Twig bridges

A fairy-scale arched footbridge built from two tapered twig stringers, a jittered plank deck, sagging twig handrails lashed with twine, plus moss tufts and tiny mushrooms growing off the timber.

How it was made

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

Twig bridges for the Fairy Mushroom Glade 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 is a modular piece that snaps on a 1 m grid: give it a length in whole metres and put the origin at its snapping end, stated in meta.notes. This is one part of the Fairy Mushroom Glade kit (Low-poly style, flat-lowpoly direction): A tiny village built into giant mushrooms. Use ONLY the kit palette, by name: red cap #c32222, cream #f1e7d0, leaf green #3a883a, petal pink #e085a3, red cap dark #821717, cream dark #e0c994, red cap light #db5757, 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 `mushroomColour` (0–1, default 0.5) for the kit's "Mushroom colour" setting wherever it makes sense on this part, and keep that id.

Note: 2.0 m long × 0.62 m high × 0.56 m wide overall at default params (length scales 1–4 m in whole metres). Modular on a 1 m grid: the origin sits at the bottom centre of the snapping end (x = 0) and the bridge spans +X, so two copies butt cleanly end-to-end; both ends rest on y = 0 (bounds skim −0.002 m from a tilted mushroom base — visually imperceptible). Static: no animation clip in the GLB. Every material name is a Fairy Mushroom Glade palette colour; mushroomColour (0–1) quantizes the cap material across petal pink → red cap light → red cap → red cap dark, so its name always matches its colour. GLB carries 9 named meshes / 9 palette-named material slots; glb-lint flags exporter-cloned duplicate materials (same name+colour per mesh, which is what keeps the recolour-by-name contract) and intentional sibling contact (lashings wrap stringers, moss hugs timber) — neither is a defect. Subject-only export: ground disc and lights exist only in the viewer scene.
