Examples of 2D Group and 3D Group Rasterization
In the example above, there are two groups: The first group (topmost in the Layers list)
contains the image of a lone elephant. The second group contains the image of a
family of elephants. In the left example above, the single elephant image—in the
topmost group—has its Blend Mode set to Vivid Light. Because the group is not
rasterized, the Blend Mode passes through the group and operates on the background.
In the right example above, the topmost group is rasterized, so the elephant image’s
Blend Mode no longer passes through the group.
In the left example above, Group A and Group B intersect because they are not
rasterized.
In the right example above, Group A has been rasterized, so Group A and Group B no
longer intersect.
Important: If a group’s Blend Mode is set to Pass Through and any of the group’s
children have different Blend Modes applied, the children are not rasterized.
