856 Chapter 10 Using Filters
Rasterization affects 2D and 3D groups in different ways. When a 2D group is rasterized,
the blend modes on objects within the group no longer interact with objects outside of
the group. In addition, when a 3D group is rasterized, the group as a whole can no
longer intersect with objects outside of the group. The rasterized 3D group is treated as
a single object and uses layer order, rather than depth order when composited in the
project.
For more information on rasterization and 3D groups, see "3D Compositing" in the
Motion Supplemental Documentation PDF.
Note: When a group is rasterized, cameras and lights in the project still interact with
objects within the rasterized group.
Once an operation triggers a rasterization on 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.
The following filters force rasterization of 3D groups:
