ReActor Node is an extension for ComfyUI that allows a very easy and accurate face-replacement (face swap) in images

What's new in the latest update

0.4.0 _^BETA2

• Ability to build and save face models directly from an image:

• Both the inputs are optional now, just connect one of them according to your workflow; if both is connected - image has a priority.

0.4.0 _^BETA1

• Input "input_image" goes first now, it gives a correct bypass and also it is right to have the main input first;
• You can now save face models as "safetensors" files (ComfyUI\models\reactor\faces) and load them into ReActor implementing different scenarios and keeping super lightweight face models of the faces you use:

• Different fixes making this extension better.

Thanks to everyone who finds bugs, suggests new features and supports this project!

   • Install Visual Studio 2022 (Community version - you need this step to build Insightface)
   • OR only VS C++ Build Tools and select "Desktop Development with C++" under "Workloads -> Desktop & Mobile"
   • OR if you don't want to install VS or VS C++ BT - follow this steps (sec. I)

   • GFPGAN: https://github.com/TencentARC/GFPGAN/releases/download/v1.3.4/GFPGANv1.4.pth
6. Run ComfyUI and find there ReActor Node inside the menu ReActor or by using a search

Usage

You can find ReActor Nodes inside the menu ReActor or by using a search (just type "ReActor" in the search field)

List of Nodes:

• ReActorFaceSwap (Main Node)
• ReActorLoadFaceModel (Load Face Model)
• ReActorSaveFaceModel (Save Face Model)

Connect all required slots and run the query.

Main Node Inputs

• input_image - is an image to be processed (target image, analog of "target image" in the SD WebUI extension);
  • Supported Nodes: "Load Image", "Load Video" or any other nodes providng images as an output;
• source_image - is an image with a face or faces to swap in the input_image (source image, analog of "source image" in the SD WebUI extension);
  • Supported Nodes: "Load Image";
• face_model - is the input for the "Load Face Model" Node or another ReActor node to provide a face model file (face embedding) you created earlier via the "Save Face Model" Node;
  • Supported Nodes: "Load Face Model";

Main Node Outputs

• IMAGE - is an output with the resulted image;
  • Supported Nodes: any nodes which have images as an input;
• FACE_MODEL - is an output providng a source face's model being built during the swapping process;
  • Supported Nodes: "Save Face Model", "ReActor";

Face Restoration

Since version 0.3.0 ReActor Node has a buil-in face restoration.
Just download the models you want (see Installation instruction) and select one of them to restore the resulting face(s) during the faceswap. It will enhance face details and make your result more accurate.

Face Indexes

ReActor detects faces in images in the following order:
left->right, top->bottom

And if you need to specify faces, you can set indexes for source and input images.

Index of the first detected face is 0.

You can set indexes in the order you need.
E.g.: 0,1,2 (for Source); 1,0,2 (for Input).
This means: the second Input face (index = 1) will be swapped by the first Source face (index = 0) and so on.

Genders

You can specify the gender to detect in images.
ReActor will swap a face only if it meets the given condition.

Face Models

Since version 0.4.0 you can save face models as "safetensors" files (stored in ComfyUI\models\reactor\faces) and load them into ReActor implementing different scenarios and keeping super lightweight face models of the faces you use.

To make new models appear in the list of the "Load Face Model" Node - just refresh the page of your ComfyUI web application.
(I recommend you to use ComfyUI Manager - otherwise you workflow can be lost after you refresh the page if you didn't save it before that).

Troubleshooting

I. (For Windows users) If you still cannot build Insightface for some reasons or just don't want to install Visual Studio or VS C++ Build Tools - do the following:

1. (ComfyUI Portable) From the root folder check the version of Python:
   run CMD and type python_embeded\python.exe -V
2. Download prebuilt Insightface package for Python 3.10 or for Python 3.11 (if in the previous step you see 3.11) and put into the stable-diffusion-webui (A1111 or SD.Next) root folder (where you have "webui-user.bat" file) or into ComfyUI root folder if you use ComfyUI Portable
3. From the root folder run:
   • (SD WebUI) CMD and .\venv\Scripts\activate
   • (ComfyUI Portable) run CMD
4. Then update your PIP:
   • (SD WebUI) python -m pip install -U pip
   • (ComfyUI Portable) python_embeded\python.exe -m pip install -U pip
5. Then install Insightface:
   • (SD WebUI) pip install insightface-0.7.3-cp310-cp310-win_amd64.whl (for 3.10) or pip install insightface-0.7.3-cp311-cp311-win_amd64.whl (for 3.11)
   • (ComfyUI Portable) python_embeded\python.exe -m pip install insightface-0.7.3-cp310-cp310-win_amd64.whl (for 3.10) or python_embeded\python.exe -m pip install insightface-0.7.3-cp311-cp311-win_amd64.whl (for 3.11)
6. Enjoy!

II. "AttributeError: 'NoneType' object has no attribute 'get'"

This error may occur if there's smth wrong with the model file inswapper_128.onnx

Try to download it manually from here and put it to the ComfyUI\models\insightface replacing existing one

III. "reactor.execute() got an unexpected keyword argument 'reference_image'"

This means that input points have been changed with the latest update
Remove the current ReActor Node from your workflow and add it again

IV. ControlNet Aux Node IMPORT failed error when using with ReActor Node

1. Close ComfyUI if it runs
2. Go to the ComfyUI root folder, open CMD there and run:
   • python_embeded\python.exe -m pip uninstall -y opencv-python opencv-contrib-python opencv-python-headless
   • python_embeded\python.exe -m pip install opencv-python==4.7.0.72
3. That's it!

Updating

Just put .bat or .sh script from this Repo to the ComfyUI\custom_nodes directory and run it when you need to check for updates

Note!

If you encounter any errors when you use ReActor Node - don't rush to open an issue, first try to remove current ReActor node in your workflow and add it again

ReActor Node gets updates from time to time, new functions appears and old node can work with errors or not work at all
