Some operations, as well as the application of specific filters or a mask, cause a group to
be rasterized. When a group is rasterized, it is converted into a bitmap image. 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 the group.
When a 3D group is rasterized, the group cannot intersect with objects outside the group.
The rasterized 3D group is treated as a single object and uses layer order, rather than
depth order when being composited in the project.
When the adjustment of a parameter triggers rasterization of a group, a rasterization
indicator appears to the left of that parameter’s name in the Properties Inspector.
Additionally, a frame appears around the 2D or 3D group icon (the stack icon to the left
of the group name) in the Layers list and Timeline.
