الوسائط 1 للقائمة Dynamic Time of Day & Weather — Physically Based Sky System

الوصف

One actor. A complete, believable sky.

Drop a single Time of Day actor into your level and get a full, physically based sky in seconds — sun, moon, atmosphere, volumetric clouds, real-time sky light, height fog, and post-processing, all driven together from a real-world solar model. No blueprint wiring, no fragile setup: place it, pick a time, and go.

Physically based sun & moon

The sun and moon positions come from a real NOAA solar-position model driven by your time, date, latitude, longitude and time zone — so shadows, sunrise/sunset and the arc of the day track the real world. Lighting uses measured real-world values: ~120,000 lux clear-sky noon, warm ~2000 K sunrise blending to neutral ~6500 K midday, and a cool moonlit night.

Drives your whole sky, together

☀️ Directional sun light (+ optional moon light, second atmosphere sun)
🌤️ Sky Atmosphere
☁️ Volumetric Clouds
💡 Real-Time Capture Sky Light
🌫️ Exponential Height Fog (with volumetric fog)
🎞️ Global Post Process — saturation & exposure

Dynamic weather

Five presets — Clear Sky, Medium Clouds, Cloudy, Overcast, Storm — that smoothly blend cloud coverage and density, dim the sun, lift ambient light, and thicken height + volumetric fog. Enable random weather with per-preset probability weights, a randomized change interval, and a change-chance control for natural, unpredictable conditions. (Rain-ready — designed to extend on top of Storm.)

Night sky

A camera-following starfield and a textured moon that rise opposite the sun and fade in at dusk — with brightness and size controls.

Believable exposure
Built-in exposure control solves the classic "night looks like daytime" auto-exposure problem, keeping nights dark and days bright with tunable EV range and night darkening.

Made for iteration

🕹️ Dockable editor control panel: time slider, animate toggle, day-length (speed), weather selector, random-weather controls, and GI method — all in one place.
▶️ Time and weather animate live in the editor (no need to toggle viewport realtime) and in play.
🌐 Global Illumination selector (Lumen / Screen Space / None / Plugin) — set it to Plugin for compatibility with voxel/GI plugins.
🧩 Full Blueprint API: set time, weather, day length, animate, and read sun elevation.
