Installation Process (new Windows installer uptodate)
Follow this new guide to install the latest version of comfyui. It also has an easier process to install compared to the bat installer i created below.
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.
