You have to do it an photoshop and redirect all of the .paa. Not exactly sure how you would do this mission file, but it should be possible. You will have to copy files over from the dayz_code. If you dont know how to do this, you are starting much too advanced and you should learn how to add some scripts that do require you to change these things. Basebuilding, Self bloodbag, Salvaging, Knockout, and Siphon are all such scripts.
