Custom Biome Preset

A palette shared by several biomes. A definition points at a preset and overrides only what differs.

Without it, a family of biomes that share an atmosphere — the same fog, the same sky, the same star brightness — has to repeat every value, and changing the mood means editing each one by hand.

Fields

A preset carries the same colour and visual attribute fields as a definition, and nothing else: no id, no base biome, no climate. It describes a look, not a biome.

Colours — fogColor, skyColor, waterColor, waterFogColor, grassColor, foliageColor, dryFoliageColor, sunriseSunsetColor, cloudColor, skyLightColor.

Visual attributes — fogStartDistance, fogEndDistance, skyFogEndDistance, waterFogStartDistance, waterFogEndDistance, cloudFogEndDistance, cloudHeight, skyLightFactor, sunAngle, moonAngle, starAngle, starBrightness, moonPhase.

See Custom Biome Definition for what each one does and its accepted range.

Precedence

For every field, in order:

1. the value set on the definition, if any;
2. otherwise the value from the preset, if one is set;
3. otherwise the value from the base biome.

A definition can therefore adopt an atmosphere wholesale and still diverge on one detail.

Example

A spectral night shared by several biomes:

skyColor:         #1A0B2E
fogColor:         #2D1B45
cloudColor:       #3D2A5A
skyLightColor:    #6B4A9A
fogStartDistance: 8.0
fogEndDistance:   96.0
skyLightFactor:   0.55
starBrightness:   1.0
moonPhase:        full_moon

A corrupted forest and a haunted swamp can both point at it, each keeping its own grass and water colours. Changing the fog once changes it for both.
