Arches

A three-bay lilac arcade with faceted round arches you can see through. It stands on a checkerboard plinth, and a stepped stair on the roof climbs to a gold doorway that opens onto the sky.

How it was made

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

Arches for the Dream Maze 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 Dream Maze kit (Low-poly style, flat-lowpoly direction): Stairs that go nowhere and doors in the sky. Use ONLY the kit palette, by name: lilac #b89fd1, cream #f1e7d0, checker black and white #f4f1ec, gold #d0a225, lilac dark #916bb8, cream dark #e0c994, lilac light #ded4e8, cream light #fbf9f4, 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 `gravityDirection` (0–1, default 0.5) for the kit's "Gravity direction" setting wherever it makes sense on this part, and keep that id.

Note: Real scale: 9.2 m long × 2.4 m deep × 7.51 m tall (arch openings 2.0 m wide with crowns 3.2 m above the plinth, a 0.9 m thick wall, a 1.2 m rooftop stair and a 1.8 m sky door). The origin is at the bottom centre, the model rests on y = 0, and the front faces +Z. It is 1,712 triangles with 9 materials, and each material is named after its Dream Maze palette colour. There are no textures and no animation. The checkerboard is modelled tiles, and normals are baked flat so the facets survive in any engine. gravityDirection moves where the rooftop stair peaks: 0 climbs to the west (−X) end, 1 to the east (+X) end, and 0.5 rises from both ends to a central landing. The sky door always stands on that landing. bays, bayWidth and archHeight rebuild the arcade. All params change the viewer only; the GLB is a snapshot at the default values. Mesh nodes carry dream-maze-arches.* ids. Their parent assembly groups use plain ids (arches, arches.base, arches.arcade, arches.trim, arches.crown) because the kit's plan grammar has no hyphens. glb-lint has 0 errors. Its verdict prints UNVERIFIED only because no requirements contract exists. It also gives two accepted warnings: the 7.5 m height is the true scale, and the overlaps are intended (checker tiles interleave, dressed stones sit embedded in the piers). The viewer uses exposure 0.85 rather than the direction's 1.05 so the pastel palette keeps its hue. OBJ export carries geometry only.
