See `Scene Loading Options` for available keys and values. Pass `nil` to use default options. ## Return Value An initialized scene source object, or `nil` if initialization was not successful. ## Discussion If you have the contents of a scene file but not the file itself (for example, if your app downloads scene files from the network), use the [`init(data:options:)`](/documentation/SceneKit/SCNSceneSource/init(data:options:)) method instead. ## See Also [`+ (instancetype) sceneSourceWithURL:(NSURL *) url options:(NSDictionary *) options;`](/documentation/SceneKit/SCNSceneSource/sceneSourceWithURL:options:) Creates a scene source that reads the scene graph from a specified file.
