Barnacle & Brass

A stylized deep-sea salvage world: the Brass Diver works the kelp gullies and the wreck of the Gilded Gannet from a wooden tender barge on the surface. One committed palette — deep teal, aged brass with verdigris, cream waxed canvas, coral-red accents — across every sheet. The pack shipped only after its hero was actually modelled from the turnaround: the buildability probe below is the proof.

Key art

Barnacle & Brass key art — the Brass Diver hauls a salvage crate through a kelp gully

Orthographic turnaround

The modelling contract: four views, identical equipment, consistent proportions. Aged brass with verdigris patina, open-glass bolted portholes, perforated top vent, leather belt, dark gloves, weighted boots.

Environment zones

Zone: Kelp Gully — sunlit sandy path between kelp-covered rock walls

Kelp Gully — the bright shallows: rippled sand, emerald kelp ribbons, coral-red starfish.

Zone: Wreck of the Gilded Gannet — a broken hull in dark teal water

Wreck of the Gilded Gannet — the dark zone: matte verdigris portholes, spilled crates, coral rope.

Zone: Surface Tender Barge — brass air pump, crane winch and crates on a wooden barge

Surface Tender Barge — above the water: the air pump, hose coils and crane the diver works from.

Props & materials

Prop sheet — winch, hose reel, salvage crate, pry bar, porthole, buoy, weighted boots

Seven props at one scale: hand winch, hose reel, salvage crate, pry bar, porthole, message buoy, weighted boots.

Material board — eight swatch spheres from aged brass to mother-of-pearl

Eight materials: aged brass, verdigris copper, waxed canvas, coral rope, barnacled iron, wet sand, kelp, mother-of-pearl.

The buildability probe

A pack only ships after an asset has actually been modelled from it. The Brass Diver below was authored headless in Blender from the turnaround sheet alone — fused canvas volumes, curve-tube limbs, brass fittings — across seven audit-driven rounds, then compared back against the sheet for silhouette, proportions and signature details. Verdict: the turnaround under-specified nothing.

What the pack proved. Enumerated per-position prompts fix swatch-count drift on material boards; a framed-poster border clause keeps four-view turnarounds fully inside the frame; and any element left unnamed in a prompt (glove colour, vent pattern) will drift between sheets — the element inventory is the contract that catches it. Full findings feed the platform's concept generation pipeline.
