An offset to add to the input value of the controller’s animation.
Mac Catalyst 13.0+Beta
Use this property and the inputScale property to pre-process input values to the controller’s animation. For example, if you use the SCNParticleInputModeOverDistance option to animate a particle’s opacity as a function of its distance from a specified point, a bias specifies the minimum distance at which the animation’s fromValue property or first keyframe value takes effect.
The default value is 0.0, leaving the input value to the animation unchanged. The range of possible values depends on the controller’s animation.
A particle property that provides input values for this property controller’s animation.
