Hello there ! So i was playing around and found a cool mod for the zombies called Renasiance ! So after some time i decided to make my own editing , And for reference i'm trying to edit Nacht der Untoten , I want to use some of the map parts which is not accessable to players,, And make it possible for players to move around and edit some things in the map , How can i do that ? Like edit the actul map? And if possible , How to apply this to Renassiance mod? So i have the edited map with the mod? Like combining them in one new mod? Or running two mods *if possible* and really thanks in advance !! 

P.S : I'm newbie and actully noob at editing so if some help is provided and links aswell, I would be really happy
