Rotating rooms

Two open-sided rooms on a black-and-white checker plinth: the lower room swivels on a central column, and the upper room tumbles end over end on a gold axle, so its open door hangs in the sky. Low-poly, flat-shaded, in the Dream Maze kit palette, with a seamless 12-second loop.

How it was made

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

Rotating rooms 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. 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 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-world scale in metres: the plinth is 4.76 m square, the lower room is 3.0 m with 2.7 m ceilings, and the upper room is a 2.4 m cube. The model stands about 7.0 m tall at rest; the top corner reaches 7.36 m mid-tumble. Two pivots move: the lower room turns about the column axis (Y, at x = 0, z = 0), and the upper room turns about its axle centre line (X, at y = 5.81 m). The plinth, column and yoke never move. The 12 s clip 'scene-motion' runs in four 3 s beats. In each beat the lower room makes an eased quarter turn and then the upper room does the same, so the loop closes exactly at 360°. The clip has tracks for those two pivot nodes only. gravityDirection sets the upper room's resting tilt: 0 is floor down, 0.5 is on its side (the default, with the door in the sky) and 1 is upside down. The tilt is baked into the exported pose and clip, so change it before exporting. Nodes with hyphen-free names (dreammazerotatingrooms.*) are empty identity wrappers left by the authoring checker; they can be ignored or collapsed. The GLB holds 10 distinct palette-named materials, but the exporter writes a copy for each mesh (23 in total). Every copy keeps its palette name, so recolouring by name still works. glb-lint reports no errors; its warnings cover that material duplication, the 7 m height against its 1 m reference, and parts that look detached only because of the wrapper nodes. roomSize and stairSteps were checked at their extremes by working through the dimensions, but those settings were not rendered.
