Tencent Hunyuan 3D

Site Overview

Tencent Hunyuan 3D (3d.hunyuan.tencent.com) is Tencent's self-developed AI 3D generation platform. Enter text, images, or sketches, and within minutes you can produce figurine-grade 3D models without learning Blender from scratch. It covers text-to-3D, image-to-3D, sketch-to-3D, and also supports a 3D world model and the Hunyuan 3D Studio professional workstation.

Core Features

1. AI Creation: Text-to-3D / Image-to-3D / Sketch-to-3D

On the homepage, select AI Creation with three input methods:

• Text-to-3D: Write a prompt, such as "a steampunk mechanical dolphin with gears," and directly generate a model.
• Image-to-3D: Upload 2–4 multi-view images (Studio 1.2 supports eight-view), restoring geometry and materials.
• Sketch-to-3D: A simple drawing plus text description of color and category turns 2D into 3D.

The underlying Hunyuan 3D 3.1 model supports PBR materials and custom polygon counts, with output in OBJ, GLB and other formats, importable into Unity, Unreal, and Blender.

2. Hunyuan 3D Studio: Full-Pipeline Professional Workstation

Studio is aimed at 3D designers and game developers, covering concept design → geometry modeling → texture painting → component splitting → rigging and skinning → animation. Currently, the Character and Prop modules are open, with Map/Level coming soon. PartGen 1.5 supports brush interaction for component splitting, making reuse for 3D printing more convenient.

3. Hunyuan World Model (HunyuanWorld)

The World Model takes a different route: input text or images to generate walkable 3D scenes (3DGS/Mesh), supporting free movement, physical collisions, and a character adventure mode. It is suitable for game level prototyping, virtual production, and digital twins. HY-World 2.0 has been open-sourced, with the paper and weights publicly available.

4. Intelligent Topology + Post-Processing Toolchain

It is not just "generate a model"—it also provides post-processing APIs such as intelligent topology (automatic decimation and retopology), texture generation, UV unwrapping, component generation, text-to-animation, rigging and skinning, and format conversion. Enterprises can integrate it into their own production pipelines via the Tencent Cloud Hunyuan 3D API.

Pricing Model

API Credit Pricing (official billing documentation):

Prepaid credit packages: 1,000 credits for ¥100; 10,000 credits for ¥980; 50,000 credits for ¥4,750.

Free quota examples:

• Web: 20 times/day ≈ enough for personal trial and light creation
• API 100 credits ≈ about 5 times of Pro generation with texture (20 credits/use)
• Failed generations do not deduct credits

Pricing may change; please refer to the official website and Tencent Cloud billing page.

Comparison with Similar Platforms

Unique Advantages

1. Strong open-source ecosystem—over 3 million downloads on Hugging Face, highly recognized by the developer community.
2. Four product lines: Web + Studio + World Model + API, covering everything from personal trial to enterprise integration.
3. Full-pipeline Studio covers rigging, animation, and component splitting, not just "producing a model."

Practical Highlights

• Stable domestic access and good understanding of Chinese prompts.
• Supports PBR materials and eight-view input, practical for gaming and 3D printing scenarios.
• Export formats directly integrate with Unity / UE / Blender.

Objective Limitations

1. The web version's 20 times/day free quota runs out quickly for heavy users.
2. API is billed per use, and batch production costs are not low (concurrency add-on packages at ¥30,000 per concurrency/month).
3. AI-generated model details and topology still require manual fixing; complex character rigging cannot fully replace professional workflows.

Side-by-Side Comparison

FAQ

1. What does Hunyuan 3D do?
Tencent's AI 3D modeling platform. It uses text, images, or sketches to generate 3D models, and can also generate walkable 3D scenes. It is aimed at game developers, 3D designers, e-commerce 3D displays, and 3D printing enthusiasts.

2. Is it really free?
The web version offers 20 free generations per day, and Studio is free to experience during the public beta. Beyond the quota or via API, it is billed by credits.

3. What is the relationship with the Hunyuan 3D API?
Same model family, two ways to use it. The web/Studio is for creators doing manual operations; the Tencent Cloud API is for developers making programmatic calls, billed by credits, and needs to be activated separately.

4. Can generated models be used commercially?
You must comply with Tencent Hunyuan 3D's User Agreement and content safety policies. The international version promotes commercial-grade 3D assets, but the specific authorization scope is subject to official terms. It is recommended to confirm the latest agreement before commercial use.

5. How do I export to Unity / Blender?
After generation, preview it online, then download OBJ, GLB and other formats and import them directly into Unity, Unreal Engine, or Blender. The API can also specify output format (at extra credit cost).

6. What is the difference between Studio and regular AI Creation?
AI Creation is a quick one-shot generation; Studio is a professional workstation supporting concept design, multi-view, texture painting, component splitting, rigging and skinning, and other full-pipeline processes. For character/prop assets, Studio is recommended.

7. How is the World Model different from regular 3D generation?
Regular 3D generates a single object model (figurine, prop); HunyuanWorld generates an explorable 3D scene/world with walking, collision, and character modes.

8. How many uses does 100 API credits give?
The Pro version defaults to 20 credits/use (text/image-to-3D with texture), so 100 credits is about 5 uses. Adding PBR, multi-view, custom polygon counts, etc., will stack additional consumption. Failed generations do not incur charges. For heavy use, purchasing credit packages is recommended.
