 A small outline appears around the rasterized 2D group, 3D group, emitter, replicator,
or text icon (to the left of the group name) in the Layers tab and Timeline layers list.
Note: Because a paint stroke is always rasterized, no rasterization indicator appears
around the paint stroke icon.
For more information on rasterization and 3D groups, see “ 3D Compositing ” in the
Motion Supplemental Documentation PDF.
