ComfyUI Extension: ComfyUI Hunyuan-3D-2

This is a custom_node for ComfyUI. It converts an image into a 3D file you can import into Blender or whatever 3d software you use. It uses Hunyuan-3D-2 from Tencent.

Make sure you use an image with a transparent background.

This custom node might fail after the first restart. Restart ComfyUI again. Click on the panel ~~☐~~ to look for errors.

If it doesn't install...

Windows

You will need to install Visual C++ build tools

ComfyUI_windows_portable

If you installed ComfyUI with ComfyUI_windows_portable, it is using a version of python which is missing the libs and header files. The way around it is to either copy some folders or install the module from else where. See issue #

Ubuntu

sudo apt install python3-dev libgl-dev

Suse

Hunyuan-3D needs g++ 13, Suse has g++ 14+ by default

sudo zypper install g++-13 Mesa-libGL-devel python3-dev

Usage...

• Example workflow
• When you run it for the first time it will download the models which will take a long time. Press the panel button on the top right ~~☐~~ to see the progress.
• Put the input image into the "input" folder. It must have a transparent background.
• The 3D .glb file is saved in "output" after you run it.

Workarounds...

• If you get a square panel. Make sure you have a transparent background in the image. If the image came from another node, insert an "invert mask" node before giving the mask to this node, some nodes have a mask that's reversed.

Install from git

Not recommended because ComfyUI-Manager will auto update when you press the update button. git will need manual updates for every custom_node you have.

cd custom_nodes
git clone https://github.com/niknah/ComfyUI-Hunyuan-3D-2
pip install -r requirements.txt
cd ComfyUI-Hunyuan-3D-2
git submodule update --init   # You need to get the submodules if you install from git

Other models...

• Right click on the node, click "convert input to widget", "model".

• connect a string node to the "model" input.

• Put in the string node the ID of the model on hugging face. ie. tencent/Hunyuan3D-2

• The big model files are downloaded into ~/.cache/huggingface/hub
