ComfyUI Extension: ComfyUI Hunyuan-3D-2

ComfyUI-Hunyuan-3D-2 Introduction

ComfyUI-Hunyuan-3D-2 is an innovative extension designed to transform 2D images into 3D models, which can be seamlessly integrated into 3D software like Blender. Developed as a custom node for ComfyUI, this extension leverages the power of Hunyuan-3D-2 from Tencent to generate high-fidelity 3D assets. This tool is particularly useful for AI artists who want to bring their digital creations to life in a 3D space, offering a streamlined process to convert images with transparent backgrounds into 3D files.

How ComfyUI-Hunyuan-3D-2 Works

At its core, ComfyUI-Hunyuan-3D-2 uses advanced diffusion models to interpret and convert 2D images into 3D geometry. The process involves two main stages: generating the geometric structure and then applying textures to create a realistic 3D model. The extension uses a flowchart-based interface, allowing users to visually map out the conversion process without needing to write code. This makes it accessible for artists who may not have a technical background but wish to explore 3D modeling.

ComfyUI-Hunyuan-3D-2 Features

• Image to 3D Conversion: Converts images with transparent backgrounds into 3D models, which can be exported in formats like .glb for use in various 3D applications.
• Custom Node Integration: Easily integrates into ComfyUI's node-based system, allowing for flexible and modular workflow designs.
• Error Handling: Provides a panel to check for errors during the conversion process, ensuring smooth operation.
• Model Customization: Users can select different models for conversion, allowing for varied outputs based on the chosen model's characteristics.

ComfyUI-Hunyuan-3D-2 Models

The extension supports multiple models, each tailored for specific types of 3D generation tasks. The main model, Hunyuan3D-DiT-v2-0, is designed for high-resolution geometry generation. Users can switch between models by connecting a string node with the model ID to the "model" input, allowing for experimentation with different styles and outputs.

What's New with ComfyUI-Hunyuan-3D-2

The latest update, version 0.9.4, introduces mini and turbo models, enhancing the speed and efficiency of the conversion process. These models are optimized for faster processing times, making them ideal for quick iterations and testing.

Troubleshooting ComfyUI-Hunyuan-3D-2

Common Issues and Solutions

• Installation Failures: If the extension does not install, ensure that any previous versions are uninstalled using pip uninstall hy3dgen-2.0.0-py3.12.egg.
• Visual C++ Build Tools: On Windows, make sure to install Visual C++ build tools (https://visualstudio.microsoft.com/visual-cpp-build-tools/).
• Python Environment Issues: For ComfyUI installed with ComfyUI_windows_portable, ensure the correct Python libraries and headers are available. Refer to issue #3 for more details.
• Attribute Errors: If encountering has no attribute '_get_vc_env', downgrade setuptools with pip install setuptools==75.8.2.

FAQs

• Why is my 3D model not appearing correctly? Ensure the input image has a transparent background and check for any error messages in the panel.

• How do I change the model used for conversion? Right-click on the node, select "convert input to widget", and connect a string node with the desired model ID.
