization of a group, the following occurs:
 A rasterization indicator (resembling an LED) appears next to the parameter in the
Properties tab.
 A small outline appears around the 2D or 3D group icon (to the left of the group
name) in the Layers tab and Timeline layers list.
Important: 3D particle emitters, 3D replicators, and non-flat text objects are treated as
3D groups for the purposes of rasterization.
