A bunch of the ships in this faction pack I've never posted on the workshop, but are available in this mod. Here's how to take those designs:

1 - Go to D:\Steam\steamapps\workshop\content\445220\2005799455, in this folder are all of the ship xml files.

2 - Copy all / desired xml files. Be warned, some of the files are not named correctly.

3 - Go to AppData\Roaming\Avorion\ships, and make a new folder

4 - Paste the xml's into that new folder

5 - Enjoy!
