The tyRateOfChange float controller is a controller that can be assigned to any animatable float value. Its purpose is to provide an easy and procedural way to assign keyless linear animation to a float.
If you’ve ever wanted a particular float value to change steadily over time (ex: Noise texmap phase parameter) without having to worry about setting keyframes on it, the tyRateOfChange controller is an easy way to do it.
Rate of change: the rate at which the float value will change over time.
Ref. frame: the reference frame from which changes will begin to occur.
Value offset: an overall offset that will be applied to the resulting float value.
Per frame/second: the unit of time in which the rate of change will be calculated.
Clamp value: controls whether the final value will be clamped within a min/max range.
Min/max: the min/max range in which the final value will be clamped.
