Thanks for replies :smile: @kitcat81: The Kiddie Kingdow Castle is a great place. Probably a lot of work involved, thanks for the suggestion. @BlahBlahDEEBlahBlah: If i understand right, you suggest me to create 1 plugin / settlement. For example i will have: NWS - Mulligan's Mine NWS - Fizze Grille (maybe include work by Joeyyx) NWS - Northpoint Reservoir So i can easily update features and track bugs on each settlement. But later i'm free to create a compilation like: Nuka World Settlements - All settlements It's a very light way to do it, but i'm wondering about performance issues ? Is it really a good practice because i'm going to duplicate scripts or custom objects definitions on each .esp. There is no way to merge multiple esp in one ? But it worth pointing out that it's a great way to collaborate with other modders and include already existing mods. I don't know how teams works on mods because it's not possible to use version control merging tools on ESPs. I'm not enough experienced with the creation kit and Fallout 4 modding to take a decision, so here i require your help. @genolune: omg the DRG center, that seems awesome ! For sure, i sent you an answer. So here is the zone i'm interested in. http://image.noelshack.com/fichiers/2017/52/1483307622-drg-e-min.jpg
