Collapsed entrance

A caved-in cavern entrance: two rock buttresses carry a snapped lintel slab dropped onto a rubble heap, with a dark slit of passage, broken mine timbers and a gold spill leaking out — the sealed mouth of the Dragon's Hoard Cavern.

How it was made

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

Collapsed entrance for the Dragon's Hoard Cavern 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 Dragon's Hoard Cavern kit (Low-poly style, flat-lowpoly direction): A vast cave piled with treasure. Use ONLY the kit palette, by name: gold #d0a225, ruby red #c32222, obsidian #17161d, cave blue #2e67b8, gold dark #8f7019, ruby red dark #821717, gold light #debd63, ruby red light #db5757, 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 `dragonColourAndSize` (0–1, default 0.5) for the kit's "Dragon colour and size" setting wherever it makes sense on this part, and keep that id.

Note: Static prop, ~4.1 m tall and ~5.7 × 4.1 m footprint at the default seed — the collapsed mouth of a dragon hoard cavern. dragonColourAndSize scales the whole formation 0.8×–1.35× and switches the five crystals across three palette stops (cave blue → gold → ruby red); the shipped GLB shows the t=0.5 gold. collapse raises the rubble crest and drops the lintel; the dark slit between them stays open across the range. glb-lint reports 29 material slots because the exporter clones the authored palette materials per mesh — every slot is named an exact kit palette colour; overlap/detached-part warnings flag intended embeddings (fracture facets, embedded crystals, the wedged headtree) verified in captures. Rubble/scree merge to non-indexed facets by design (flat shading). No textures, no animation clips.
