Airlock door

A low-poly Mars colony airlock: a white bulkhead frame on a hazard-striped sill with a rust red pressure hatch, porthole, locking handwheel and orange warning beacon. A baked 10 s loop unlocks the wheel, swings the hatch open on its hinge, closes it and locks it again while the beacon turns.

How it was made

The brief given to 1DesignTool's “3D object” template:

Airlock door for the Mars Colony kit. Design it as one clear asset at believable real-world scale for that setting (state the size in metres in meta.notes), with its main parts modelled and named, readable at thumbnail size and from every orbit angle. It moves: author a seamless baked loop (2–12 s) with every pivot exactly at its hinge, axle or swivel, and keep the base still. This is one part of the Mars Colony kit (Low-poly style, flat-lowpoly direction): A first settlement on red dust. Use ONLY the kit palette, by name: rust red #c32222, white #f4f1ec, solar blue #2e67b8, hazard orange #ed7e1d, rust red dark #821717, white dark #d7cebc, rust red light #db5757, white light #f9f8f6, soot black #1b1b22, warm white #f2ede2, mid grey #7d828c, dark wood #3d2a1c. Every material's `name` must be exactly the palette colour it uses — the GLB carries these names so the kit recolours as one; an unnamed material fails delivery. Kit knob: expose a param `dustStormLevel` (0–1, default 0.5) for the kit's "Dust storm level" setting wherever it makes sense on this part, and keep that id.

Note: Real-world scale in metres: about 2.9 m wide (sill) × 3.07 m tall (beacon top) × 1.3 m deep, with a 1.1 m × 2.0 m clear opening; origin at the bottom centre, front faces +Z. 1528 triangles, 10 materials named exactly by Mars Colony palette colour (the role is in each material's userData.role). The baked clip 'scene-motion' (10 s, seamless) turns the handwheel to unlock, swings the hatch about 95° out on its hinge pin, closes it, re-locks it, and turns the beacon head a whole number of times. Every pivot sits on its hinge, axle or swivel, and the sill and frame never move. Part ids use the hyphen-free slug 'marscolonyairlockdoor.*' because the kit's part-id validator rejects hyphens. dustStormLevel scales the dust drifts and the dust stain on the hatch, and sets the beacon spin rate (3–7 turns per loop); at 0 the dust is hidden. The GLB was exported at the default params (dust 0.5, 95° swing), so changing params only affects the live viewer until you re-export. glb-lint: 0 errors and 4 heuristic warnings: deliberate embedded joins, parts mounted on the frame mesh, a 3 m height versus the 1 m reference, and non-indexed merged stripe meshes.
