URP Volumetric Lighting System

Bring your Unity 6 URP scenes to life with four fully integrated, compute-shader powered volumetric effects — all controllable directly from the Post Process Volume.

✨ What’s Included

• Volumetric Lighting — Screen-space raymarched light scattering with tint, intensity, and scatter controls. Zero scene setup required.
• Volumetric Fog — 3D texture fog with placeable FogVolume zones. Supports colour, density, wind drift, and noise-based wisps.
• Volumetric Clouds — Fully raymarched cloud layer with self-shadowing, animated wind, coverage, and scattering. Renders at any altitude.
• Volumetric Explosions — Runtime-spawned volumetric explosions with custom radius, colour, and auto-fadeout. Up to 64 simultaneous blasts.

🔧 Easy Integration

Drop in three prefabs —  LightingManager ,  FogVolume , and  Global Volume  — and you’re rendering in minutes. All visual parameters are exposed through standard Post Process Volume overrides, so everything works with your existing volume blending and layer setup.

⚡ Performance First

Every system is built around compute shaders and 3D density textures. Raymarch sample counts are fully adjustable so you can dial in the quality-performance balance for any target platform. Both render passes automatically skip Preview and Reflection cameras.

📋 Requirements

• Unity 6+ with Universal Render Pipeline
• Render Graph enabled
• GPU with compute shader support
• Depth Texture enabled on URP Pipeline Asset
