## What it is
A Unity plugin implementing volumetric shadows (light shafts / light scattering) for directional and spot lights. It uses adaptive raymarch sampling with interpolation to make the effect affordable in real-time rendering.

## Use cases
- add god rays to a Unity scene
- render volumetric shadows from spot lights
- create light scattering effects through stained glass
- optimize volumetric lighting performance in games
- simulate sunbeams through fog or dust

## When to choose
- you need light shafts in Unity 4.x-5.x
- you want a performance-conscious volumetric shadow implementation
- you target DX9/DX11 on Windows or OSX

## When to avoid
- you use modern Unity versions (2017+)
- you need a maintained, universally supported volumetrics solution
- you need directional light support in newer pipelines

## Facets
- artifact type: plugin
- maturity: abandoned
- function: graphics, image-processing, simulation
- domain: graphics
- platform: windows, game-engine
- tags: unity, volumetric-lighting, light-shafts, shaders, rendering, game-development, macos
