Walkable demo
Moon base
Walk an established lunar base from the Lunar Surface Colony and Rovers pack: thirteen habitats and tunnels mated on the hab-port grid, a solar field and reactor, a landing pad with blast walls, the whole rover fleet, a regolith works and crews on EVA.
About
One base from 45 of the pack's 54 models on plain regolith in the space preset: a star field down to the horizon, the Earth low in the sky, and hard white sunlight.
You start outside the front airlock with three crew on EVA. Behind it the regolith-shielded habitat meets a tunnel spine of three tee junctions and two straight bays; every mate is a hab-port on the 6 m site grid, and no tunnel port is left open. The west end carries the medical module and the workshop and vehicle bay; the greenhouse runs north through a quarter-turn tunnel into the inflatable dome and its cupola; a third straight bay leads north to the logistics module, the crew habitat and a second cupola; and the regolith-shielded dome ends the spine at a second airlock facing the landing pad.
North-west is the power field: five solar rows, the vertical solar tower, radiator banks, battery containers and the reactor behind its berm, with the relay mast beside it. North-east the crew lander stands on the sintered pad behind two blast deflector walls and five approach beacons, with the cryogenic tank farm, the transfer arm and two tanker haulers. South-east is the rover park with every rover in the pack, most of them more than once, and the cargo lander with its ramp down behind two blast berms. South-west is the regolith works: excavator, hopper and screening deck, oxygen and water skids, the sintering print gantry, three stockpiles and survey markers. Crews, tool carts and sleds are placed wherever the work is.
Nothing moves: this pack ships without animation clips. The five terrain tiles are not placed, since each carries 1.3 to 3.4 m of relief that would stand as a slab on the demo's flat floor. The domes are round, so their square bounding boxes touch the neighbouring module corners without the geometry meeting.
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
Front airlock
The dust-lock airlock is the front door: a crew of three suits up outside it with a tool cart and a sled. Behind it the regolith-shielded habitat joins the tunnel spine.
Airlock with dust-lock vestibule (Moon Base Colony and Lunar Rovers)Tunnel spine
Three tee junctions and three straight bays make the spine. Every module mates through the hab-port 2.4 m above the regolith, so module centres fall on the 6 m site grid.
Pressurised connecting tunnel, tee junction (Moon Base Colony and Lunar Rovers)Medical and workshop
The west end of the spine holds the medical and crew care module, with the pressurised workshop and vehicle bay hung off its side port. A flatbed hauler, batteries and radiators line the plot edge.
Pressurised workshop and vehicle bay (Moon Base Colony and Lunar Rovers)Greenhouse and dome
The greenhouse runs north from the west junction to a quarter-turn tunnel, then east into the inflatable dome and its observation cupola. The solar field and the shielded reactor stand beyond.
Inflatable dome habitat (Moon Base Colony and Lunar Rovers)Shielded dome
The regolith-shielded dome ends the spine at the east airlock, which opens onto the tank farm and the landing pad. The north arm behind it runs a straight bay, the logistics module, the crew habitat and a second cupola.
Inflatable dome habitat with regolith shielding (Moon Base Colony and Lunar Rovers)Landing pad
The crew lander sits on the sintered pad behind two blast deflector walls, with five approach beacons around it. The cryogenic tank farm and transfer arm fill the two tanker haulers beside the east airlock.
Crew lander with ascent cabin (Moon Base Colony and Lunar Rovers)Rover park
The whole fleet: two pressurised rovers, four open rovers, two crane rovers, three flatbed haulers, two tankers and seven survey rovers. The cargo lander has its ramp down behind two blast berms.
Pressurised long range rover (Moon Base Colony and Lunar Rovers)Regolith works
The excavator feeds the hopper and screening deck; the oxygen and water skids and the sintering print gantry work beside it, with three graded regolith stockpiles behind.
