I've got a decently fleshed out idea in my head of an underground, pre-war bunker with all the bells and whistles. If you'll indulge me for a bit... Location: Little Rock Campground (unmarked, unnamed, undocumented location south of the Smith Mesa Prospector Camp) The location is noteworthy as when you reach the edge, (literally just a few feet from the wood plank seats), of the tiny camp, the ambient music changes. It's an exceptionally small area, complete with a rusted out Cryslus Corvega, some long, 4Ã4 planks, serving as bench seats, a useable unlit campfire, a banana yucca plant next to a large Boulder, and a Nevada agave plant. My idea is to create an interior space with quite a few different utilities inside, including, but not limited to, planters, an oven, a (useable) hot plate, a sinks, a toilet, (all rad free), a fridge, dining table and chairs, a double bed with blankets and sheets, a toggleable Nuka-Cola lamp (the version with light up bottle base), a night stand, dresser, first aid kit, safe (probably stocked with pre war money and a unique "pre war" gun of my own design), a kitchen, a living room, a bedroom, a bathroom, and a workshop, lockers in the workshop, workshop crates, reloading bench, work bench, varying rugs, a radio set to new vegas radio, a ham radio, a pc documenting the life of the wealthy couple would had this bunker built with entries of their visits over the years, though no skeletons will be present, leading the player to believe they never put it to use, (refer to a specific entry I've yet to create where the husband says something about these being tense times and war seems to be on the horizon. "I've had this bunker built as a last resort. I just hope I never have to use it." string lights (like the ones found in the Love Machine theme house in FO3), a few pre war posters of various things on the walls... The ideas are all there, I just need to make them a reality.

I'm brand new to modding, let's just get that out of the way. After watching a few tutorials on creating interior spaces in New Vegas, I feel it's a relatively easy task, however, my main question is, how would I go about placing a new entrance into the Mojave Wasteland world space?
