Parameters

• Position: 0.0 - 1.0Similar to a brightness control, shifts the midpoint of the result. When used on a gradient input, this expands and shrinks the transition point.
  Important: a default value of 0 means the end result is always black, so try starting with 0.5!
• Contrast: 0.0 - 1.0
  Adjusts the contrast of the result. Can be used to set the hardness of the transition.
• Invert Position: False/TrueInverts the final result.
