Installing ComfyUI

...

with Hunyuan3D Workflow (Automatic Installer)

System Requirements

📌 Operating System:

...

Requirements: You will need a PC with Windows 10 or 11
Hardware: 24 GB ram 📌 RAM: 24GB minimum (32GB recommended so you can run windows apps also) and 6 GB ram Nvidia gpu minimum (8 gb vram to 12 gb vram recommended).If you have less than 8gb vram nvidia card there is a lowvram setting when you start Comfyui. The default is to let it detect vram. 

50 GB disk space in your windows home folder. Later you can moved the installed files to another folder after installation or edit the installer bat file to use another dir. It will be downloading a lot of AI model content to use the 50 GB space so it takes about 2 hours to do the install on a fast internet connection.

for multitasking)
📌 GPU: Nvidia GPU with at least 6GB VRAM (8GB–12GB recommended for best performance)

• If you have less than 8GB VRAM, you can enable the low VRAM mode when launching ComfyUI.
• By default, ComfyUI automatically detects available VRAM.
  📌 Disk Space: 50GB free space in your Windows home folder
• The installation downloads large AI model files (~50GB total), so a fast internet connection is recommended.
• Installation time: ~2 hours (depending on internet speed).
• After installation, you can move the files to another folder or edit the installer BAT file to specify a different directory.

Installation Process

ComfyUI installation involves five main steps. Follow the There are 5 main setup steps in Comfyui. Do steps in order and do not miss any out. All steps are simple to do because the installer does all the hard work.  There are two bat to download and use to do the install. 
ComfyUI3dInstaller.bat  initial install for ComfyUI.
SetupCudaForComfyUI3Dplugin.bat skip any to ensure a successful setup.

💡 Good news! The installer handles all the heavy lifting, so no manual setup is required.

Installation Files

You need to download and run two batch files:

1️⃣ ComfyUI3dInstaller.bat – Runs the initial installation of ComfyUI.
2️⃣ SetupCudaForComfyUI3Dplugin.bat – Sets up the CUDA driver for 3D Python processing (only needs to be run once after the first workflow execution).

Once installed, ComfyUI will be ready for 3D model generation using the Hunyuan3D workflowused once later to setup 3d python CUDA driver when workflow runs.
