Tencent’s Hunyuan3D platform (https://3d-models.hunyuan.tencent.com/) brings the power of generative AI to every step of the 3D-asset pipeline. Whether you’re a game designer, filmmaker, product modeller, or hobbyist creator, Hunyuan3D offers a suite of tools that let you go from concept to production–ready models in seconds.
Key Features
- Text-to-3D (文生3D)
- Describe your object in natural language—English or Chinese—and the platform instantly generates up to four high-quality 3D meshes.
- Supports style and material keywords, so you can specify “low-poly fantasy castle” or “photorealistic wooden chair.”
- Image-to-3D (图生3D)
- Upload one or more reference images; Hunyuan3D uses advanced diffusion-based encoding to reconstruct accurate geometry and textures.
- Ideal for turning concept art or real-world photos into fully textured, riggable models.
- Sketch-to-3D
- Upload a line drawing or thumbnail sketch and add a brief text description (e.g., “organic sci-fi helmet”).
- The engine interprets both form and intent, delivering a 3D prototype ready for refinement.
- PBR Texture Generation & Custom Materials
- Generate physically based rendering (PBR) textures—albedo, normal, roughness, and metallic maps—in a single pass.
- Choose from a library of material styles or provide your own reference photo for bespoke textures.
- 3D Animation & Rigging
- Automatically bind skeleton rigs to character models and apply motion templates (walk, run, jump, etc.).
- Export FBX/GLTF with baked animations for seamless integration into game engines or compositing tools.
- Workflow Templates & Low-Polygon Optimization
- Select from production-ready pipelines (e.g., game-engine-optimized low-poly, film-quality high-poly).
- Smart decimation automatically reduces mesh complexity while preserving silhouette and detail.
How It Works
Under the hood, Hunyuan3D leverages a two-stage diffusion framework:
- Hunyuan3D-DiT generates coarse geometry across multiple views, ensuring solid topology.
- Hunyuan3D-Paint then synthesizes high-resolution texture maps that align perfectly with the mesh.
The end-to-end process—from input (text, image, or sketch) to exportable 3D asset—takes as little as 30 seconds on a modern GPU.
Getting Started
- Visit the platform at https://3d-models.hunyuan.tencent.com/
- Sign up or log in with your Tencent Cloud account.
- Choose your input modality (Text, Image, Sketch).
- Enter your prompt details and select any style/material preferences.
- Click “Generate” and download your 3D model in the preferred format.
Hunyuan3D also offers an open-source repository (v2.1) on GitHub for developers who want to run models locally, fine-tune on custom datasets, or integrate the API into their own pipelines.
Applications & Use Cases
- Game Development: Rapid prototyping of characters, environments, and props with ready-to-import assets.
- Film & Animation: Generate background set extensions or crowd-character rigs with minimal manual modelling.
- Product Design: Visualize new designs in 3D, iterate textures/materials, and export CAD-compatible meshes.
- Education & Research: Use the open-source models to study generative diffusion techniques in 3D.
With its blend of cutting-edge research and production-grade tooling, Tencent Hunyuan3D is set to democratize 3D creation—lowering the barrier to entry and accelerating creativity across industries.
