Hunyuan 3D V3.1

Hunyuan 3D 3.1: 8-View Reconstruction With Better Geometry and Texture

Hunyuan 3D 3.1 (catalog slug hunyuan3d-v3-1) is Tencent's upgraded 3D generation model, launched globally in January 2026 - the version that took Hunyuan 3D's quality another step with 8-view reconstruction.

Here's the short version: 3.1 improves geometry precision and texture fidelity over 3.0, supports up to 8-view input, and optimizes the full pipeline - components and topology - for production use. It is available on Tencent Cloud's HY 3D API and the global 3d.hunyuanglobal.com platform, with free daily generations for consumers. The honest caveats: it is a hosted service, and quality gains over 3.0 are best judged on your own assets.

1. Model Overview

Tencent rolled out Hunyuan 3D 3.1 in January 2026 as the quality upgrade to the 3.0 generation. The two headline changes: up to 8-view input for reconstruction, and improved geometry precision plus texture fidelity. The release also optimized the full pipeline - components and topology - so outputs slot into production workflows more cleanly.

The model went live on Tencent Cloud's HY 3D API and the global 3d.hunyuanglobal.com platform, with a free daily generation quota for consumer testing.

2. Core Features

8-view reconstruction. More angles, better fidelity.

Geometry precision. Improved shapes and proportions.

Texture fidelity. More faithful surface detail.

Pipeline optimization. Components and topology.

API access. HY 3D API model 3.1.

Global platform. 3d.hunyuanglobal.com.

Consumer quota. Free daily generations.

3. Technical Specifications

Note: export formats, quotas, and pricing follow Tencent Cloud docs.

4. Capability Comparison

Reading the table honestly: 3.1 is the refinement release - same service, better reconstruction fidelity and production fit.

5. Core Advantages

1. 8-view fidelity. The defining upgrade.
2. Better geometry and texture. Direct quality gains.
3. Production pipeline. Component and topology optimization.
4. Global + API. Consumer and developer access.
5. Free daily quota. Low-friction evaluation.

6. Recommended Use Cases

• Asset reconstruction: 8-view product and object models.
• Game production: cleaner topology and components.
• E-commerce: high-fidelity product 3D.
• Creative pipelines: texture-accurate assets.
• Evaluation: free daily quota testing.

7. Example Prompts

1. 8-view reconstruction

2. Production asset

3. Sketch upgrade

8. Selection Recommendations

Choose Hunyuan 3D 3.1 if:

• 8-view reconstruction fidelity is the requirement.
• You want the latest geometry and texture quality.
• Pipeline fit (topology, components) matters.

Choose 3.0 if:

• Your pipeline is validated on it and 8-view input is unnecessary.

9. The Bottom Line

Verdict: The upgrade that made Hunyuan 3D a serious reconstruction tool. Hunyuan 3D 3.1's 8-view input, better geometry, and texture fidelity - plus full pipeline optimization - make it the version to use for production assets. It is hosted, and quality is judged per asset, but for API-driven 3D reconstruction in 2026, 3.1 is the strongest Tencent option.
