Realtime volumetric clouds for URP — sculpt clouds from any mesh, paint wind & coverage directly in the Scene view, and get a full physical sky with light shafts, all in one easy-to-use system.Stratus Volumetric Clouds brings realtime, ray-marched volumetricclouds and a complete physical atmosphere to the Universal RenderPipeline — with tools that let you shape clouds the way you want,in minutes.WHAT YOU GET- Realtime volumetric clouds rendered with volumetric raymarching, shape & detail 3D noise, and self-shadowing.- A physical atmosphere: Rayleigh + Mie atmospheric scattering, procedural skybox, sun disk, and volumetric light shafts (god rays).- A day/night sun controller that automatically drives directional light color and scene ambient light.FULLY CUSTOMIZABLE- Sculpt clouds from any mesh: the built-in Mesh → Texture3D baker turns any 3D model into a cloud shape (Surface Shell or SDF modes).- Paint directly in the Scene view: the Flowmap Painter sets wind direction & speed, the ShapeMap Painter sets cloud coverage and shape.- Every visual is tunable: cloud density & threshold, top/bottom softness and roundness, ambient gradient, wind speed, and noise evolution.- One-click presets — Cumulus, Stratus, Cumulonimbus — plus High/Low quality presets and adjustable ray steps to hit any performance target.GENRE-FRIENDLYBecause it's a complete sky, it fits any outdoor game orvisualization: open worlds, flight & drone sims, racing,exploration/adventure, RPGs, and architectural or environmentvisualization. No genre-specific content is required — everythingadapts to your scene's lighting and art direction.INCLUDEDDemo scene, weather / noise / blue-noise textures, sample meshes(Stanford bunny, zombunny), prefabs, and materials.COMPATIBILITYURP 14.x (Unity 2022.2+) and Unity 6 (Render Graph). No third-partydependencies.Technical Details- Supported Unity Versions: Unity 2022.2 and newer (tested on Unity 2022.3.34f1 LTS). Unity 6 is fully supported via the Render Graph code path.- Render Pipeline: Universal Render Pipeline (URP) only — URP 14.x and URP 17.x (Unity 6). Not compatible with the Built-in Render Pipeline or HDRP.- Dependencies: com.unity.render-pipelines.universal (URP). No third-party assets required.- Supported Platforms: Windows, macOS, Linux (Standalone). Requires compute shader support (DirectX 11+, Vulkan, Metal). WebGL is not supported.- Performance: Adjustable raymarch steps (up to 120) and light steps for cloud self-shadowing. High / Low quality presets switch the internal cloud resolution between 1024 and 512. Settings can be tuned per scene for any target hardware.- Setup: Add the AtmosphericScatteringFeature renderer feature to the URP renderer and attach the CloudSystem component to a GameObject with a Directional Light assigned. The render pass requests the camera depth texture automatically.- Integration: Cloud, noise, wind and coverage settings are exposed on the CloudSystem component (live in the Scene and Game views). Atmospheric scattering and light shafts are driven by Unity Volume profiles.- Editor Tools Included: • Mesh → Texture3D baker — bake any mesh into a cloud shape volume (Surface Shell / SDF modes) • Flowmap Painter — paint wind direction & speed in the Scene view • ShapeMap Painter — paint cloud coverage / shape in the Scene view- Package Contents: • C# scripts & render passes (CloudSystem, SunController, AtmosphericScattering Volume) • Shaders & compute shaders (atmospheric scattering, volumetric clouds, light shafts, procedural skybox) • Demo scene with mountain terrain • Textures (weather maps, shape/detail noise, blue noise) • Sample meshes (Stanford bunny / zombunny), prefabs, materials
