# shininess

The sharpness of specular highlights. Animatable.

## Declaration

```swift
var shininess: CGFloat { get set }
```

## Discussion

Discussion The shininess of a material interacts with its specular property and the lighting in a scene to produce bright highlights on a surface. A higher value produces more sharply defined highlights, making a surface appear more smooth and glossy. You can animate changes to this property’s value. See Animating SceneKit Content.
