Instance Property


The distance from the floor at which scene contents are reflected at full intensity. Animatable.


@property(nonatomic) CGFloat reflectionFalloffStart;


SceneKit can render reflections on a floor using an opacity gradient (or falloff). With this gradient, the reflections of scene contents closer to the floor are more visible than those of scene contents farther from it. This property marks the distance at which the opacity gradient begins. Scene contents closer to the floor than this distance appear in the reflection with full intensity.

The default value of this property is 0.0, indicating that the falloff gradient begins immediately.

You can animate changes to this property’s value. See Animating SceneKit Content.
