# automaticallyUpdatesLighting

A Boolean value that specifies whether ARKit creates and updates SceneKit lights in the view’s scene.

```
var automaticallyUpdatesLighting: Bool { get set }
```

## Discussion

If this value is <doc://com.apple.documentation/documentation/Swift/true> (the default), the view automatically creates one or more <doc://com.apple.documentation/documentation/SceneKit/SCNLight> objects, adds them to the scene, and updates their properties to reflect estimated lighting information from the camera scene. Set this value to <doc://com.apple.documentation/documentation/Swift/false> if you want to directly control all lighting in the SceneKit scene.
