The Threshold node lets you alter the terrain based on the height limit specified. It can especially useful when converting a soft mask to a hard mask.
Properties
| Threshold | |
| Level | Specifies the threshold value used to separate terrain features. Values above this level are retained, while values below are discarded or set to a minimum. Adjusting the level controls the cutoff point for terrain masking or feature isolation. |
