Low-poly clouds. Volumetric lighting. Dynamic weather.

RADIANT is a real-time sky and cloud rendering system built around physically based light. Bring together atmospheric skies, softly lit low-poly clouds, cirrus accents and connected weather in Unreal Engine 5, Unity HDRP and WebGPU.

What’s in the box

  • Sky & cloud assets: 28 original cloud models with 3 additional LODs each, high-altitude cirrus, dynamic sun and moon, 94,250 catalog stars and a procedural Milky Way.

  • Lighting & weather effects: Volumetric cloud lighting, shadows, god rays, local rain and lightning.

  • Weather & time of day: A full day/night cycle, fixed conditions, seeded automatic weather and timed forecasts with gradual transitions.

  • Art direction: Editable profiles, authored cloud arrangements and 98 controls to shape your sky.

Built for real-time rendering

Fixed cloud and sun positions let RADIANT reuse its lighting cache. As the sky changes, cache updates are spread across frames to distribute the work.

Work through Unreal Details/Blueprint/C++ or Unity Inspector/C#. Your project controls exposure and tone mapping; an optional example look is included.

Technical details

  • Unreal modules: 2 (Runtime and Editor).

  • C++ classes: 60 implementation classes, plus 10 automated-test classes.

  • Blueprints: 3 in the example project; the core plugin is C++.

  • Verified Unreal configurations: 5.8.2 / Windows / D3D12 SM6; 5.7.0 / Linux / Vulkan SM6.

  • Verified Unity configurations: 6000.6.0f1 / HDRP 17.6 on Windows; 6000.5.2f1 / HDRP 17.5 on Linux.

  • Dependencies: Unreal's bundled ProceduralMeshComponent; Unity HDRP, with Input System for the example; a hardware WebGPU-capable desktop browser for WebGPU.

  • Network replicated: No. Connect weather to your game's synchronization, surface wetness, splash and audio systems as needed.

One purchase, all platforms. Lifetime updates.

Includes Unreal Engine 5, Unity HDRP and WebGPU versions, source code and offline integration documentation. Start with the Basin Observatory demonstration scene and its 13-chapter rendering tour, then make the sky your own.
