## What it is
A pure C# Unity3D library for importing and exporting glTF 2.0 assets at both editor and runtime, with no native dependencies. It supports many glTF extensions, custom plugins and callbacks, and works across all Unity render pipelines (URP, Built-in, and partially HDRP) including WebGL.

## Use cases
- load glTF models at runtime in a Unity game
- export Unity scenes or animations to glTF 2.0
- import 3D assets in WebGL builds
- convert Unity materials and blend shapes to glTF
- extend glTF import/export with custom extensions
- record animations to glTF via GLTFRecorder

## When to choose
- you need runtime glTF loading in Unity on any platform including WebGL
- you want both import and export with extensible plugin support
- you use URP or Built-in render pipeline on Unity 2021.3+

## When to avoid
- you primarily use HDRP, whose support is not actively maintained
- you need a non-Unity engine or a native-code loader
- you only need static editor-time import and prefer a simpler tool

## Facets
- artifact type: library
