Replicators and Rasterization
When a group becomes rasterized, all layers within that group—including replicators—are
affected and may no longer interact with other layers and groups as expected.
Note: A replicator can be rasterized independently of the group in which it lives. This
affects how the replicator interacts with objects within its own group. For example,
applying a Circle Blur filter to a replicator causes the replicator to no longer intersect with
other objects in the same group. The same operations that cause a 3D group to rasterize
cause a 3D replicator to rasterize. To minimize this effect, apply the filter directly to the
replicator’s source object, or deselect the 3D checkbox in the Replicator tab.
In the following illustrations, the nonrasterized 2D group that contains the replicator is
set to the Add blend mode. The replicator interacts with the group beneath it in the layer
stack.
The Elements group is not rasterized. The replicator blend mode interacts with the
group beneath it in the project.
