Declaration
var lightingEnvironment: SCNMaterialProperty { get }Discussion
When rendering materials with the physicallyBased lighting model, SceneKit illuminates surfaces differently according to the environment that surrounds them. For example, with physically based shading, even a diffuse surface takes on some color from the sky above it and the ground below it.
For information about defining cube maps, see the discussion of the contents property.
