## What it is
A Blender plugin that automates importing, fixing, and optimizing 3D models for VRChat, supporting formats like MMD, XNALara, Mixamo, and DAZ/Poser. It compresses hours of manual model preparation into one-click operations like decimation, eye tracking, lip sync, and texture atlas creation.

## Use cases
- import mmd models into vrchat
- optimize blender models for vrchat upload
- create eye tracking and lip sync for avatars
- decimate 3d model meshes while keeping shapekeys
- translate japanese bone and shape key names
- create texture atlas for blender model
- convert mixamo or xnalara models to vrchat avatars

## When to choose
- you prepare VRChat avatars from MMD, Mixamo, XNALara, or DAZ models
- you want one-click model fixing, decimation, or bone merging in Blender
- you need automatic eye tracking, lip sync, or dynamic bone setup

## When to avoid
- you work outside Blender or target platforms other than VRChat
- you need fine-grained manual control over every rigging step
- you use Blender versions far newer than the plugin supports
