blender-xatlas

I'm so sorry. This is not good. I have no idea what I'm doing.

This is a rough add-on for Blender allowing you to use Xatlas to unwrap and pack your uvs
It currently works on Windows/Linux (Tested on Windows 10, Windows 8, Ubuntu)
Code in /xatlas_src is modified from xatlas

Usage

Install

1. Add ./addons/blender-xatlas to you Blender addons folder, or download the .zip in releases and install in Blender [Preferences -> Add-ons -> Install... ]
2. Once enabled it will appear under the Xatlas option in 3D View sidebar (Default open with 'n')

Use

Warning! The tool will make a single user copy and triangulate your mesh (Unless using 'Pack Only') <img src="./readme_images/tool-location.png" alt="Tool Location" width="569" height="408">

1. Make sure your file is saved
2. Change your settings under Xatlas Tools
3. Select the objects you wish to unwrap and unpack
4. Click Run Xatlas
5. Wait for an undetermined period
6. Hopefully your unwrapped uvs should appear
