(First time comment!) This is a very interesting subject - one that has actually been successfully attempted in different ways - both back in at least one FO3 Mod and in FONV, if anyone wants to check it out. For FO3 - an excellent and huge job done by chucksteel on the "DCInteriors Project" Mod for that game. It improved many of the city blocks and added hours of game play by enabling more exploration and combat - basically adding lots of cool interiors to many of the boarded up places throughout the DC wastes. In that mod, a number of the mainfloor storefront locations with windows allowed one to look out once inside and see the actual streets in the game - truly amazed when I saw that. Of course, since they were seperate interior cells, this meant they didn't show any characters outside - supermutants or centaurs walking around, or companions left waiting - but it did the job and looked awesome. This as a minimum shouldn't be hard to put in NV as it's much the same game, right? For FONV - check out "New Vegas Interiors West Vegas" Mod by RideTheCatfish, who is working with chucksteel - hope they do more because it looks great so far! No windows that I've found yet, though they may be there! Recently, in the mod "Red Rock Ranch" by northfield (excellent so far - I have yet to complete!), if you use the truck to fast-travel to the hunting cabin up in the mountains past Jacobstown (which is the only way to get there), when you enter - the door stays open, and when you go inside, turn around and look out the two windows, seeing your companions still standing outside as well as the dogs walking around - so cool. It must be that the whole place is in it's own worldspace - it's own exterior cell? Anyway - good idea! While not a modder myself - sure appreciate the work being done out there in the community. Keep up the great work, y'all! Oh - and death to Caesar!
