Harbor Tug

A drivable little tug with real boat feel: the nose leads the helm, velocity follows with drift lag, the hull banks into turns, and the three-blade prop spins with the throttle sign — it visibly reverses churn when you back astern, behind a rudder that deflects with the wheel. Light the five lantern buoys around the harbor at dusk; the rock shoal thumps you off course with a wash of spray but never traps you. The dusk itself is an inward-wound gradient skyband from apricot to indigo with early stars, over glassy teal water, a plank dock with a crook lamp, and harbor-wall silhouettes. Sampled nylon-guitar and harmonica over a real ocean loop; each buoy answers with a tubular bell.

The concept is the contract

The piece was concepted first — an AI key-art painting — and its hero assets were then code-modeled in headless Blender and audited against that concept. The pair below is the contract and the build.

A cozy little harbor at dusk: a small stout tugboat with a bright red hull, white wheelhouse with warm glowing windows, a cream funnel with a navy band, black tire bumpers along its gunwale and a small mast lamp, chugging across calm teal water with a gentle white wake; around it five floating lantern buoys with round striped floats and little glass lanterns, a weathered wooden dock on posts with a glowing lamp post and coiled rope, dark rock shoal breaking the surface to one side, apricot-and-rose dusk sky with a few early stars, distant harbor wall silhouette, calm nostalgic mood with soft shadows, high-end stylized 3D game render, no text, no watermark, no UI

Code-modeled in Blender

The hero assets were modelled by agents writing Blender code against the platform sculpt kit — no downloaded models anywhere — and rendered by the studio harness for audit before entering the engine scene.

Made by AI, compiled by the real Unity 6 engine

Four code-modeled Blender exports — tug (prop and rudder groups on their own stern pivot locators so the engine drives them with the throttle sign and helm), lantern buoy (instanced five times, re-lit on contact), plank dock and rock shoal — ship as named nodes. All sound is sampled — nylon guitar, harmonica, tubular bells, tuba horn, taiko and a real ocean-wash loop — never synthesized.
