Walkable demo
Lunar base
Walk a 63 by 56 metre lunar colony laid out from the Lunar Surface Colony and Rovers pack: shielded and inflatable habitats joined by tunnels, an airlock, greenhouse and workshop, five rovers, a landing pad with two landers, and the power yard.
About
One base from 24 of the pack's 54 models, on plain regolith in the outdoor preset with a black sky and hard sunlight.
You start outside the airlock with two crew in EVA suits. The regolith-shielded habitat is behind it, joined by a straight tunnel bay to the crew habitat on legs; the inflatable dome, the greenhouse, the medical module and the workshop and vehicle bay complete the base. Five rovers are parked to the south. To the west the crew lander stands on the sintered landing pad behind a blast deflector wall, with the cargo lander and its ramp and two approach beacons nearby. To the north are the nuclear power unit behind its berm, the propellant tank farm, three solar array rows, the solar tower and the relay mast.
Nothing moves: this pack ships without animation clips. The terrain tiles in the pack are not placed here, since they carry 2 m of relief; the ground is the demo's plain floor.
Every piece here is a published model from the pack, placed by hand. Walk with the keys or touch, and approach a piece to see it move if it has animation. Colliders, navigation and gameplay are yours to add.
Points of interest
Airlock
The airlock with its dust-lock vestibule is the front door of the base, with two crew in surface EVA suits outside it. Behind it is the regolith-shielded habitat.
Airlock with dust-lock vestibule (Lunar Surface Colony and Rovers)Crew habitat
A rigid cylinder crew habitat on legs, joined to the shielded habitat by a straight connecting tunnel bay. The tunnel is 6 m, so modules are placed 12 m apart to meet it.

The pressurised greenhouse module and the inflatable dome habitat on the west side, with the medical module and the workshop and vehicle bay on the east.
Pressurised greenhouse module (Lunar Surface Colony and Rovers)Rover park
Five rovers: pressurised long-range, open crew, the crane rover, a six-wheel cargo hauler with a flatbed and the small survey rover.
Pressurised long range rover (Lunar Surface Colony and Rovers)Landing area
