Definition
An overlay is a 2D image (often a logo) that is displayed in front of the objects in the 3D world. It does not move when you navigate in the 3D world, but remains stationary with regard to the screen.
Overlays are associated with camera sensors. For more information on how overlays are created and applied, see Overlays (Editor) and Sensors.
Overlays are managed in the Matter sidebar's overlay library.
