Metaplanets Creator: Atmospheres

Metaplanets Creator: Atmospheres adds a multi-atmosphere system to Unreal Engine 5, created to closely align with the default Sky Atmosphere plugin while designed for scenes where multiple planetary bodies may exist.

Features:

Physically accurate skies for any planet — and more than one planet in the same scene.

• Unlimited planets, one sky system. Stack as many atmospheres as you like in a single level; near planets correctly haze over distant ones, so multi-planet and solar-system scenes just work.

• Tune any world from Earth to alien. Sky color, haze thickness, sunsets, ozone tint — every atmosphere gets its own fully editable physical parameters with realistic Earth defaults.

• Real day/night and eclipses. Planets show a true day/night terminator from space; eclipses darken the sky, the light, and the clouds together, with a glowing refracted ring at totality.

• Your sun light, on autopilot. Let the atmosphere drive your directional light — the sun goes golden at dawn, red at dusk, and dims through night to a moon light that only wakes up after dark. Scene lighting always matches the sky.

• Multi-layer volumetric clouds. Stack cloud decks at different altitudes: cumulus, cirrus, storm systems, or smoke/ash/fog for alien worlds. Wind, coverage, storm structure, and rain shafts under the clouds — all editable, no authoring needed.

• Clouds that belong to your planet. Bind cloud layers to your planet's weather mask so skies match your authored climate. Reusable cloud presets let you share a look across planets and projects.

• Distances fade like real life. Terrain and clouds sink into atmospheric haze on the horizon — coherent, no popping, adjustable strength.

• Fast and game-ready. Two cloud quality modes (cinematic or performance), automatic temporal upscaling, and exposure that plays nicely with UE's auto-exposure.

• Large World Coordinates safe. Realistic planet sizes and orbital distances, no jitter or precision artifacts.

• Drop-in & Blueprint friendly. Place the actor, pick your settings — everything renders live in the editor. All parameters are Blueprint-driven for procedural and runtime worlds.

Each atmosphere is capable of having it's own cloud layers, which can be customized to your own liking. The volumetrics renderer is quite in-depth and allows for different rendering techniques such as froxels (as used in Red Dead Redemption 2).

It's an exploratory plugin designed for use with Metaplanets Creator, we are very open to customization and feedback.
