## What it is
A simple, easy-to-read toon lit shader example for Unity's Universal Render Pipeline (URP), intended as a shader coding tutorial. It demonstrates writing custom lit shaders in HLSL with outline support for character rendering.

## Use cases
- learn writing custom toon lit shaders in Unity URP
- add cel-shaded look to game characters
- implement outline rendering for characters
- study HLSL shader code examples for URP
- create anime-style character rendering in Unity

## When to choose
- you want a minimal, readable example to learn URP shader coding
- you need a simple toon shader with outlines for Unity characters
- you are learning HLSL within Unity's render pipeline

## When to avoid
- you need a production-ready full-featured toon shader suite (use NiloToonURP full version)
- you are not using Unity URP
- you need shaders for other engines like Unreal or Godot

## Facets
- artifact type: learning-resource
- maturity: active
- function: graphics, game-engine
- domain: graphics, tutorials
- platform: game-engine, cross-platform
- tags: unity, urp, toon-shader, hlsl, shader-tutorial, outline, cel-shading, game-development
