Author how each time of day and weather looks — ambient colors, night darkness, and weather particles.

Atmosphere & Lighting

Your world already runs a day/night cycle and weather. Atmosphere is where you decide how they look — how dark night gets, what color dusk is, how heavy the rain falls. Set it once and it applies everywhere: the game client and the map-editor's night preview both read these exact values, so what you preview is what players see.

Find it in World Config → Atmosphere, next to Weather & Time.

> Nothing to set up to get started. Left untouched, the engine defaults give a deep-blue > night, a cool dusk, and neutral daylight — a good look out of the box. Every field below is > an override; anything you don't touch keeps its default.

Day / Night Ambient

The world tints the whole scene by a single ambient color per phase, and blends smoothly between them as the clock moves. Think of it as a colored multiply over the world: **white = full daylight** (no change), and darker, tinted colors darken and color everything.

1. Open World Config → Atmosphere. 2. Under Day / Night Ambient, click the color swatch next to a phase. 3. Pick a color. The preview bar shows a sample of grassy ground as it will look under that ambient, so you can judge the darkening at a glance. 4. Save. Connected players see the change immediately.

Phase	What it controls
Dawn	First light — usually a dim, cool-warm tint
Morning	Early daylight, faintly warm
Noon	Brightest — leave white for true daylight
Afternoon	Softer, golden light
Dusk	Fading light before night
Night	The dark hours — the default deep blue is `#2d2d50`

Night intensity (master darkness) scales all the darkening at once without touching each phase: 0× never darkens (permanent day feel), 1× is exactly what you set above, 2× is twice as dark. Use it to dial the whole cycle moodier or brighter in one move.

Reset on any phase drops just that phase back to its default.
Reset all to defaults clears every atmosphere override in one click.

Weather Looks

Every weather type has a full editor: pick a weather pill under Weather Looks and tune everything about how it renders. All nine weathers are editable — Cloudy gets drifting cloud shadows, Heatwave gets heat shimmer, and the precipitation types get falling particles that actually land on the ground.

1. Under Weather Looks, click the weather you want to change (a dot marks weathers you've customized). 2. Tune the groups below. Anything you don't touch keeps the engine default. 3. Save. Connected players see the new look immediately.

Particles

Field	What it does
Color	Tint of the rain streaks / snowflakes / sand grains
Opacity	Per-particle alpha (0 = invisible, 1 = solid)
Density	Multiplier on particle count (`0×` = none, `1×` = default, `2×` = double)
Size (px)	Base particle size — nearby drops are drawn larger
Fall speed	How fast the contact layer falls (px/s)
Flutter	Sideways wobble 0–1 — snow flutters, rain doesn't
Depth	How many background curtains render behind the near layer
Particle texture	Your own image (small, transparent, e.g. 32×32) — leave on Engine default for the built-in art

Wind

One global wind drives everything — particles, fog banks, cloud shadows.

Field	What it does
Direction	Screen degrees: 0° blows right, 90° straight down
Speed	Base wind speed (px/s)
Gustiness	0 = steady; higher = the wind surges and lulls
Wind follow	How strongly this weather's particles are driven by it

Ground

Rain splashes where it lands and leaves the ground wet (darker, with a faint sheen); snow accumulates into a cover that builds while it snows and melts after. Water never takes cover. To keep other terrain clear too (roads, lava, glass floors), add its tileset under World → Atmosphere → Ground Cover Exclusions — excluded terrain stays bare in every weather, and removing it from the list lets it accumulate again.

Anything that walks — players, NPCs, mobs, pets, mounts — leaves **footprints and trails** through snow cover and wet ground, so paths emerge where people actually travel. While the weather continues, fresh fall slowly fills old tracks back in; once it clears, prints stay until the cover melts. Trails appear on medium weather quality and above.

Field	What it does
Impact splash	Ripple ring (rain), dust puff (sand), or none
Splash texture	Custom impact art (e.g. a 64×64 ring with transparency)
Leaves on the ground	Nothing / wet ground / snow cover
Build-up time	Seconds of weather until the ground is fully covered
Melt / dry time	Seconds for the cover to fade once the weather ends
Cover tint / texture	Color and (optional) tiling texture of the cover — e.g. a 128×128 snow grain

Fog & Haze

Fog is layered scrolling banks at different depths, not a flat wash. Blizzard and sandstorm reuse the same machinery as a driven haze.

Field	What it does
Fog bands	How many banks render (0–4)
Bank size	Scale of the banks — bigger reads as broader, softer fog
Drift	How strongly the banks follow the wind
Fog texture	A seamlessly tiling noise/cloud image (e.g. 256×256)

Storm

Field	What it does
Lightning strikes	Two-stage flashes with distance-delayed thunder
Min / max gap	Seconds between strikes (strikes come faster at high intensity)
Flash color	The stroke tint

Sky & Wash

Field	What it does
Cloud shadows	Drifting dark patches on the ground (what makes Cloudy cloudy)
Heat shimmer	Air-wobble distortion near the ground (Heatwave)
Night response	How much night darkens the sky layers — snow stays bright, rain doesn't
Wash + strength	A full-screen color veil (fog grey, sandstorm tan)
Darkening	Extra darkness on top of time of day — storms dim midday

Gotchas

**Day/night ambient needs the Day/Night Cycle feature

flag on** to actually change over time. With it off, the world sits at whatever fixed time you set in Weather & Time — your ambient still applies to that time, it just won't move.

Weather looks need the Weather feature flag on. With it off there's no weather to

color.

Custom textures fall back gracefully. While a texture loads (or if it fails), the

engine's procedural art renders — the weather never blanks out.

Players choose a weather quality tier in Settings → Weather (Auto follows their

lighting tier). Low-end devices see fewer particles and skip cloud shadows / shimmer, but the wash and lightning always show — a storm still reads as a storm.

Changes apply on Save. Connected players update live; a player who is mid-load picks the

new values up on spawn. In the map editor, the night/dusk preview uses these values too.

White noon is intentional. If noon looks tinted, you likely set a non-white color there —

reset it for true daylight.

Interiors hide weather (maps marked interior show none), and ten seconds indoors won't

melt the snow outside — cover picks back up where it was when the player steps out.

Shadows have their own section further down the same tab. See

Shadows.
