Stratus Volumetric Clouds

Stratus Volumetric Clouds brings realtime, ray-marched volumetric
clouds and a complete physical atmosphere to the Universal Render
Pipeline — 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-FRIENDLY
Because it's a complete sky, it fits any outdoor game or
visualization: open worlds, flight & drone sims, racing,
exploration/adventure, RPGs, and architectural or environment
visualization. No genre-specific content is required — everything
adapts to your scene's lighting and art direction.

INCLUDED
Demo scene, weather / noise / blue-noise textures, sample meshes
(Stanford bunny, zombunny), prefabs, and materials.

COMPATIBILITY
URP 14.x (Unity 2022.2+) and Unity 6 (Render Graph). No third-party
dependencies.
