Okay okay, they're not REALLY pants, they're just a recolor, but still. I had the material for his "pants" backed up, and since there was interest in him having his pants again, here it is! Also, I tested to make absolutely sure, this does work perfectly fine regardless of whether you're on a server or not!
All you need to do is copy the file to your pvkii\custom folder. Please note, that if this folder doesn't exist, you can create the folder. Just make sure that it's called "custom" without the quotes of course.
Unless you installed Steam to a custom place like I have, it will by default be in "C:\Program Files (x86)\Steam" or if you don't have that, "C:\Program Files\Steam." Don't worry about those CACHE files, they are auto-created when you run the game.
Also, please note that if you are running from a completely fresh install of Pirates, Vikings, and Knights II, it may be in "Steam\SteamApps\common\pirates, vikings, and knights ii"
