ComfyUI Hunyuan3D-1-wrapper

ComfyUI Hunyuan3D-1-wrapper is a custom node that allows you to run Tencent/Hunyuan3D-1 in ComfyUI as a wrapper. !!To avoid breaking your existing environment, it is strongly recommended to use a fresh ComfyUI installation for this node

Setup

Please note that this plugin currently doesn't have an easy way to install in ComfyUI. I'll provide several scenarios for reference.

Additionally, the following environments are all based on Windows 10 + CUDA 12.4 + Python 3.12.

Scenario 1: ComfyUI Bundle(Python 3.12) + 3D Pack

If you downloaded ComfyUI from the ComfyUI Release page (current latest version 0.2.7, bundled with Python 3.12) and have successfully installed 3D Pack, congratulations, you dont need this repo, 3d-pack has its implement already.

Scenario 2: ComfyUI Bundle(Python 3.12)

If you downloaded ComfyUI from the ComfyUI Release page (current latest version 0.2.7, bundled with Python 3.12) but haven't installed 3D Pack, you'll need some additional steps to package related dependencies.

It should be noted that if you plan to use ComfyUI's built-in Python, texture mapping and gif output will not be available in this node.

Package and Install Pytorch3D

Pytorch3D is a major challenge during installation, whether for 3D Pack or this node. Reference steps:

Install C++ build tools locally, and check the following during installation:
Create a Python 3.12 environment using conda:
conda create -n comfy-hunyuan3d-py312-build python=3.12
Activate conda environment:
conda activate comfy-hunyuan3d-py312-build
Install torch:
pip install torch==2.5.1 --index-url https://download.pytorch.org/whl/cu124
Package pytorch3d wheel:
pip wheel git+https://github.com/facebookresearch/pytorch3d If everything goes smoothly, you'll see the pytorch3d wheel file in your current directory
Install pytorch3d wheel using comfyui's bundled python:
{comfyUI_python_embeded}\python -m pip install pytorch3d-0.7.8-cp312-cp312-win_amd64.whl

Install Open3D

Currently, Open3D hasn't released packages for Python 3.12, but you can download the Python 3.12 dev version from their github:

Download the wheel for py3.12+win:
https://github.com/isl-org/Open3D/releases/tag/main-devel
Install local Open3D wheel using comfyui's bundled python:
{comfyUI_python_embeded}\python -m pip install open3d-0.18.0+fcc396e-cp312-cp312-win_amd64.whl

Install Hunyuan3D-1 Node Dependencies

git clone this repository in ComfyUI's custom nodes folder
{comfyUI_python_embeded}\python -m pip install -r requirements.txt
{comfyUI_python_embeded}\python -m pip install git+https://github.com/NVlabs/nvdiffrast
{comfyUI_python_embeded}\python -m pip install Ninja

Again, reminder that in this scenario, texture mapping and gif output are not available.

Scenario 3: Using ComfyUI in Conda Environment (Recommended)

From my personal perspective, this is my most recommended approach, as texture mapping and gif output can be used in this environment. Specific steps:

Install C++ build tools locally, and check the following during installation:
Create a Python 3.12 environment for ComfyUI using Conda:
conda create -n hunyuan3d-comfyui-py312 python=3.12
Activate the environment:
conda activate hunyuan3d-comfyui-py312
Install torch and torchvision:
pip install torch torchvision --index-url https://download.pytorch.org/whl/cu124
Go to ComfyUI's own directory (containing requirements.txt), install ComfyUI's dependencies:
pip install -r .\requirements.txt
pip install git+https://github.com/facebookresearch/pytorch3d
pip install git+https://github.com/NVlabs/nvdiffrast
Download Open3D wheel for py3.12+win:
https://github.com/isl-org/Open3D/releases/tag/main-devel
pip install open3d-0.18.0+fcc396e-cp312-cp312-win_amd64.whl
git clone this repository in ComfyUI's custom nodes folder
Install this repository's dependencies:
pip install -r requirements.txt
pip install Ninja

Run the following command in ComfyUI's root directory to start: python -s main.py --windows-standalone-build

Other Launcher Scenarios (aki, StabilityMatrix, etc.)

I apologize, but I personally don't have the habit of using these launchers. Since different launchers bind to different environments, due to time constraints, I haven't done any testing on them. However, theoretically, they should all work - please research on your own.

Download Checkpoints

Regardless of which scenario you use, after installing the above dependencies, we still need to manually download related checkpoints. Specific steps:

Install huggingface-cli using system environment or Conda python:
pip install "huggingface_hub[cli]"
Ensure the command huggingface-cli is available.
create weights and weights/hunyuanDiT folder.
Run in this node's directory:
huggingface-cli download tencent/Hunyuan3D-1 --local-dir ./weights
and
huggingface-cli download Tencent-Hunyuan/HunyuanDiT-v1.1-Diffusers-Distilled --local-dir ./weights/hunyuanDiT
or if you prefer to run hunyuanDit natively in ComfyUI, download the checkpoint from here, put it into your ComfyUI/models/checkpoints folder.

Runtime

Output path is at ComfyUI/output/Unique3D/Hunyuan3D-1/

Workflow

Here I provide three workflows:

Text to 3D - native example-text2mesh-native for this workflow:

make sure download hunyuanDit checkpoint and put it into checkpoints folder.
keep the negative prompt
keep the last three prompts ,白色背景,3D风格,最佳质量 and add your own prompts before them, for example：a lovely rabbit eating carrots, 白色背景,3D风格,最佳质量

Text to 3D example-text2mesh
Image to 3D example-image2mesh

Please understand the node usage in conjunction with the workflows.

Known issue

Sometimes, ComfyUI will throw the error of torch.OutOfMemoryError: Allocation on device randomly while generating mesh. However, if I run it again several times, then it could generate successfully. You can fix the seed to save time.
