Build a Mechanic Hover Disc with GPT-6 Astra and V2Fun

Overview

This case pairs a cross-legged mechanic with a circular hover platform. The design brief combines organic detail—tousled hair, an expressive face, worn clothing, and folded limbs—with regular machinery built around concentric discs and cylindrical thrusters.

The supplied technical account assigns component planning and assembly calibration to GPT-6 Astra, with V2Fun generating complex forms and surface detail. The component sheet makes that division concrete: the textured character is identified as V2Fun-generated 3D, while the platform groups are labeled Three.js procedural. The broader GPT-6 Astra and V2Fun collaboration workflow explains this approach to combining generated geometry with agent-led construction.

Tools Used

• GPT-6 Astra: subject hierarchy analysis, component planning, and assembly calibration, as described in the technical account.
• V2Fun: generated visual references and the textured mechanic component, as identified in the reference and process sheets.
• Three.js: procedural structural links, body and seat, mechanical equipment, and controls/supports.
• GLB: the supplied final asset format.

Step 1 — Establish the Reference and Pose

The input sheet contains a complete concept reference, an isolated seated-character reference, and an inferred front, side, and rear study. All are labeled as V2Fun-generated references. The three-view study is explicitly AI-inferred, so its hidden-side details represent design interpretation rather than independently observed geometry.

The isolated character preserves the key pose: crossed legs, one hand extended toward a control grip, and the other resting near the knee. This separation provides a character-focused reference without the surrounding platform. The AI image generator for 3D references is relevant to this concept and reference preparation stage.

Step 2 — Separate the Character and Mechanical Groups

The exploded sheet presents five named groups: character, structural frame, body and seat, mechanical equipment, and controls and supports. Four short cylindrical thrusters appear together in the mechanical equipment group. The body group contains the layered circular platform and raised brown seating surface, while the control group shows a box-mounted upright lever.

The exploded arrangement uses display offsets to reveal the components. It illustrates their separation without establishing manufacturing joints or physical assembly tolerances.

Step 3 — Generate Organic Detail and Build Regular Geometry

V2Fun supplies the textured character, including the face, hair, vest, gloves, boots, and folded trousers. This is the case's documented use of image-to-3D model generation.

Three.js supplies the regular mechanical forms. The visible platform uses circular layers, a thick metallic outer body, repeated rectangular access plates, cylindrical propulsion housings, and a straight control shaft. Bronze-toned surfaces and blue-gray metal distinguish the main body from its rim, plates, and thrusters.

Step 4 — Assemble and Present the Delivered Model

The technical account describes returning the generated components to the agent for assembly calibration. In the final image, the mechanic sits on the raised seat with his extended hand positioned at the lever grip. The circular hull supports the composition, and three thruster housings are visible from the chosen view; the process sheet shows the four-piece set.

The final presentation identifies the image as a render of the delivered GLB after reloading, with no AI redraw. Compared with the concept reference, the final platform has cleaner metallic surfaces and a more pronounced curved brown seat border. It retains the central seated figure, circular silhouette, repeated access panels, and restrained ground shadow.

Workflow

Design brief → Generated concept and character references → Component planning → V2Fun character generation + Three.js mechanical construction → Assembly calibration → GLB export → Reloaded assembly render.

Prompt

English translation of the design intent:

An adult mechanic with tousled hair, wearing an old leather vest and loose work trousers, sits cross-legged at the center of a circular hovering platform. One hand grips a short joystick; the other rests on his knee. The platform consists of upper and lower concentric discs, a thick outer ring, and four evenly spaced short cylindrical thrusters. A slightly raised cushion sits on top, rectangular access covers repeat around the sides, and the underside has clear support relationships.

Use bronze and blue-gray metals. The platform hovers close to the ground with a soft shadow and no strong lighting effects. Create one complete standalone character-and-machine asset in a collectible-model style that combines realistic proportions with mild exaggeration, an expressive face, and natural clothing folds. Build the machinery from clear cylinders, discs, rectangular plates, straight rods, and a few regular curved tubes. Keep component boundaries and connections readable, preserving contact points with the seat, grip, and foot supports.

Show the entire centered subject with margins from a slightly elevated front three-quarter view. Use a white background, soft studio lighting, contact shadows, sharp component detail, and refined PBR materials. No text, numbers, logos, watermarks, complex scenery, or motion blur. Produce one finished reference image, not a collage or exploded view.
