A background to be rendered before the rest of the scene.
- iOS 8.0+
- macOS 10.9+
- tvOS 9.0+
- watchOS 2.0+
If the material property’s
contents object is
nil, SceneKit does not draw any background before drawing the rest of the scene. (If the scene is presented in an
SCNView instance, the view’s background color is visible behind the contents of the scene.)
If you specify a cube map texture for the material property (see the discussion of the
contents property), SceneKit renders the background as a skybox.
