Drifting jellies

Three low-poly deep-sea jellyfish with glowing cyan rims and magenta oral arms drift and pulse above a faceted seabed rock dotted with glow polyps. Includes a seamless 6-second swim loop.

How it was made

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

Drifting jellies 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. It moves: author a seamless baked loop (2–12 s) with every pivot exactly at its hinge, axle or swivel, and keep the base still. 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: the whole piece is about 0.88 m wide, 1.15 m tall and 0.80 m deep (1.17 m at the top of the swim). Bells are 0.36 m, 0.27 m and 0.20 m across. The seabed rock rests on y = 0 and never moves; the jellies drift freely above it by design, attached to nothing. The GLB has 2,440 triangles, 7 materials named after their Deep Sea Abyss palette colours (glow cyan dark, glow cyan light, glow cyan, magenta, vent orange, abyss black light, abyss black), and one baked 6 s looping clip, "scene-motion" (bell pulse, drift and bob, rim-hinged tentacle and oral-arm sway). Glow parts use a dim baked emissive colour; there are no textures, and facet normals are baked in so the model stays flat-shaded in any engine. The four params rebuild the model in the 1DesignTool viewer; the GLB is exported at the defaults. Glow colour switches the rims, tentacles and polyps between magenta (0 to 0.33), glow cyan (0.33 to 0.67) and vent orange (0.67 to 1). Tentacle length also raises the jellies so the tips stay clear of the rock. glb-lint reported no errors but three heuristic warnings, all intentional: non-indexed primitives (from the baked flat normals), nested sibling boxes (bell layers, polyps seated in the rock) and hinge-attached tentacle meshes reading as detached. Its overall verdict is UNVERIFIED only because no requirements contract was supplied.
