How it was made

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

Holo adverts for the Cyberpunk Alley 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 Cyberpunk Alley kit (Low-poly style, flat-lowpoly direction): A rain-soaked back street under neon. Use ONLY the kit palette, by name: black #151619, neon pink #f994b6, cyan #20c6df, sodium yellow #eecd2b, black dark #090a0b, neon pink dark #f64c84, black light #3a3c40, neon pink light #fcdee8, 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 `neonColours` (0–1, default 0.5) for the kit's "Neon colours" setting wherever it makes sense on this part, and keep that id.

Note: Static street prop, 2.9 m tall and about 1.3 m wide x 0.65 m deep at default params. Origin at bottom centre, the plinth rests on y = 0, and the main panel faces +Z. Every GLB material is named exactly by its kit palette colour (black, neon pink, cyan, sodium yellow ...) so the kit recolours as one; neon colours also carry a matching emissive. neonColours (Neon colours, 0-1) sets how strongly the neon materials glow: 0 = sign off, 0.5 = gentle glow, 1 = full glow. It changes emissive strength only, never the base colours. mastHeight lengthens the mast and the main panel together; panelCount 1-3 keeps the main panel, then adds the cyan banner, then the yellow blade sign; bannerTurn swings the top banner around the mast. Part ids use the root 'holoadverts' because the kit's plan checker does not allow hyphens in part ids. Advert graphics are modelled blocks that pass through each sheet, so the back shows the mirrored projection; there is no text, logo or texture. The ground disc, light rig and the exposure tweak (0.85, used to keep the neon from washing out) belong to the viewer only and are not in the GLB, which carries no animation clip. The exporter clones each mesh's material, so the file lists 47 materials, all named from the palette above. glb-lint's material-count, duplicate-material, sibling-overlap and detached-part warnings come from that cloning and from deliberate embedded joins (sheets inside their emitter bars, arms inside the mast, cap over the mast top). glb-lint reports 0 errors and 5 warnings; its overall verdict reads UNVERIFIED only because no requirements contract was supplied. Exported model: 656 triangles.
