The Background Render Element stores an image of the texture used in the background behind geometry in a scene as seen from the camera. Geometry that blocks the background image renders as black.

This render element interprets a background texture, such as the texture set in the Environment Overrides, as a background.

Other types of manually created backgrounds, such as a plane, mapped with a texture set outside a window, will not interpreted to be a "background" for the purposes of this render element.
