Description
Fast UV island packing add-on for Blender.

Additional information can be found at: http://blenderartists.org/forum/showthread.php?420127-Addon-UV-packing

Installation
Use "Install Add-on from File..." in Blender User Preferences/Add-ons and navigate to the downloaded zip-file. Then turn it on in the add-ons tab.

Newer versions (Blender 2.80+) require installation of libraries, by pressing the button in the addon settings, after which you need to restart Blender.

Note: For MacOS, only unsigned versions of Blender 2.80 will work (pre-2.80 RC1 and all custom builds). Versions that are signed will not work (official blender.org releases RC1+).

Uninstall/update
Start/restart Blender and remove the addon by pressing the remove button in Preferences/Add-ons/Shotpacker.

Requirements
Working internet connection.
Recent 64-bit system; Windows, MacOS, Ubuntu Linux.
If the UV islands have a lot of broken self overlapping geometry, the results are undefined. It's best to clean up the mesh before running packing. Sometimes Smart UV makes weird UV, and causes errors in Shotpacker, which can be fixed by running the Blender default internal packing algorithm first.
