8.4. Editing a subcomposition

You can recognize a subcomposition node by the icon in its top-right corner. The icon consists of two overlapping squares, symbolizing that the subcomposition node has a composition inside of it that you can view and edit.

You can open that composition by double-clicking on the subcomposition node on the canvas, or by right-clicking on the subcomposition node on the canvas or in the Node Library and choosing Edit Composition.... When you save changes made to the subcomposition, the changes apply everywhere the subcomposition is used — every instance of the subcomposition node in the composition you have open, and all other compositions that contain the subcomposition.
