## What it is
The official Khronos Group glTF 2.0 importer and exporter addon for Blender, written in Python. It enables round-trip conversion of 3D scenes, meshes, animations, and textures between Blender and the glTF format, and is bundled with Blender 2.80+.

## Use cases
- export blender models to gltf for web viewers
- import gltf files into blender
- prepare 3d assets for game engines
- convert blender scenes to gltf 2.0
- round-trip gltf files preserving animations and materials

## When to choose
- you need reliable, standards-compliant glTF 2.0 I/O in Blender
- you want the official Khronos-maintained importer/exporter
- you need round-trip workflows with shared import/export code

## When to avoid
- you need glTF support outside Blender
- you use Blender 2.79 without the legacy release
- you need exporters for other 3D formats like FBX or OBJ

## Facets
- artifact type: plugin
- maturity: active
- function: file-system, serialization, graphics
- domain: graphics, cross-platform
- platform: python, cross-platform
- tags: blender-addon, gltf, 3d-models, import-export, khronos, game-development, desktop
