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.

How it was made

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

Observatory dome for the Wizard's Tower 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 Wizard's Tower kit (Low-poly style, flat-lowpoly direction): A crooked tower on a cliff, full of experiments. Use ONLY the kit palette, by name: midnight blue #1d2448, deep violet #4b2a6b, lavender #8a6fb3, brass #b08d3c, aged gold #8a6a22, candle yellow #f2c94c, flame orange #e8833a, stone grey #6e6f78, dark stone #3e3f47, cliff slate #55606e, parchment #e7d7b1, oak brown #6b4a2f, dark wood #3d2a1c, moss green #5f7d4a, rune cyan #5fd3e6, soot black #1b1b22. 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 `towerHeight` (0–1, default 0.5) for the kit's "Tower height" setting wherever it makes sense on this part, and keep that id.

Note: Real-world scale: ~4.0 m tall, ~4.6 m stone footprint (the telescope outrigger reaches ~4.9 m front-to-back). Metres, +Y up, front +Z, origin at bottom centre. towerHeight drives the drum collar height; domeHeight rescales the dome profile; telescopeTilt and shutterOpen pose the scope and doors; magicGlow only changes emissive intensity of candle-yellow and rune-cyan materials. Static piece: no baked clip. Staging (ground disc, light rig) lives outside the model root and is not exported.
