Declaration
var ambientOcclusion: SCNMaterialDiscussion
Use this property to assign an ambient occlusion texture map to a surface. This property has no effect if there is no ambient light in the scene. If this property is not nil, SceneKit ignores the ambient property.
When using physically-based shading (see physically), ambient occlusion approximates large-scale surface details that obscure global illumination.
