locksAmbientWithDiffuse
A Boolean value that determines whether the material responds identically to both ambient and diffuse lighting. Animatable.
Declaration
var locksAmbientWithDiffuse: Bool { get set }Discussion
When modeling real-world lighting, a surface is typically considered to have a single “base” color or texture that is visible under both ambient and diffuse light. When this property’s value is false, SceneKit does not have this limitation: you may use a material’s diffuse property to provide a color or texture that is visible under direct lighting, and its ambient property to provide a different color or texture for areas not directly illuminated.
When this property’s value is true, or when using the physicallyBased shading mode, SceneKit uses the diffuse property for ambient lighting, ignoring the ambient property and ensuring that the material responds identically to both ambient and diffuse light.
The default value for this property is true for new apps on all platforms. (In OS X v10.9 and earlier, the default value is false.)
You can animate changes to this property’s value. See Animating SceneKit Content. Animating this property fades between the results of rendering with each state.
