- watchOS 3.0+
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.
