Hello I have been toying around with GECK for about a month now. I've gone through the make your own vault tutorial, I've made some NPCs, done some stuff with factions, quests and dialogue etc. What I would like to know is how people generally work with the .esp files. Do you make NPCs in one and maps in others for example, and then export and import them into single mod file after some how? How do people work together on the same mod with different .esp files?
