It will register under the map selection screen in the game and everything? Cool. Oh and I have another question, I also downloaded character models but I dont know how to install that either any help please?
Model "installs" are basically the same, you just replace files that are already there. Go to \esf\models\player, copy your downloaded model into the right folder, and give it the same name as the one(s) in there had before. They're called by name, so make sure it's exact.
Just make sure you backup your old/default files, incase the ones you downloaded don't work, or you want to switch back.
