Instance Property


A number between 0.0 and 1.0 that modulates the effect of the material property. Animatable.


@property(nonatomic) CGFloat intensity;


The default intensity is 1.0. Reducing the intensity fades out the contents of the material property, causing different effects depending on which visual property of an SCNMaterial object it represents:

  • For the normal property, intensity varies the apparent roughness of the normal-mapped surface. Reducing intensity makes the surface appear more smooth.

  • For the multiply property, reducing intensity blends the material property’s colors with white, effectively reducing the strength of the color multiplication effect.

  • For all other properties, reducing intensity dims the material property’s contents.

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