FlattenDirection

Remarks

Unreal's flatten tool has exactly this setting and it is worth copying literally: cutting a building pad into a hillside means Lower, and filling a dip in a road means Raise. Both does both and is what makes the shoulder of a cut pad also get filled, which is usually not what was meant.

Fields and properties (3)

• Both

  Whatever it takes to reach the target.

• Raise

  Only fill: samples already above the target are left alone.
