## What it is
A large curated library of MatCap (Material Capture) textures in PNG and ZMT formats, organized by color, for use in 3D graphics. MatCaps bake lighting and reflections into a single texture, enabling cheap shadeless rendering in engines like Three.js, Blender, Unity, and ZBrush.

## Use cases
- find matcap textures for three.js webgl scenes
- download litsphere textures for zbrush sculpting
- add cheap stylized lighting to a 3d model without setting up lights
- non-photorealistic rendering textures for blender or unity
- browse matcap pngs by color for a game project

## When to choose
- you need ready-made matcap textures instead of authoring your own
- you want fast, lighting-free shading for sculpting or previews
- you work in three.js, blender, unity, or zbrush and need a variety of materials

## When to avoid
- you need physically-based lighting or dynamic environment reflections
- you need a code library rather than texture assets
- your camera rotates freely around objects, where matcaps look wrong

## Facets
- artifact type: dataset
- maturity: active
- function: graphics, image-processing
- domain: graphics, web-development
- platform: cross-platform, game-engine
- tags: matcap, textures, threejs, webgl, opengl, zbrush, blender, unity, non-photorealistic-rendering, shading, litsphere, png-textures, game-development, web
