Generates a mask by evaluating the input map against the selected curve. Curve Mode defines how the input data should be interpreted:

• Normalized: Will first normalize the input data and apply a curve that goes from 0 to 1
• Global: It will treat the Input data directly as it comes
• Filter Curve: Curve used in Normalized mode.
• Global Filter Curve: Curve used in Global mode.

It can be used as a band pass, high pass, low pass or any combination of wave filters. The curve is evaluated such as that for an x (representing the height value of the input map) it returns a y (representing the equivalent within that curve).
