Walkable demo
Station assembly yard
Walk around an orbital station laid out from the Orbital Station and Docking Bays pack: a six-port hub with a cupola, habitation and lab modules, an airlock, a docked crew ferry, a cargo freighter and tanker, and a truss with solar wings and radiators.
About
One station from 23 of the pack's 60 models, in the open preset with a black sky, a dim blue horizon and hard sunlight, and no ground at all.
You start beside the docked crew ferry and walk along the habitation module to the hub, where the cupola sits on top and the expandable habitat, the research lab with its four-port node and the compact lab with the airlock meet it. Two crew in EVA suits and an inspection drone work outside. Behind the modules the truss runs 34 m with end caps, two deployed solar array wings, two radiator arrays, the station manipulator arm, the dexterous manipulator, the high-gain dish and an external stowage platform. The cargo freighter, the propellant tanker and a service module hold station nearby.
Nothing moves: this pack ships without animation clips, so the arrays and the arms are static. Orbit, microgravity and the interiors are yours to add; the modules are closed shells.
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
Docked ferry
The crew ferry capsule and its service module docked to the end of the habitation module. There is no ground here: the fence is the only thing under your feet.
Crew ferry capsule and service module (Orbital Station and Docking Bays)Habitation module
The 9 m crew habitation module runs from the hub to the ferry, with two crew in EVA suits outside it and an inspection drone overhead.
Crew habitation module (Orbital Station and Docking Bays)The hub
A six-port pressurised hub with the cupola on top. Modules meet it on four sides: habitation, the expandable habitat, the research lab and the compact lab.
Six-port pressurised hub (Orbital Station and Docking Bays)Research lab
The 11 m research laboratory module turned along the station axis, with a four-port node beyond it and the propellant tanker and service module parked nearby.
Research laboratory module (Orbital Station and Docking Bays)Airlock
The compact lab and the crew airlock module on the other side, with the automated cargo freighter holding station beside them.
Crew airlock module (Orbital Station and Docking Bays)Truss and arrays
Eight truss bay segments with end caps, two solar array wings and two radiator arrays, the manipulator arms and the high-gain dish. Segments are 4.2 m so a truss is placed at 4.2 m steps.

Models in this demo
Truss bay segment (Orbital Station and Docking Bays)
A 4 m aluminium truss bay on a 2.4 m square section: four longerons, ribbed bulkhead frames, cross bracing, corner end fittings, a utility box, an EVA rail and a grapple fixture.
Truss end cap (Orbital Station and Docking Bays)
A 2 m closed truss end: half bay, a plated bulkhead with four fluid couplings, an avionics box, a low-gain antenna mast and one truss port so a run can be terminated.
Deployed solar array wing (Orbital Station and Docking Bays)
An 11.5 m deployed photovoltaic wing: a rotating base canister on a named gimbal node, a lattice mast and two 9.2 by 3.3 m blankets with cell strips, edge battens and a tensioning bar.
Deployed radiator panel array (Orbital Station and Docking Bays)
A deployed thermal radiator: a pump and rotary bracket on a truss port, a spine beam and three 3.4 by 2.6 m panels fanned on named hinge nodes with fluid line ribs.
High gain antenna dish (Orbital Station and Docking Bays)
A 2.3 m steerable high gain antenna: a bolted base, a two-axis gimbal on named azimuth and elevation nodes, a parabolic reflector with a stiffening rim and a feed horn on three struts.
External stowage platform (Orbital Station and Docking Bays)
A 3.2 by 2 m external stowage platform: a slatted deck on standoffs, four spare orbital replacement units under tie-down straps, a side bracket with a truss port, a grapple fixture and an EVA rail.
Station manipulator arm (Orbital Station and Docking Bays)
An 11 m six-joint station manipulator posed mid-reach: a latching base platform with a grapple fixture, two blanketed booms with cable conduits, six named joint nodes, an elbow camera with work lights and a snare end effector.
Dexterous two-arm manipulator (Orbital Station and Docking Bays)
A 3.4 m dexterous manipulator: a grapple body with a rolling torso node, a shoulder beam carrying two three-joint arms with parallel-jaw grippers, a stereo camera head and two tool holsters.
Six-port pressurised hub (Orbital Station and Docking Bays)
A 4.1 m six-port hub with forward, aft, port, starboard, zenith and nadir hatches on machined radial stubs, diagonal gusset structure between the stubs and four EVA rail runs.
