Introduction
This is an addon for using ComfyUI in Blender.
ComfyUI : It will convert ComfyUI nodes into Blender nodes, letting you use ComfyUI inside Blender without having to switch between programs.
Blender : Based on ComfyUI, you can directly generate AI full angle materials, use cameras as real-time input sources, and combine with other ComfyUI custom nodes to achieve functions such as AI animation interpolation and style transfer.
(My dream: I hope Blender and ComfyUI can fight side by side in the future ദ്ദി˶>𖥦<)✧ )

Installation
WINDOWS 10\11
- Install Blender
First, you need to install Blender(We recommend Blender 3.5, 3.6.X, or 4.0).
- Install this add-on（ComfyUI BlenderAI node）
- Install from Blender's preferences menu
In Blender's preferences menu, under addons, you can install an addon by selecting the addon's zip file. Blender will automatically show you the addon after it's installed; if you missed it, it's in the Node category, search for "ComfyUI". Don't forget to enable the addon by clicking on the tickbox to the left of the addon's name!
Note: The zip file might not have a preview image. This is normal.
- Install manually (recommended)
This is a standard Blender add-on. You can git clone the addon to Blender's addon directory:
cd %USERPROFILE%\AppData\Roaming\Blender Foundation\blender\%version%\scripts\addons
git clone https://github.com/AIGODLIKE/ComfyUI-BlenderAI-node.git --recursive
Then you can see the addon after refreshing the addons menu or restarting Blender. It is in the Node category, search for "ComfyUI". Don't forget to enable the addon by clicking on the tickbox to the left of the addon's name!
3.AI material generation (Baking requires the use of the add-on EasyBakeNode)
-
Install the add-on EasyBakeNode
-
Your ComfyUI is working properly
-
You need to download Controlnet model (At least download the following ones)and install comfyui controlnet aux
Linux
If you're using Linux, assuming you have some experience:
- Install Blender
- Create and activate a Python venv
- Install ComfyUI
cd /home/**YOU**/.config/blender/**BLENDER.VERSION**/scripts/addonsgit clone https://github.com/AIGODLIKE/ComfyUI-BlenderAI-node.git --recursive- Set your ComfyUI path and your venv /bin/ path in the addon's preferences
Some things will not work on Linux, or might break!
Usage
- Prepare ComfyUI
You can download ComfyUI from here: ComfyUI Releases
Or you can build one yourself as long as you follow this path structure:
├── ComfyUI
│ ├── main.py
│ ...
├── python_embeded
│ ├── python.exe
│ ...
- Set the "ComfyUI Path" to your ComfyUI directory
- Set the "Python Path" if you're not using the standard ComfyUI file directory
The default (empty) path is:
├── ComfyUI
├── python_embeded
│ ├── python.exe <-- Here
If you're using a virtual environment named venv, the executable is in venv/Scripts/python.exe.
- Open the ComfyUI Node Editor
Switch to the ComfyUI Node Editor, press N to open the sidebar/n-menu, and click the Launch/Connect to ComfyUI button to launch ComfyUI or connect to it.
Or, switch the "Server Type" in the addon's preferences to remote server so that you can link your Blender to a running ComfyUI process.
- Add nodes/presets
Like in the other Node Editors, you can use the shortcut Shift+A to bring up the Add menu to add nodes. You can also click on the "Replace Node Tree" or "Append Node Tree" buttons in the sidebar to add/append a node tree.
For image previews and input, you must use the Blender-specific nodes this addon adds, otherwise the results may not be displayed properly! Using the Blender-specific nodes won't affect generation, results will still be saved as ComfyUI standard data.
- Generate
By clicking Excute Node Tree in n-panel, or the little red button on the right in header in node editor, current node tree will add to queue list.
You can cancel current running task by clicking Cancel, clear all task list by clicking ClearTask.
Loop execution is in advanced executing option at the side of Excute Node Tree button.
Special Nodes for Blender
Input Image
- Input image from directory
- Input image list from directory
- Input image from render(Supports current and selected frames)
- Input image from viewport(Supports real-time refresh)
Mask
- Create a mask from Grease Pencil
- Create a mask by projecting an object on the camera
- Create a mask by projecting a collection on the camera
Mat Image
- Input texture from object
- Input textures from collection objects
Save Image
- Normally saves to a folder
- Can save to an image in Blender to replace it
Multiline Textbox
To improve writing long prompts, we made a button that can show all prompts in a separate textbox since Blender doesn't support multiline textboxes in nodes. When you click the button on the side of the textbox, a window will open to write prompts in. The first time you do this, you might need to wait. Keep your cursor over the window while typing.
Shortcut Keys
Link
Select a node, then hold D and drag the cursor to another node's center, you can link all available widgets between them
Search Widgets
By pressing R when the cursor is near a widget, a pie menu will display all nodes that have this widget
Mask Link
Hold F and drag the cursor to a mask node, it will automatically create a camera to generate mask from the scene
Notes
- Not every node can work perfectly in Blender, for example nodes regarding videos
- You can enable the console under
Window>Toggle System Consoleat the top left - Model preview images need to have the same name as the model, including the extension, for example -
model.ckpt.jpg - Do not install as extensions
Tested Nodes
Here are some interesting nodes we've tested in Blender
√ = works as in ComfyUI web
? = not all functions work
× = only a few or no functions work
