Rotating ring

A low-poly shipyard assembly ring, 20 m across, standing on edge in a deep-blue roller cradle. The white-faced ring with its orange roller track turns one full revolution per loop on three black drive rollers, with inward tool pods and a band of progress lights. Part of the Orbital Shipyard kit.

How it was made

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

Rotating ring for the Orbital Shipyard 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 Orbital Shipyard kit (Low-poly style, flat-lowpoly direction): Ships under construction in open space. Use ONLY the kit palette, by name: white #f4f1ec, orange #ed7e1d, deep space blue #1b447e, silver #b9bfc6, white dark #d7cebc, orange dark #af590e, white light #f9f8f6, orange light #eea668, 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 `shipCompletionStage` (0–1, default 0.5) for the kit's "Ship completion stage" setting wherever it makes sense on this part, and keep that id.

Note: Real-world size: ring 20.5 m outer diameter (flanges), 7.9 m deep including the deck, 23.25 m tall overall; ring centre axle at 12.6 m. Origin is the bottom centre of the deck at y = 0; front faces +Z, ring axle runs along Z. The baked 8 s clip 'scene-motion' is one full clockwise turn of the ring about its centre axle, while the three rollers counter-rotate exactly 12 turns about their own axles, so the loop is seamless. The deck, pillars, bearings and drive motor never move. The GLB's static pose is the t = 2 s frame (ring a quarter turn round). shipCompletionStage lights that fraction of the 24 progress tiles on each ring face; it, ringDiameter, ringDepth and toolPods are build-time params, and the GLB carries the defaults. Part ids use the hyphen-free root 'orbitalshipyardrotatingring' because the kit's part-id rule rejects hyphens. Materials are named by palette colour (8 distinct colours), but the exporter writes one material copy per mesh (27 entries) — recolour by name. Geometry is non-indexed with per-face normals so the faceted look survives in any engine. glb-lint: 0 errors; its warnings are heuristics (duplicate same-name materials, non-indexed flat geometry, deliberate embedded joins, 23 m height vs a 1 m reference).
