Rasterization Indicator

In the Properties tab of the Inspector, a small “LED” icon appears when a group is rasterized. This is called the rasterization indicator. This is not a control, but rather an indicator to alert you that a group has been rasterized.

Some operations, as well the application of certain 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 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 being composited in the project.

Once an operation triggers a rasterization on a group, the rasterization indicator appears next to the parameter in the Properties tab.

Additionally, a small frame appears around the 2D or 3D group icon (to the left of the group name) in the Layers tab and Timeline layers list.
