Habitat domes
A first Mars settlement: one faceted main habitat dome linked by ground-level tunnels to three annex domes (including a glass-capped greenhouse), with a round airlock porch, solar racks, life-support tanks and a comms mast.

Left rail: colours and the 5 knobs the agent wrote into this model — they rebuild the geometry and go into your download. Right rail: looks for the viewer. Drag to orbit, scroll to zoom.

The brief given to 1DesignTool's “3D object” template:
Habitat domes 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. 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: Static model (no clips). Rests exactly on y=0, front faces +Z, metres throughout. 7.2 m to the antenna tip; settlement footprint ~23.2 x 18.5 m; main dome ~10.7 m across its skirt ring. dustStormLevel scales the regolith drift mounds (0 nearly clears them). Tunnel and flange junctions are deliberately embedded in the dome shells. Every material is named by its Mars Colony palette colour; the exporter writes one material record per mesh, so deduplicate by name on import if needed.
