Key Features of Hunyuan3D

  • Two-Stage Generation Process

    Hunyuan3D utilizes a sophisticated two-stage pipeline:

    • Hunyuan3D-DiT: A model for generating the geometric shape of the 3D asset.
    • Hunyuan3D-Paint: A model responsible for applying high-resolution textures to the generated shapes.

  • Advanced Texturing with Hunyuan3D-Paint

    The Paint module enables high-fidelity texture generation and manipulation:

How to Use Hunyuan 3D-2?

Generating 3D Models

Using Hunyuan 3D-2 is straightforward. You can access it through GitHub or Hugging Face. For this guide, we'll focus on using Hugging Face.

  1. Accessing the Demo: Navigate to the Hunyuan 3D-2 page on Hugging Face and click on the "Demo" button.
  2. Selecting a Model: Choose from the available demos. For example, if you want to generate a Santa model, select it and choose whether you want to generate the shape only or the shape with textures.
    3. Hunyuan 3D-2 interface on Hugging Face
  3. Generating the Model: Once you've made your selection, the tool will wait for GPU availability and begin generating the 3D model. You don't need to log in, but having an account allows you to save your work.
  4. Previewing and Downloading: After generation, you can preview the 3D model and download it for further use in 3D modeling tools like Blender.

Working with Custom Images

Hunyuan 3D-2 also allows you to generate 3D models from custom images. Here's how:

  1. Uploading an Image: Upload a custom image (e.g., a screenshot from the internet).
  2. Setting Parameters: Choose the octree resolution (512, 384, or 256) and enable the "Remove Background" option to focus on the image.
  3. Generating the Model: The tool will generate the 3D model in about 1 to 1.5 minutes.

How to Use Hunyuan3D V2 Locally?

Prerequisites

Before diving into the installation process, you'll need the following tools and software installed on your PC:

1. Python 3.11

Hunyuan 3D-2 requires Python 3.11 for compatibility with PyTorch and CUDA toolkit.

python --version

Download Python 3.11 from the official Python website if needed. Remove other Python versions to avoid conflicts.

2. CUDA Toolkit 12.4

Required for GPU acceleration. Must use CUDA 12.4 for PyTorch compatibility.

nvcc --version

Download CUDA 12.4 from the official NVIDIA website if not installed.

3. PyTorch

Install PyTorch with CUDA support using pip:

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

Verify installation:

python -c "import torch; print(torch.rand(5))"

4. Git

Required for cloning the repository.

git --version

Download from the official Git website if needed.

Setting Up Hunyuan 3D-2

Step 1: Clone the Repository

mkdir hunyuan3d

cd hunyuan3d

git clone https://github.com/tencent/hunyuan3d2.git

cd hunyuan3d2

Step 2: Install Requirements

pip install -r requirements.txt

cd hy3dgen/text_gen_custom_rasterizer

python setup.py install

cd ../differential_renderer

python setup.py install

Step 3: Install Gradio

pip install gradio==3.39

Running Hunyuan 3D-2

Navigate back to the main folder and start the Gradio app:

cd ../../..

python gradio_app.py

Access the interface at http://localhost:8080 in your web browser.

Troubleshooting Tips

  • Ensure Visual Studio Build Tools 2022 is installed for package compilation
  • Verify CUDA version matches PyTorch requirements (12.4)
  • Use Python 3.11 specifically to avoid compatibility issues
