Clamp Max[-∞..+∞]

Various settings related to shader output are located here. Scale the values overall with  Minand Max. The curvature shader can output values greater than one. You can clamp the values between Clamp Min and Clamp Max with the Clamp Enable option. The Clamp Expand option will stretch the values back to 0-1 after clamping.
