# referenceURL

The URL to a scene file from which to load content for the reference node.

## Declaration

```swift
var referenceURL: URL { get set }
```

## Discussion

Discussion When the reference node loads its content (either automatically, according to the loadingPolicy property, or when you call the load() method), SceneKit loads the referenced scene file. All children of the scene file’s root node become children of the reference node.
