How it was made

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

Giant trunk sections 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. 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.

Note: Static asset: no clip is baked or exported (index.html's bakeClip line removed). The season knob cross-fades the foliage between leaf green and soft gold using two palette-pure materials; foliageAmount scales both. Part ids use the hyphen-free root 'gianttrunk' because the library's part-id regex disallows hyphens; all 15 planned ids were verified present in the reloaded GLB. Geometry is intentionally non-indexed with baked per-face normals so the flat-lowpoly facet look survives glTF export (glTF has no flatShading flag) — glb-lint's unindexed warning is that intended trade. The 390px portrait capture crops the trunk ends slightly; the asset is composed for landscape framing. Real-world scale: a 2.4 m long, 1.44 m diameter giant-trunk section, ~1.86 m tall with foliage.
