What is Hunyuan 3D?
Hunyuan 3D on 3d-models.hunyuan.tencent.com is an AI‑powered 3D asset generation platform from Tencent that lets users create high‑quality 3D models from text, images, or sketches. The system uses diffusion‑based models with dedicated text and image encoders plus a 3D decoder to turn prompts into detailed meshes with PBR materials, supporting multimodal inputs and professional export formats like OBJ, GLB, and FBX. It is designed for both one‑off creative experiments and production pipelines, enabling rapid prototyping without requiring traditional modeling skills.
Key features include text‑to‑3D, image‑to‑3D, and sketch‑to‑3D workflows, multi‑view geometry reconstruction, and smart topology optimization for efficient meshes. The platform also supports high‑resolution outputs suitable for game assets, VR environments, e‑commerce visualizations, 3D printing, and film/animation pipelines, with integration paths into engines such as Unity, Unreal, and Blender through its web‑based interface and API.
Hunyuan 3D targets indie developers, students, hobbyists, and small to mid‑sized studios that want to accelerate 3D content creation without deep 3D software expertise. It is especially useful for teams iterating rapidly on characters, props, environments, and product visualizations, while also appealing to researchers and developers who can access the underlying open‑source models on GitHub and Hugging Face to extend or customize the system.
Hunyuan 3D pricing
Pricing model: Freemium
Users of the Hunyuan 3D system receive a free daily quota of 20 generations through the global web platform, allowing casual creators to experiment without cost. Enterprise users can access the Hunyuan 3D Model API via Tencent Cloud, which includes 200 free credits for generating 3D assets under that plan before additional usage becomes paid. Specific paid tiers and subscription details for higher‑volume or commercial workloads are defined in Tencent Cloud’s pricing section for the Hunyuan 3D API and are not fully enumerated in the public project pages, so volume‑based or enterprise pricing varies by contract and usage tier.

Frequently asked questions about Hunyuan 3D
What is Hunyuan 3D and what does it do?
Hunyuan 3D is Tencent’s AI‑driven 3D content creation engine that generates high‑quality 3D models and scenes from text, images, or sketches. It runs as a diffusion‑based large model with text and image encoders feeding a 3D decoder that produces meshes with PBR materials, targeting use cases such as game assets, VR environments, e‑commerce visualization, and 3D printing while supporting export to common formats like OBJ and GLB.
What inputs can I use to generate models on Hunyuan 3D?
You can generate models using natural language text descriptions, single or multi‑view reference images, and simple sketches paired with text attributes such as color, material, and category. The system supports single‑view generation for quick concepts as well as multi‑view image inputs for more accurate geometry reconstruction, enabling diverse creative workflows without requiring pre‑existing 3D assets.
What export formats does Hunyuan 3D support?
Hunyuan 3D outputs models in mainstream 3D formats such as OBJ, GLB, and FBX, which are compatible with major game engines and 3D software like Unity, Unreal, and Blender. These formats preserve meshes and PBR materials so assets can be directly imported into production pipelines for further editing, animation, or rendering.
Is Hunyuan 3D free to use?
The Hunyuan 3D web platform offers a free tier that grants 20 daily generations for individual users, making it accessible for students, hobbyists, and small studios. Additional or higher‑volume usage through the Hunyuan 3D Model API on Tencent Cloud is governed by enterprise‑style pricing, where paid plans unlock higher quotas and preferential rates for commercial projects.
Can I integrate Hunyuan 3D into my own tools or pipeline?
Yes, Tencent provides a Hunyuan 3D Model API via Tencent Cloud that lets developers integrate 3D generation capabilities into custom applications, editors, or internal production pipelines. Developers can also access open‑source model weights and code on GitHub and Hugging Face to build or extend tools that consume Hunyuan 3D directly, enabling deep integration into existing workflows.
What types of 3D content is Hunyuan 3D best suited for?
Hunyuan 3D excels at creating characters, props, vehicles, furniture, architectural elements, product models, and environmental assets suitable for games, VR, AR, film previs, and 3D printing. The system handles both hard‑surface and organic shapes with consistent textures, making it useful for rapid prototyping and asset iteration across multiple media.
Does Hunyuan 3D support animation or rigging?
The core Hunyuan 3D platform focuses on geometry and material generation rather than full animation or rigging; however, some character‑oriented workflows on affiliated Tencent pages allow basic animation triggering after generation. For complete animation and rigging, the exported models are typically imported into dedicated DCC software such as Blender, Maya, or MotionBuilder for further setup.
How does Hunyuan 3D handle multi‑view images?
Hunyuan 3D can accept multiple reference viewpoints (such as front, side, back, and top) to reconstruct more accurate 3D geometry by aligning those views into a coherent mesh. The system then synthesizes textures that wrap consistently across surfaces, reducing distortions and improving fidelity compared to single‑view generation.
Is Hunyuan 3D open‑source?
Key components of the Hunyuan 3D series, including Hunyuan3D‑2 and related models, are open‑source and available on GitHub and Hugging Face, with weights, inference code, and mesh export tools. The web platform and API on 3d-models.hunyuan.tencent.com and Tencent Cloud provide managed access and additional services built on top of these open models.
What are the limitations on complexity or size of generated models?
Hunyuan 3D applies practical limits on polygon count and voxel resolution to ensure generation speed and stability, which means extremely dense or highly complex scenes may require simplification or post‑processing. Fine control over mesh density and topology is constrained, so artists often refine the generated meshes in external tools when pushing into high‑end production or 3D printing workflows.
