Setting up Hunyuan3D-2 locally on a Windows machine involves several steps, including meeting system requirements, installing necessary software, and configuring the environment for optimal performance. This guide provides a comprehensive walkthrough to ensure a successful installation and setup of the Hunyuan3D-2 model.

What is Hunyuan3D-2?

Hunyuan3D-2 is an advanced AI model developed by Tencent that converts 2D images into high-resolution 3D models. It leverages diffusion models for shape generation and texture synthesis, making it a powerful tool for artists, designers, and developers looking to create 3D assets from 2D images.

System Requirements

Ensure your system meets the following requirements before proceeding:

• Operating System: Windows 10 or later
• Processor: Intel i5 or higher (i7 or better recommended)
• RAM: Minimum 16GB (32GB recommended)
• GPU: NVIDIA GPU with at least 6GB VRAM (8GB+ recommended for texture generation)
• GPU Driver: Version newer than March 2024 (version >550)
• Storage: At least 50GB free space for model files and dependencies

Software Requirements

To run Hunyuan3D-2, install the following software:

1. Python (Version 3.11 or later)
2. CUDA Toolkit (Version 12.4 or later)
3. Visual Studio Build Tools (For compiling C++ components)
4. PyTorch (Compatible with your CUDA version)

Installation Guide

Step 1: Install Python

1. Download Python from the official website.
2. Run the installer and check "Add Python to PATH."

Verify installation:

python --version

Step 2: Install CUDA Toolkit

1. Download the latest CUDA Toolkit from the NVIDIA website.
2. Follow the installation instructions.

Verify CUDA installation:

nvcc --version

Step 3: Install Visual Studio Build Tools

1. Download Visual Studio Build Tools.
2. Select "Desktop development with C++" during installation.

Step 4: Install PyTorch

1. Visit PyTorch’s website to select the correct installation command.

Install via pip:

pip install torch torchvision torchaudio --extra-index-url https://download.pytorch.org/whl/cu124

Step 5: Download Hunyuan3D-2

Navigate into the directory:

cd Hunyuan3D-2

Clone the repository:

git clone https://github.com/tencent/Hunyuan3D-2.git

Step 6: Install Required Python Packages

Run the following command:

pip install -r requirements.txt

Step 7: Setup Texture Generation (Optional)

Run the setup script:

python setup.py install

Navigate to the texture generation directory:

cd hy3dgen/texgen/custom_rasterizer

Step 8: Download Model Files

1. Return to the main directory of Hunyuan3D-2.

Execute the script to download models:

.\2-download-models.bat

(This process may take some time as it downloads approximately 26GB of model data.)

Step 9: Running Hunyuan3D-2

1. If you encounter an "EP Error," it can be ignored as it typically indicates a fallback to CUDA.

Run the application:

.\3-run.bat

Step 10: Accessing the Web Interface

Open your browser and go to:

http://localhost:8080/

This will bring up the Hunyuan3D interface where you can start generating 3D models.

Troubleshooting Common Issues

• Insufficient VRAM: If your GPU has limited VRAM, use run-very_low_vram.bat for optimized memory usage.
• Dependency Errors: Ensure all required dependencies are installed by checking requirements.txt.
• CUDA Errors: Update your GPU drivers and verify compatibility with your CUDA version.

Conclusion

Setting up Hunyuan3D-2 locally on Windows is straightforward if you carefully follow these steps. With the right configuration, you can fully utilize its capabilities for creating stunning 3D models from simple 2D images.

By ensuring that your system meets the requirements and proceeding through each step methodically, you’ll be able to explore all the features of Hunyuan3D-2 effectively, whether for personal projects or professional use in design and development environments.

With advancements in AI technology like Hunyuan3D-2, transforming creative visions into reality has never been easier!
