Download the appropriate default skin in-game.
Create a folder in the AH/skins folder.
Name it based on the default folder but add the next number up -
eg.
spit8 (default)
spit81 (1st offline skin)
spit82 (2nd offline skin)
lanc3 (default)
lanc31 (1st offline skin)
etc etc
Unzip the contents of the downloaded offline skin into the new folder.
NB If there is already skins available in-game for it look in the skins folder and find the last file listed for it -
eg. the last 190D-9 file listed is 190d99
Your first offline skin folder is one higher - 190d910
Last Ki84 file is Ki847 therefore your first offline skin would be folder Ki848
