cumulus_default

Default weather preset for VolumetricSky.component. Captures the v4-tuned cumulus look: visible discrete clouds, warm-afternoon sun, moderate coverage.

Use

local sky = entity.spawn("sky")
sky.component.add("VolumetricSky", {})
preset.apply("cumulus_default", { entity = sky.id, component = "VolumetricSky" })

The values set the component's preset Field.table as a unit — one Sync replication carries every shaping/lighting parameter to peers. Tweak by reading the values and changing them before the component is added:

local values = preset.values("cumulus_default")
values.shaderVariant = "v5"        -- swap raymarcher
values.preset.coverage = 0.6       -- sparser sky
sky.component.add("VolumetricSky", values)

Authoring more presets

Capture a sky you have tuned with preset.capture({ entity = sky.id, component = "VolumetricSky" }, "<name>"), or drop another <name>.preset/ folder next to this one (or anywhere under /zero/source/); the asset indexer registers it and preset.values("<name>") resolves it. Common alternatives:

• stratocumulus.preset — broad overcast layer (coverage ~= 0.15, cloudType = 0.5, altitudeHigh ~= 0.65).
• clear.preset — barely any cloud (coverage ~= 0.7, densityGain ~= 0.2).
• storm.preset — dense black anvils (coverage ~= 0.1, densityGain ~= 0.85, sunColor ~= [0.6, 0.55, 0.5]).

preset is one Field.table: applying a preset replaces it whole, so provide every field.
