Hunyuan 3D 3.1 is a generative AI tool by Tencent that converts a single 2D image into a production-ready 3D model with 4K PBR textures and clean topology, exportable to GLB and USDZ for use in Unity, Unreal Engine, Blender, and WebXR.
What is Hunyuan 3D 3.1?
Hunyuan 3D 3.1 is an AI-powered 3D generation platform developed by Tencent. It takes a 2D image (JPG, PNG, or WEBP, up to 20MB) as input and outputs a 3D mesh with 4K physically-based rendering (PBR) textures including Albedo, Normal, Roughness, and Metallic maps. The model features clean quad topology and smart UV unwrapping, making it suitable for direct use in game engines, 3D software, and WebXR scenes. The system runs online via a WebUI at vismint.com.
Key Features
- Production Topology — Uses Hunyuan 3.1 optimized topology generation algorithms to produce clean quad meshes, easier for rigging and animation.
- Smart UV Unwrapping — Powered by the 3.1 engine for smart UV unwrapping that significantly reduces stretching and seams, improving texture mapping quality.
- 4K PBR Textures — Supports generation of up to 4K multi-channel PBR materials (Albedo, Normal, Roughness, and Metallic maps) for realistic physical rendering.
- Standard Exports — Natively supports GLB (glTF) and USDZ export, compatible with Blender, Unity, Unreal Engine 5, Three.js, and WebXR.
- Two-Stage Architecture — Leverages Multi-View Diffusion and Sparse View Reconstruction to solve geometric distortion and blurry textures, producing higher-fidelity assets.
- Commercial Licensing — Paid users (Credit Packs or VIP Subscription) can use models commercially; free users can use them for non-commercial projects only.
Who is it for?
- Game developers — Quickly generate 3D props, characters, and environment assets for Unity and Unreal Engine, accelerating prototyping from weeks to minutes.
- E-commerce teams — Create interactive 3D product views from photos for WebXR previews that customers can rotate and explore, boosting conversion.
- Architects and visualization artists — Turn sketches into 3D concept models for early-stage visualization, client presentations, and spatial design ideation.
- Film and animation studios — Generate base meshes and reference models for VFX pipelines; clean topology simplifies retopology and rigging.
What can you do with Hunyuan 3D 3.1?
- Game development: Generate 3D assets from concept art or photos and drag the exported GLB directly into Unity or Unreal Engine.
- E-commerce product display: Upload product photos to create interactive 3D models with PBR materials for web-based product viewers.
- Architecture visualization: Convert sketches or renderings into 3D concept models for client presentations and spatial design.
- Film pre-visualization: Produce reference meshes and base geometry for VFX shots, reducing modeling time during pre-production.
How does it work?
- Upload your image — Upload a photo, concept art, or any 2D image (JPG, PNG, WEBP, up to 20MB).
- AI generates the 3D model — Hunyuan 3D 3.1 analyzes the image using Multi-View Diffusion and Sparse View Reconstruction to produce a high-fidelity mesh with clean topology and 4K PBR textures.
- Download and use anywhere — Export as GLB or USDZ and drag directly into Unity, Unreal Engine, Blender, or any WebXR project.
Pricing
Hunyuan 3D 3.1 offers free and paid tiers. Free users can generate models for personal, non-commercial use. Commercial use requires a paid plan via Credit Packs or VIP Subscription (no dollar amounts stated).
FAQ
Can I use Hunyuan 3D 3.1 online?
Yes, you can generate 3D models online using the WebUI at vismint.com/app. The service offers high-speed cloud generation based on the open-source Hunyuan 3D model.
What 3D formats can I export?
Hunyuan 3D 3.1 exports standard GLB (glTF) and USDZ files, which include geometry, textures, and PBR materials. These are compatible with Blender, Unity, Unreal Engine 5, and Three.js.
Do the models include PBR materials?
Yes, the tool generates PBR-ready textures including Albedo, Normal, Roughness, and Metallic maps for realistic physical rendering.
Can I use generated models for commercial projects?
Commercial use is available for paid users (Credit Packs or VIP Subscription). Free users can only use models for personal, non-commercial projects. See the Terms of Service for details.
Are the models suitable for 3D printing?
Often yes, because the generated meshes are watertight with clean topology. You may need to convert the GLB file to STL or OBJ in Blender or another tool before printing.
