## What it is
AutoLOD is a Unity framework that automatically generates levels of detail (LOD) for 3D model assets on import and optimizes whole scenes via hierarchical SceneLOD chunking. It supports pluggable mesh simplifiers such as UnityMeshSimplifier, Simplygon, and InstaLOD.

## Use cases
- automatically generate LODs for 3D models in Unity
- simplify meshes on import to improve game performance
- chunk large scenes into hierarchical LODs
- swap in custom mesh simplification backends per model
- generate texture atlases automatically
- optimize draw distance and rendering cost in large Unity scenes

## When to choose
- you use Unity and want automatic LOD generation without manual mesh work
- you need a pluggable framework to integrate Simplygon or InstaLOD
- you want hierarchical scene-level LOD for large environments

## When to avoid
- you need officially supported, production-stable tooling (it is explicitly experimental)
- you work outside the Unity engine
- you require guaranteed upgrade paths between releases

## Facets
- artifact type: plugin
- maturity: experimental
- function: graphics, simulation, developer-tools
- domain: graphics, performance
- platform: game-engine, cross-platform
- tags: unity, level-of-detail, lod, mesh-simplification, scene-optimization, 3d-graphics, game-development
