The factor to be applied in the function operation specified in CurveType. Default value is 0.
This parameter is used only if CurveType is CurveType.Exponential, CurveType.Logarithmic or CurveType.Sigmoid. If CurveType.Exponential or CurveType.Sigmoid is selected its value can be any value (+/-). If CurveType.Logarithmic is selected its value should be >= 0. If Factor = 0, the lookup table will be filled linearly.
