If you want to make a Map or Mod Pack that gives AW skins to players in some way read this.
Here is a short explanation of how the mod works.
When a skin is loaded from the library or created with the armourer, the mod will give it a unique ID then save it into the skin-database folder in the world folder with the ID as the file name. The mod will then create a new equipment skin item in the library or armourer and add the skin ID onto the items NBT data. When a client tries to render the skin it gets the ID from the items NBT and checks if it has the model, if not it will request the model for that skin ID from the server. When the server get a request for a model it will check for a matching file name in the skin-database folder and send it back to the client. The same process is used for skinning weapons and armour an ID number is added to the items NBT so the mod knows what model to render.
I hope that explanation was not too technical.
So in short if you create an skin in one world then somehow copy that item into another world without using the library, it will not work unless the skin-database folder is also copied to that world.
If you have a pre-made world for players to play on then this is not really an issue as the skin-database folder will already be in the world folder.
If you are allowing players to make their own world but want to give skinned items with something like HQM, the skin-database folder from the world that you setup the HQM quest rewards will need to be copied into the players new world. AW can actually do this, you just need to make a folder inside your instance folder called "equipment-database" and copy the contents of the skin-database folder into it. When the player creates a new world all the files in equipment-database folder will be copied into the worlds skin-database folder, This only happens when the world is first created.

+1 Me and my friends have been using this mod for awhile now, can't have a proper modded server without it. You have no idea how long I wanted a mod like this, then I happen to somehow stumble across this masterpiece. Everyone should have this mod, everyone. (me in the centre with the pumpkin head :D)
