Text to 3D - AI 3D Model Generator

What is text to 3D generation?

Text to 3D generation converts a written description into a three-dimensional model. You describe shape, style, and materials, and the AI builds a GLB file you can preview, download, and use in games, 3D printing, AR/VR, and product visualization. Story321 offers two text to 3D models - Hunyuan 3D V3 and Meshy 6 - with transparent credit costs shown before you generate.

Text to 3D Generation Features

• Two AI Models in One Workflow

  Generate from text with Tencent's Hunyuan 3D V3 for detailed textured models, or Meshy 6 for production-ready GLB output with preview and full modes. Compare both on the same prompt.

• GLB Output for Any Pipeline

  Every text to 3D job exports a GLB (binary glTF) file, compatible with Blender, Unity, Unreal Engine, Three.js, and standard web viewers.

• In-Browser 3D Preview

  Rotate, zoom, and auto-rotate completed models in the built-in 3D viewer before you download, so you can verify geometry and textures first.

• Durable Generation History

  Signed-in text to 3D jobs are saved to your 3D history with status, model name, date, and credit cost, so you can return and download later.

Why Use Our Text to 3D Generator?

• No 3D Modeling Skills Required

  Traditional 3D modeling has a steep learning curve. With text to 3D, you describe what you want and the AI builds the model - no CAD or sculpting experience needed.

• Rapid Concept Iteration

  Generate a starting model in 30-90 seconds, review it in the viewer, adjust your prompt, and regenerate. Explore multiple directions without blocking an artist's time.

• Transparent Credit Costs

  The form shows the credit cost of your selected model and options before submission, and each saved record lists the credits used.

• Versatile Applications

  Use generated GLB assets for game prototyping, 3D printing, AR/VR scenes, product visualization, and marketing material.

How to Generate 3D Models from Text

1. 1

   Describe your model

   Write a detailed prompt covering shape, proportions, style, materials, and colors. Hunyuan 3D V3 accepts up to 1024 characters; Meshy 6 accepts up to 600.

2. 2

   Choose a model and settings

   Pick Hunyuan 3D V3 or Meshy 6, then set generation type, polygon detail, and PBR materials according to your target use. The form shows the credit cost before submission.

3. 3

   AI generates your 3D model

   The selected model analyzes your description and builds a 3D asset with geometry and optional textures. Generation typically takes 30-90 seconds.

4. 4

   Preview, download, and use

   Inspect the result in the browser viewer, then download the GLB file. Import it into Blender, Unity, Three.js, or convert it to STL for 3D printing.

Text to 3D Use Cases

• Game Development

  Generate characters, props, weapons, and environment objects from concept descriptions for Unity, Unreal Engine, or web-based games.

• 3D Printing

  Describe custom figurines, decorative items, or functional prototypes and export a GLB you can convert for your 3D printer.

• AR/VR Content

  Create virtual objects and interactive elements for augmented and virtual reality experiences from text descriptions.

• Product Visualization

  Visualize product concepts before detailed modeling. Generate multiple design variations from text for client presentations and internal reviews.

• Education

  Build 3D teaching aids by describing objects, scientific models, or historical artifacts to make learning more interactive.

Text to 3D Limitations

• Output is GLB only; convert to OBJ, FBX, or STL in your own 3D software when you need other formats.
• Result quality depends on prompt detail - vague prompts produce less accurate geometry.
• Models are static assets; rigging and animation are not generated.
• Generation takes 30-90 seconds and may be longer with high polygon counts or PBR materials.
• Prompt length is limited to 1024 characters on Hunyuan 3D V3 and 600 characters on Meshy 6.
