Rope and vine bridges

A low-poly rope and vine bridge module: sagging plank deck, twin rope handrails, bark anchor posts and leaf-wrapped vines. Snaps between treetop platforms on a 1 m grid.

How it was made

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

Rope and vine bridges for the Elven Treetop City 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 Elven Treetop City kit (Low-poly style, flat-lowpoly direction): Platforms and bridges high in giant trees. Use ONLY the kit palette, by name: leaf green #3a883a, silver #b9bfc6, bark brown #6b4a2e, soft gold #cfaf59, leaf green dark #235223, silver dark #8f99a3, leaf green light #5db15d, silver light #e4e6e7, 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 `season` (0–1, default 0.5) for the kit's "Season" setting wherever it makes sense on this part, and keep that id. Material names are the palette colour NAMES listed above (e.g. "leaf green", "dark wood") — never a hex code like "#3d2a1c".

Note: Units: metres, +Y up. Origin is at one snapping end of the deck (z = 0), the bridge runs +Z with a whole-metre length (4–12 m) and rests on y = 0 via the anchor posts; snap it to platforms on a 1 m grid. The `season` knob cross-fades light vs dark leaves (leaf green light ↔ leaf green dark) and their size; the GLB carries no animation clip. Rope rails, plank deck, anchor posts and vine leaves are merged/merged-primitive geometry (no instancing extension), so it loads offline in three.js, Godot, Unity and Blender.
