# rendersCameraGrain

A flag that determines whether SceneKit applies image noise characteristics to your app’s virtual content.

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

## Discussion

Enabled by default. When set, SceneKit adds a camera grain effect to your app’s virtual content that matches the image noise characteristics ARKit observes in the camera feed.
