Valley Cut - Macro for World Machine

Gives your terrain valleys. Requires World Machine 3026 or above for normal version and World Machine 3016 or above for the legacy version (named Valley Cut by HYLK 3016).

Changelog

-- 1.2

• Added a Min Height and Min Height Falloff parameter, allowing to set the minimal height before valleys are cut and a falloff to create smoother transitions.
• Added a Steep Peaks parameter, giving you control over the steepness of the tops of the valleys. This is due to an unwanted result introduced in 1.1, when internal normalisation was introduced.

-- 1.1

• Removed an odd spike from the valley substraction.
• Valley Cut now normalises the terrain for it's masking, resulting in more a more generalised and predictable result.
• Made a WM 3016 and above compatible legacy version.
