Hunyuan3D V3.1 Pro

Model Information

Display Name: Hunyuan3D V3.1 Pro

API Model ID: tencent/hunyuan3d-v31-pro

Category: Image To 3D

Description: Hunyuan3D V3.1 Pro is Tencent's latest professional-grade 3D generation model, an evolution of the Hunyuan3D V3 architecture with enhanced spatial accuracy and reduced geometric artifacts. It generates high-quality 3D assets in GLB format from one or more reference images, supporting both single frontal image and 8-view multi-view reconstruction. ## Key Features - **Enhanced 8-view reconstruction** — supports single frontal image or full 8-view multi-view set (front, left, right, back, top, bottom, left_front, right_front) - **Clean topology** — produces watertight meshes with improved spatial accuracy - **PBR material support** — optional physically-based rendering materials for realistic lighting - **Flexible polygon count** — configurable from 3,000 to 1,500,000 faces depending on detail requirements - **Multiple generation modes** — Normal (textured) or Geometry (texture-free white model) - **GLB output** — industry-standard binary glTF format with geometry, textures, and materials ## Best Use Cases - Game asset creation — characters, props, and environment objects - E-commerce product visualization and 3D previews - AR/VR content development - Architecture and interior design mockups - 3D printing preparation - Film and animation pre-visualization ## Parameters | Parameter | Type | Required | Default | Description | |-----------|------|----------|---------|-------------| | images | URL[] | Yes | — | 1 to 8 reference images (single front view or 8-view multi-view set) | | prompt | string | No | — | Text description to guide generation (up to 1024 chars) | | generate_type | string | No | Normal | Normal (textured) or Geometry (white model) | | enable_pbr | boolean | No | false | Enable PBR material generation | | face_count | integer | No | 500000 | Polygon count (3,000–1,500,000) | ## Pricing Base cost per generation is /bin/bash.4875 (Normal mode).

About

Hunyuan3D V3.1 Pro is Tencent's latest professional-grade 3D generation model, an evolution of the Hunyuan3D V3 architecture with enhanced spatial accuracy and reduced geometric artifacts. It generates high-quality 3D assets in GLB format from one or more reference images, supporting both single frontal image and 8-view multi-view reconstruction.

Key Features

  • Enhanced 8-view reconstruction — supports single frontal image or full 8-view multi-view set (front, left, right, back, top, bottom, left_front, right_front)
  • Clean topology — produces watertight meshes with improved spatial accuracy
  • PBR material support — optional physically-based rendering materials for realistic lighting
  • Flexible polygon count — configurable from 3,000 to 1,500,000 faces depending on detail requirements
  • Multiple generation modes — Normal (textured) or Geometry (texture-free white model)
  • GLB output — industry-standard binary glTF format with geometry, textures, and materials

Best Use Cases

  • Game asset creation — characters, props, and environment objects
  • E-commerce product visualization and 3D previews
  • AR/VR content development
  • Architecture and interior design mockups
  • 3D printing preparation
  • Film and animation pre-visualization

Parameters

ParameterTypeRequiredDefaultDescription
