Build a Mechanic Girl Figurine with GPT-6 Astra and V2Fun

Overview

This case turns a little girl playing with a tin robot into a complete standing 3D figurine. Her yellow work helmet, blue overalls, brown boots, handheld remote, and hanging tool case establish the mechanic theme.

The technical notes describe GPT-6 Astra as the planner for structural understanding and task decomposition, with V2Fun handling complex model generation. The process image makes that division concrete: two generated character components sit alongside four groups of procedural accessories. This follows the broader GPT-6 Astra and V2Fun 3D agent workflow. No case-specific token savings or timing measurements are supplied.

Tools Used

• GPT-6 Astra: structural understanding and task planning, as described in the technical notes.
• V2Fun: generated reference images and the head-and-hair and clothed-body 3D components, as identified in the presentation.
• Three.js: procedural construction of the helmet, toy robot, remote control, and tool case with strap, according to the component labels.
• GLB: the supplied final asset format.

Step 1 — Prepare Isolated Character References

The input presentation shows the original complete character beside two modeling references: an isolated head with hair and neck, and a clothed body with the handheld props removed. Both isolated references are labeled as V2Fun-generated, AI-inferred views.

Removing the helmet exposes a reconstructed hairstyle, while removing the props makes the clothing and hand poses easier to see. These studies supply separate modeling targets; hidden hair and covered surfaces remain interpretations of the original image. The AI 3D model input guide provides related guidance on reducing occlusion and preparing clear references.

Step 2 — Divide the Figurine into Six Component Groups

The exploded process view documents six groups:

1. Clothed body, including the shirt, overalls, gloves, and boots.
2. Head and hair, including the face, neck, and ponytail.
3. Safety helmet with a brim and gear badge.
4. Tin toy robot with round eyes, joint details, and red feet.
5. Remote control with buttons, a joystick, and an antenna.
6. Tool case with buckles and a shoulder strap.

The separated positions are display offsets used to explain the assembly. Surface details remain with their parent components in this presentation.

Step 3 — Generate the Character and Build the Accessories

The process view identifies the clothed body and head-and-hair meshes as V2Fun-generated 3D. The face, hairstyle, clothing folds, and boots carry the character's organic and fabric detail. These parts illustrate the role of the V2Fun AI 3D model generator in the case.

The four accessory groups are labeled as Three.js procedural work. Their visible details include the helmet's raised ridges, the robot's box-shaped torso and gear emblem, the remote's antenna, and the case's handle and hanging strap. Together, these components demonstrate a hybrid construction approach within one character asset.

Step 4 — Assemble and Present the Final Model

The final image shows the head joined to the body, the yellow helmet placed over the hair, the robot held in one hand, and the remote held in the other. A brown strap crosses the torso and supports the tool case at the hip. Both boots meet the ground in a standing pose.

The final presentation identifies this view as a render of the delivered GLB after reloading, with no AI redraw. It describes the asset as static with embedded textures and notes that hidden surfaces are inferred. These are documented presentation details rather than an independent inspection of the file.

Workflow

Original character reference → isolated head and body references → six component groups → V2Fun character generation and Three.js accessory construction → complete assembly → GLB delivery and documented reload render.

Prompt

A fully assembled figurine of a little girl playing with a robot, wearing a small worker's hat. She holds a tin robot in one hand and a remote control in the other, with a repair tool case secured at her waist. All accessories are fully assembled on the standing figure. Use a pure white background, professional studio lighting, and a highly detailed 3D anime figurine display style.

Result

The final presentation preserves the requested standing character and all major accessories. It uses a warm cream backdrop with a cast shadow, while the prompt requested pure white. The yellow helmet, dark overalls, metal-colored robot, and tool case remain clearly distinguishable in the assembled view.
