About Scenes in Web Control Center
After you create a scene, you can view some of the scene information in the Scenes list, such as the version, number of frames and status.
NOTE: It is useful to have at least one Display node in your scene as it dictates what is displayed in the movie and thumbnail of the selected scene.
NOTE: Add more categories to the Scenes list by clicking the plus (+) icon at the top-right corner and selecting items to view—see Scenes List.
NOTE: When selecting scenes from the Scenes list, there is a delay for the first preview/thumbnail update because it is done in batch render.
