# referenceURL

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

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

## Discussion

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