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.
