hbmspace:noise_caves

Noise caves replacing the aquifer.

Put the function inline as noise_router.barrier of the noise settings with aquifers_enabled: false; a reference to a density-function file there is ignored. A cell with positive density is solid; otherwise it is air where caves is negative, including below sea level, and the level's fluid elsewhere.

Fields

FieldMeaning and default
typehbmspace:noise_caves.
cavesDensity function; negative values are caves.

Example

Abridged, from data/hbmspace/worldgen/noise_settings/mun.json:

{"type": "hbmspace:noise_caves", "caves": "…"}
