Smooth Step Node
Calculates a smooth Hermite interpolation value between 0 and 1, if input value is in the [ Min , Max ] range. Assuming that Max value is greater than Min, a value of 0 is returned if input is less than Min. On the other hand if input is greater than Max than a value of 1 is returned.
Smooth Step for multi-component data types is applied per-component. If Min and Max have different numbers of components a cast is performed to match the one with the greater number of components.
Simply put, this node converts a linear input gradient to an S-type gradient.
