Use this property and the
input property to pre-process input values to the controller’s animation. For example, you use the
SCNParticle option to animate a particle’s opacity as a function of its distance from a specified point, a scale specifies the range of distances over which the animation takes effect.
The default value is
1, leaving the input value to the animation unchanged. The range of possible values depends on the controller’s animation.
