Show/Hide cameras in the scene
Enable or disable this option to show or hide all user-created cameras in the Scene Pane listing
Toggles viewing user-created cameras within the Scene Pane on and off (default views and cameras, aside from Default Camera, do not appear in the Scene Pane). A checkmark appears next to this option when it is enabled. Clearing this checkbox removes all user-created cameras from the Scene Pane tree view, and vice-versa.
