## What it is
MaterialX is an open standard and C++/Python library for representing and exchanging rich material and look-development content across computer graphics applications and renderers. It includes shader generation, a viewer, and a graph editor, and is hosted by the Academy Software Foundation.

## Use cases
- exchange material definitions between DCC tools and renderers
- generate GLSL shaders from material graphs
- author and preview PBR materials in real time
- port look-development setups across film and game pipelines
- build tools that read or write MaterialX documents

## When to choose
- you need a vendor-neutral standard for shading networks and materials
- you work in VFX, animation, or real-time rendering pipelines
- you want shader generation from portable material graphs

## When to avoid
- you need general-purpose 3D modeling or scene exchange rather than materials
- your toolchain has no MaterialX support and you cannot add it

## Facets
- artifact type: library
- maturity: stable
- function: graphics, sdk, parser, templating
- domain: graphics, simulation
- platform: cpp, python, cross-platform
- tags: materialx, shading, look-development, rendering, vfx, open-standard, shader-generation, pbr, game-development, gpu
