📋 About This Mod
Overview:
Let’s be honest.
You conquered an alien world, built a thriving outpost… and now you’re living inside a maze of pressurized metal tubes and spending most of your day cycling airlocks.
Graf’s BioDome fixes that.
This fully custom-built geodesic biodome allows you to create a temperate breathable interior environment at your outpost, no matter how hostile the planet outside may be. Build it on a frozen vacuum, a methane swamp, or your favorite radiation-blasted rock -- once inside the dome, you can remove your helmet and enjoy actual air like a proper human being.
Features:
-
[]Creates a breathable Earth-type atmosphere inside the dome
[
]Remove spacesuits and helmets regardless of planetary conditions[]Build standard outpost habs inside without needing airlocks on each hab
[]Large industrial airlock entrance allows vehicle entry
[]Appears in the Structures category
[]Fully vanilla compatible, no dependencies
Interior Space:
The BioDome contains enough interior volume to hold 20+ standard outpost hab modules side-by-side, allowing you to construct a complete enclosed colony within a single atmospheric shell.
Included with the BioDome are 8 built-in, interchangeable interior floor presets give you a finished floor to live on once you've built your habs and other structures inside the dome. Swap between them using the same yellow-highlight toggle system used for hab wall variants:
-
[]6 full-coverage flat floor presets -- complete level living space across the interior, with options including decorative trees and plants.
[
]1 full-coverage raised floor -- ramps up from the entrance to offer a better view outside[]1 minimal entry platform -- allows unrestricted structure placement
-
[]Place the BioDome.
[]Build habs and interior structures inside it.
[]Select your preferred interior floor preset. (In build edit mode, hover on the semi-cylindrical platform just inside the door and toggle through the available interior floor presets to select the one you prefer. Because of how Starfield handles structure foundations, habs cannot be placed directly on the dome’s built-in floor. The small starting platform lets you build without floor collisions.)
Design & Construction:
Built entirely from scratch in Blender and optimized for gameplay:
[]Custom geodesic dome mesh
[]Full custom collision
[]Fully navmeshed
[]Generated LOD meshes (visible on maps and at distance)
[*]Near-LOD meshes
-
[]6 full-coverage flat floor presets -- complete level living space across the interior, with options including decorative trees and plants.
