Sunken ruin
A low-poly two-column arch sinking into bog mud: crown blocks fallen, flagstone slabs tipped and moss-eaten, with a carved slab, fallen column drums, a gnarled root, glowing crystals and mist wisps.

Left rail: colours and the 5 knobs the agent wrote into this model — they rebuild the geometry and go into your download. Right rail: looks for the viewer. Drag to orbit, scroll to zoom.

The brief given to 1DesignTool's “3D object” template:
Sunken ruin for the Enchanted Swamp 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 Enchanted Swamp kit (Low-poly style, flat-lowpoly direction): A foggy bog with a witch's hut. Use ONLY the kit palette, by name: moss green #3a883a, murky teal #2d5353, purple #6e3a88, bone #e4ddcd, moss green dark #235223, murky teal dark #122121, moss green light #5db15d, murky teal light #4d8080, 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 `fogDensity` (0–1, default 0.5) for the kit's "Fog density" setting wherever it makes sense on this part, and keep that id.

Note: Real-world scale ~4.5m x 3.9m footprint, 2.8m tall at the arch crown; every part rests on y=0. Materials are named after kit palette colours for set-wide recolouring. `fogDensity` drives the viewer's scene fog and the mist wisps' opacity — the exported GLB carries only the wisps' base transparency. `intact` removes arch blocks crown-first; above ~0.85 the keystone sits in the crown (visibly slipped), below that it lies fallen on the front slab. 3676 triangles, static (no clips), single-sided faces.
