name

The name of a scene file in the app bundle.

directory

The path to the subdirectory of the bundle’s resources directory containing the scene file.

Discussion

This method provides a convenient way to load a complete scene from a file in the app’s main bundle. Calling this method is equivalent to using the Bundle class to locate the scene file and passing the resulting URL to the init(url:options:) method.

For more detailed options or to load only part of a file’s scene graph, use the SCNSceneSource class.

When creating a scene using Xcode's Scene Editor or an external tool, you should copy your scene file into a directory with the .scnassets extension inside your app bundle. You should also place any image files referenced as textures from that scene in an Asset Catalog. Xcode will optimize the scene and texture resources for best performance on each target device, and prepare your texture resources for delivery features such as App Thinning and On-Demand Resources.
