```
var cameraScaleReference: Float { get }
```

## Discussion

Returns the camera scale reference of a pixel with rgb value [1,1,1] in the environment texture.

In order to have a consistent brightness between texture updates, the cameraScaleReference allows you to translate the local brightness from the current environment texture to the absolute brightness range from the camera.
