# lightingModel

The lighting formula that SceneKit uses to render the material.

## Declaration

```swift
var lightingModel: SCNMaterial.LightingModel { get set }
```

## Discussion

Discussion SceneKit provides several different lighting models, each of which combines information from a material’s visual properties with the lights and other contents of a scene. For details on how each lighting model affects rendering, see Lighting Models. For details on the contribution from each visual property, see Visual Properties for Special Effects.
