This is a link to an advanced Comfyui with Hunyuan-3d-2 Youtube tutorial. Its excellent as it shows Comfyui in use, It starts with manual install of comfyui (skip that as you can use the installer here) and then the tuturial shows how to improve the model generation quality with a custom workflow to produce much higher quality textures, texture paint in blender, retopologise using quad remesher and then bake the texture to the model to have a lower poly game ready model.

- If you have less than 8GB VRAM, you can enable the low VRAM mode when launching ComfyUI.
- By default, ComfyUI automatically detects available VRAM.

Installation Process (new Windows installer uptodate)
Follow this new guide to install the latest version of comfyui. It also has an easier process and more sophisticated windows installer compared to the bat installer i created below. It automates the same install process but uses a newer version of Comfyui and Hunyuan 3d-2.
The steps I did for a fresh install is to run the installer let to download fully and wait for the message 'all startup tasks have been completed'. then https://github.com/YanWenKun/ComfyUI-Windows-Portable Download the two zip files. Download the models and place in the dir as noted after you run the installer that creates the empty model dirs.
1) copy all the files in dir ExtraScripts to one dir up so you can run_nvidia_gpu.bat to start ComfyUI. (you cant start comfyui with run_nvidia_gpu.bat in the ExtraScripts dir but it works one dir up)
2) Manager button. Press Update Comfyui and restart then refresh the webpage.
3) install two custom nodes using Manager button and Custom Nodes Manager: ComfyUI Hunyuan-3D-2 and ComfyUI-ComfyUI-Hunyuan3DWrapper.
4) In CMD terminal go to root dir and run: .\python_standalone\python.exe -m pip install "Comfyui\custom_nodes\comfyui-hunyan3dwrapper\wheels\custom_rasterizer-0.1.0+torch260.cuda126-cp312-cp312-win_amd64.whl"
5) From Comfyui web interface menu (top left) Workflow/Open to load workflow in the ComfyUI\custom_nodes\comfyui-hunyan3dwrapper\example_workflows\hy3d_example_01.json.
6) Top left on the now loaded worflow open image button and choose the penguin found in the example_workflows dir from the last step you did.
7) Press the blue button RUN located at the bottom of the workflow. Wait a few mins for models to download and the 3d penguin should appear bottom right.
Installation Process (old version)
ComfyUI installation involves five main steps. Follow the steps in order and do not skip any to ensure a successful setup. The install guide details via screenshots every step.
