The options are as follows:
Option name | Data type | Description |
PowerOfTwo | int | The desired size of the heightfield, expressed as a power of two. See table in comments for equivalent sizes in pixels. |
HorizScale | float | The desired horizontal spacing between map pixels, in metres. |
Roughness | float | The noise octave amplitude propagation coefficient. A value of ~0.5 is typical. Larger values give rougher terrain. |
WrapFlag | bool | A flag for whether the map's north/south and east/west borders should tile seamlessly with one another. |
