GTA V add on/ replace vehicle creation HELP
So I am looking to start making my own gta 5 cars and modifying other peoples (for personal use only)
But I dont really know where to go to from there. I have zmodeler but I don't really know what else to do. Also is there a way to "unlock" cars? it wont let me import some cars into zmoldeler unless it says unlocked on the download site. is there a away to get around that?
