## What it is
A Unity technique and sample project from Unity Technologies for instancing SkinnedMeshRenderer characters to improve CPU/GPU performance in scenes with many animated characters. It supports root motion, attachments, LOD, culling, and mobile platforms (Unity 5.4+).

## Use cases
- render hundreds of animated characters efficiently in Unity
- optimize crowd scenes with skinned meshes
- instance SkinnedMeshRenderers with GPU instancing
- reduce CPU cost of character animation in large scenes
- add LOD and culling to instanced characters
- support root motion on instanced characters
- optimize character rendering on mobile

## When to choose
- you need many animated humanoid or skinned characters in a Unity scene
- performance of SkinnedMeshRenderer is a bottleneck
- you need root motion, attachments, or LOD with instanced characters
- targeting mobile platforms with crowds

## When to avoid
- you use a game engine other than Unity
- you only have a handful of characters (standard animation is simpler)
- you need actively maintained, fully supported production code (repo is in maintenance mode)
- you need non-skinned static mesh instancing (use standard GPU instancing)
