Hunyuan 3D Engine Global Launched: An AI 3D engine for creators worldwide

1. Abstract

Hunyuan 3D Engine Global is an AI 3D creation engine launched by Tencent's Hunyuan team for the world, based on the self-developed Hunyuan3D large model family and cloud API services. The platform supports direct generation of high-quality 3D models from text, images, and sketches, compressing asset production that traditionally takes days or even weeks to the minute level. Many of the Hunyuan3D models behind it have been open-sourced or partially open on Hugging Face and GitHub, taking into account the ease of use of cloud services and community scalability.

2. Core features

1. Multimodal input: Support Text-to-3D, Image-to-3D (including multiple views), Sketch-to-3D, and some scene/character editing capabilities.
2. 3D-DiT hierarchical engraving: Adopting a layered 3D-DiT "sculpting" generation process, first thick and then thin, the official disclosure has improved the modeling accuracy by about 3 times in the 3.0 generation model, up to 1536³ voxel-level resolution.
3. Geometry-texture decoupling: The cloud engine uses a large model architecture for geometry and texture decoupling, supports high-precision geometry and high-resolution texture maps, and generates editable PBR textures.
4. Friendly engineering integration: Output standard OBJ/GLB and other formats, compatible with mainstream engines and DCC tools such as Unreal Engine, Unity, Blender, etc., suitable for direct entry into the production line.
5. Open source model ecosystem: Provide open source repositories such as Hunyuan3D-1, Hunyuan3D-2/2.1, HunyuanWorld-1.0, Hunyuan3D-Part, and Hunyuan3D-Omni, covering object-level to world-level generation, component segmentation, and controllable generation.

3. Installation

1. Access the cloud authoring platform

1. in the browser 3d.hunyuanglobal.com and log in with your email address or Tencent Cloud International Station account.
2. Select Text / Image / Sketch mode in the interface, enter prompts or upload images, and you can generate 3D models online; By default, new users can generate quotas for free about 20 times per day (please refer to the official website for details).

1. API access (enterprises and developers)

1. Open the tencentcloud.com/products/ai3d and create or log in to your Tencent Cloud International account.
2. After receiving 200 free trial points, activate the Hunyuan 3D Global service in the console and create a key.
3. Embed 3D generation capabilities into games, design tools, or business systems by calling interfaces using REST APIs or SDKs (e.g., Python/Java) as per official documentation.

1. Local open source deployment (optional advanced)

1. Clone repositories such as Hunyuan3D-2.1, HunyuanWorld-1.0 and other repositories from GitHub, and configure Python, CUDA, and dependency environments according to the README.
2. Download the corresponding weights and sample data, and run Text-to-3D / Image-to-3D inference using the command line or Gradio Web UI.
A
3. GPU with a certain amount of video memory is required, depending on the size and resolution of the model selected.

4. Typical Use Cases

1. Game and XR Development: Quickly generate white models of characters, props, and levels, and import them into Unreal/Unity for detailed modeling, animation, and lighting.
2. E-commerce and advertising creativity: Generate 3D models based on product images or copy for 360° rotation displays, AR pilots, or interactive advertising.
3. Film and animation previews: produce low/medium precision assets and preview scenes, and accelerate storyboarding, lighting solutions, and lens design.
4. 3D printing and maker projects: After generating high-precision geometric models, they are re-topology and structure reinforced, and then output as print-friendly meshes.
5. Education and scientific research: Used to visualize complex structures (such as architecture, machinery, biomorphism), or as a data source for 3D perception, reconstruction, and generation tasks.

5. Ecology and competing products

1. Ecological aspect: on the one end is 3d.hunyuanglobal.com and Tencent Cloud International Edition API, and on the other end are open source repositories such as Hunyuan3D-1/2.x, World-1.0, Part/Omni and Hugging Face models, plus the domestic mixed element 3D creation platform and Studio workbench, forming " Cloud service + local open source + industry integration".
2. Comparison of competitors: In the field of cloud 3D generation, platforms such as Tripo, Meshy, Trellis, and Rodin can be analogized; In terms of open source models, it competes with research-based models such as Rodin and Stable-3D. Hunyuan 3D is characterized by a complete model family system, a high degree of open source, and has been implemented in China's local games, e-commerce, 3D printing and other industries. The actual effect and cost still need to be compared and tested in combination with their own projects.

6. Limitations and Precautions

1. The generated results are not "plug and play": complex assets usually still need to use tools such as Blender and Maya for topology optimization, normal repair, UV and material refinement before entering production.
2. Computing power and cost: Ultra-high resolution (such as 1536³) or world-class scene generation consumes a lot of GPU/cloud resources, so it is recommended to reasonably control the resolution and number of iterations according to the needs of the scenario.
3. Authorization and compliance: The license agreements of cloud APIs and each open source model are not exactly the same, and you need to read the license and Tencent Cloud service terms separately before commercial use, and pay attention to the constraints on data security, copyright, and content responsibilities.
4. Version differences: The model versions used in international stations, domestic platforms and open source repositories may be different (such as 2.1, 3.0, World-1.0, etc.), and the effects and functions will be different.

8. FAQs

Does Hunyuan 3D Global support fully offline/on-premises deployment?

Currently, both the International Station and Tencent Cloud API are cloud services and do not support offline deployment. However, the team has open-sourced a number of Hunyuan3D models, and developers can deploy inference services locally or on their own clouds, and the functionality and performance may differ from the commercial cloud version.

Is Hunyuan 3D API available in commercial projects?

The official positioning is aimed at commercial scenarios such as gaming, e-commerce, and advertising, and commercial integration is generally allowed, but it must comply with Tencent Cloud's AI3D product agreement and local laws and regulations. For highly sensitive industries (such as finance and healthcare), it is recommended to confirm with Tencent Cloud Business or Legal Affairs first.

Can the generated 3D models be imported directly into Unreal, Unity, and Blender?

The engine supports output standard formats such as OBJ/GLB and can be recognized by mainstream game engines and DCC tools. However, for stable rendering and physics, it is still recommended to perform topology checks, normal/tangent repairs, and material tuning after import.

What is the difference between 20 free credits on the web and 200 credits on the API?

The web creation platform is aimed at individuals and lightweight creators, with about 20 free generations per day, mostly for experience and small-scale creation; The 200 points on the API side are the trial quota for enterprise-level or developer integration, which is mainly used to verify the call process and effect, and then pay according to the official billing policy.
