Licence
What you may do with the skins you buy. The same terms are in LICENSE.txt in every order.
Two kinds of licence
A server licence covers one DayZ server, named by its IP and game port, and every player on it. A player licence covers one player, named by their Steam64, on any server whose owner installs it for them.
On a server running LBmaster's SkinSystem, the files in a player licence apply the skins to that player only. Elsewhere nothing in the game enforces it, so the licence does: if a server gives the skins to more than the licensed player, it needs a server licence.
You may
- install the files on the licensed server, or on a server where the licensed player plays;
- give the mod folder to that server's players as part of its client mods, so they can see the skins there.
You may not
- resell, share or publish the files, or include them in a modpack offered to other servers;
- change the textures and pass them off as your own, or remove the licence;
- use the skins on a server, or for a player, other than the one named in the licence;
- under a player licence, give the skins to players other than the one named in it.
Cosmetic only
The skins change how an item looks and nothing else. If you run a monetised server, Bohemia Interactive's monetisation rules apply to how you offer them to your players.
