Introduction

What is Volumetric Lights 2?

Volumetric Lights 2 is a lightweight, high-performance volumetric lighting solution for Unity’s Universal Render Pipeline (URP). It adds realistic god-rays, light shafts, and atmospheric scattering to your scenes using an optimized ray-marching algorithm.

The asset supports spot, point, and area lights, with independent shadow maps, translucent shadow casting, dust particles, cookie textures, noise-driven animation, and direct light projection — all rendered in real time on desktop and mobile.

Key Features

• Optimized ray-marching with configurable quality presets
• Per-light shadow occlusion with baked or real-time shadow maps
• Translucent shadow maps — colored shadows through stained glass or transparent objects
• Direct light cast — illuminate opaque surfaces from the volumetric volume
• Cookie texture projection for spot lights
• 3D noise animation with configurable wind direction
• Dust particles rendered inside the light volume
• Global composition blur via a URP Render Feature for smooth blending
• Depth pre-pass Render Feature for transparency support
• Auto-toggle (LOD) — distance-based dimming and deactivation
• Profiles (ScriptableObjects) for saving and sharing light presets
• Full C# scripting API
