## What it is
Malt is a customizable real-time rendering framework for stylized non-photorealistic rendering (NPR), distributed as a Blender addon. It lets technical artists build fully custom Python render pipelines and GLSL shaders with a shadertoy-like workflow, including automatic node generation from GLSL functions.

## Use cases
- render stylized non-photorealistic animations in Blender
- create custom toon or illustration-style shading models
- write custom render pipelines in Python with GLSL shaders
- generate Blender nodes automatically from GLSL functions
- do line rendering and light groups for illustration workflows
- debug GPU rendering with RenderDoc inside Blender
- share custom shaders and pipelines as plugins with non-technical artists

## When to choose
- you need stylized NPR rendering beyond what EEVEE or Cycles offer
- you are a technical artist who wants code-first control over shaders and pipelines
- you want a shadertoy-like GLSL workflow integrated into Blender
- you need real-time rendering for animation and illustration

## When to avoid
- you only need photorealistic rendering
- you work on macOS (only Windows and Linux are supported)
- your GPU lacks OpenGL 4.5 support
- you want a turnkey renderer without writing or configuring shaders
