Fast UV island packing add-on for Blender.

The add-on is located in UV/Image editor Tools tab under Shotpacker.

Island iterations determines how many vertical and horizontal locations are tried for each island in the packing algorithm. For example if this value is 100, then different locations tried for the island is 100 times 100 = 10000.

Rotation is rotation step. 0 is no rotation. 90 preserves texel orientation. For example 20 rotation means the island is rotated to 360/20=18 different positions at every checkpoint. 20 rotation also increases the running time 18x.

Mirror allows or disallows mirroring the island over an axis.

Margin how many pixels of free space island will have around itself. Distance between two islands is twice the margin. If the island size changes drastically during the packing, the margin can also change drastically, as it’s measured at the start of the packing process. If you want more accurate margins, pack multiple times.

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.
