I'm recording a few videos with mods I have, one of them is AWS.

I normally use *.lang files in my resource pack to localize or customize names of objects in the game. But the skins are different, they are stored outside the mod directory.

Sorry no way to do that because the players make the names. Best I can suggest is to save them with a new name in the armourer, I will maybe allow them to be renamed in the anvil.
