The Hunyuan 3D Laboratory Tools are a powerful suite of utilities designed to refine, enhance, and prepare your AI-generated 3D models for real-world use. Whether you’re working with high-poly meshes, missing textures, or static characters that need animation, these tools help streamline your workflow directly within the Hunyuan 3D environment.
In this guide, you’ll learn how to use the three main features of the Hunyuan 3D Lab:
- Surface Reduction
- Texture Tools
- Animation Support
We’ll explain what each tool does, why it matters, and how to use it effectively step-by-step.
🧰 What Is the Hunyuan 3D Laboratory?
The Hunyuan 3D Lab is part of the broader Hunyuan 3D ecosystem. It’s a set of post-processing tools available within the interface or programmatically. These tools are designed to optimize the generated 3D assets so they’re ready for use in real-time applications like games, XR, or animation.
🧠 Think of the Lab as your “finishing station” before exporting to Blender, Unity, Unreal, or for 3D printing.
🔻 Surface Reduction: Optimize Without Losing Detail
Hunyuan 3D models often come with high polygon counts to preserve detail and realism. However, for many applications — especially in real-time rendering or mobile — this can be overkill.
✅ Why Use Surface Reduction?
- Reduce file size and rendering cost
- Improve performance in game engines
- Make models compatible with animation or rigging tools
🔧 How to Use Surface Reduction
- Load your model into the Hunyuan 3D Lab interface.
- Click on the “Surface Reduction” tab.
- Select the desired polygon target (e.g., reduce by 50%, 75%, or to a fixed number like 10k triangles).
- Preview the model to ensure surface quality is preserved.
- Click Apply and Export.
🔎 Tip: Avoid over-reduction if you plan to texture or animate the model afterward.
🎨 Texture Tool: Fill in and Enhance Your Models
Some generated models may lack textures or may contain placeholder visuals. The texture tool in the Lab helps you:
- Apply or re-project textures
- Generate UVs if missing
- Enhance color, roughness, or normal details
✅ When to Use It
- Your model lacks color or texture maps
- The UVs are broken or overlapping
- You want to quickly bake new textures onto edited geometry
🔧 How to Use the Texture Tool
- Load your model in the Lab.
- Go to the Texture Tool tab.
- If your model has no UVs, click “Auto Unwrap”.
- Choose Texture Mode: bake from original, paint manually, or retexture.
- Export the model with the new BaseColor, Normal, and Roughness maps.
🎯 Advanced users can export these maps for use in Substance Painter or Blender for further editing.
🕺 Animation Tool: Add Life with Basic Rigging
Hunyuan 3D now supports basic auto-rigging and motion compatibility, making it easier than ever to bring your static characters to life.
✅ What You Can Do
- Automatically add a basic skeleton to a humanoid mesh
- Export to Mixamo or other motion libraries
- Animate inside external software (Blender, Unity, etc.)
🔧 How to Use the Animation Tool
- Open a humanoid model in the Lab.
- Select “Animation” or “Rigging”.
- Confirm the model’s symmetry and orientation.
- The tool will attempt to auto-detect limbs and place a skeleton.
- Export as FBX or GLB with animation-ready rig.
⚠️ Not all models will rig correctly, especially if they are stylized or asymmetrical. Manual adjustment may still be needed in Blender.
💡 Pro Tips for Using the Lab Efficiently
- Always preview changes before final export
- Save a copy of the original high-poly mesh
- Surface Reduction works best after texturing, not before
- Combine the Texture Tool with custom HDRI lighting for better realism
- Use the Animation Tool to prepare characters for Mixamo or mocap workflows
🧾 Final Export Formats
The Lab supports export in multiple formats:
Format | Use Case |
---|---|
.GLB / .GLTF |
Web and AR apps |
.OBJ |
General-purpose, widely supported |
.FBX |
Animation workflows, game engines |
.PLY |
3D printing or scan-related workflows |
🚀 Why the Lab Tools Matter
If you’re planning to use your Hunyuan 3D models in production — especially in games, real-time apps, or film pipelines — the Lab tools are essential. They save time, reduce errors, and ensure your assets are optimized and usable across platforms.
By mastering the Surface Reduction, Texture Tool, and Animation features, you unlock the full power of what Hunyuan 3D can offer.
