## What it is
uRaymarching is a Unity asset that generates raymarching shaders from templates, letting developers create ray-marched objects by writing only a distance function. It supports Forward and Deferred legacy pipelines plus URP, VR, lighting, shadows, transparency, and depth-correct intersection with polygonal meshes.

## Use cases
- create raymarched 3D shapes in Unity by writing only a distance function
- generate Unity shaders from templates without writing boilerplate
- render procedural geometry that correctly occludes with polygon meshes
- add raymarching effects to VR or VRChat projects
- do full-screen raymarching post effects in Unity
- use lit, unlit, or transparent raymarching materials with shadows

## When to avoid
- you target HDRP, which is not yet supported
- you need a general-purpose shader editor rather than raymarching-specific templates
- you work outside Unity

## Facets
- artifact type: library
- maturity: maintenance
- function: graphics, simulation, plugin-system, developer-tools
- domain: graphics, simulation
- platform: cross-platform, windows
- tags: unity, raymarching, shader-generation, hlsl, distance-functions, vr, urp, shader-template, sdf, game-development, macos, gpu
