Anchors

A low-poly admiralty ship's anchor standing on its crown in a silt mound on the deep seabed. It has a banded wooden stock, a head ring and a chain that hangs down and trails across the floor, with barnacles and glowing polyps growing on it. Part of the Deep Sea Abyss kit.

How it was made

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

Anchors for the Deep Sea Abyss 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 Deep Sea Abyss kit (Low-poly style, flat-lowpoly direction): Black water and living lights. Use ONLY the kit palette, by name: abyss black #151619, glow cyan #20c6df, magenta #d02597, vent orange #ed7e1d, abyss black dark #090a0b, glow cyan dark #168a9c, abyss black light #3a3c40, glow cyan light #67d4e4, 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 `glowColour` (0–1, default 0.5) for the kit's "Glow colour" setting wherever it makes sense on this part, and keep that id.

Note: Real-world scale in metres: the anchor is 2.77 m tall to the top of its ring, with a 2.4 m shank, arms spanning about 1.8 m and a 2.16 m stock. With the default 1.4 m of chain on the seabed the whole piece covers 4.2 m × 2.67 m. Origin is at the bottom centre of that footprint, the model rests on y = 0, and the front faces +Z (the arms spread across X and the stock runs front to back). Static model with no animation clip. Every material is named after its Deep Sea Abyss palette colour. The exporter writes one material copy per mesh, so several materials share a name (10 materials, 6 colours); recolouring by name catches them all. The polyps carry an emissive colour equal to their base colour. glowColour sets the polyp colour. It snaps to palette swatches instead of blending, so the material name always matches a palette colour: 0–0.2 magenta, 0.2–0.4 glow cyan dark, 0.4–0.6 glow cyan (default), 0.6–0.8 glow cyan light, 0.8–1 vent orange. shankLength scales the whole forging, the silt mound and the polyps together. lean tilts the anchor toward its chain. chainRun 0 ends the chain where it touches down. The chain always hangs from the ring as a catenary that leads off to the right. In the viewer only, the shadow catcher, sun rig and exposure 0.85 are staging and are not part of the GLB. 3,254 triangles and 11 draw calls at default settings; the maximum is 4,728 triangles (short shank, full lean, 3 m of chain). glb-lint ran with 0 blocking errors and 4 advisory warnings (duplicate per-mesh materials, non-indexed flat-shaded primitives, intentional part nesting, scale versus a 1 m reference). Its verdict reads UNVERIFIED only because no requirements contract was supplied. The kit's plan-check rejects hyphens in part ids, but the library's slug-prefixed ids (deep-sea-abyss-anchors.*) were kept on purpose so they match the rest of the set.
