Face swapping in Stable Diffusion using the ReActor extension is an innovative way to create engaging and unique images. Whether you want to swap faces for fun, create art, or work on a professional project, this guide will walk you through the entire process. We’ll cover everything from prerequisites to detailed steps, ensuring you have a comprehensive understanding. Let’s dive in!

Prerequisites

Before we begin, there are a few essentials you’ll need to have in place:

• Stable Diffusion WebUI (Automatic1111 is a popular option)
• ReActor Extension installed within the WebUI

Installing the ReActor Extension

1. Accessing the Extension Installation

First things first, if you haven’t already installed the ReActor extension, follow these steps:

1. Navigate to Extensions in Automatic1111:
   • Open your Stable Diffusion WebUI.
   • Go to the Extensions tab.
   • Select “Install from URL.”
2. Find the Installation URL:
   • A quick web search for “ReActor Stable Diffusion extension” should provide you with the installation URL.
   • Copy the URL.
3. Install the Extension:
   • Paste the copied URL into the “Install from URL” section.
   • Click on “Install.”
   • Wait for the extension to download and install.

Once the installation is complete, restart the WebUI to activate the extension.

Preparing Your Images

2. Choosing the Right Images

For a successful face swap, you need two images:

• Source Face Image: The image containing the face you want to use.
• Target Image: The image where you want the face to be swapped.

Ensure both images are of high quality and have clear, visible faces to ensure the best results.

3. Uploading the Source Face

1. Go to the img2img Tab:
   • Navigate to the img2img tab in the Automatic1111 WebUI.
2. Enable ReActor:
   • In the img2img tab, find the ReActor extension section.
   • Enable it by checking the checkbox.
3. Upload the Source Face:
   • Click on the upload button in the ReActor section.
   • Select the image containing the face you want to swap in.

Configuring ReActor Settings

4. Fine-Tuning the Settings

To get the best results, you’ll need to adjust a few settings within ReActor:

1. Enable Face Mask Correction:
   • Check the box for “Face Mask Correction.” This helps in maintaining the natural look of the face after swapping.
2. Restore Face Settings:
   • Choose “CodeFormer” under the “Restore Face” settings. This option ensures that facial details are preserved during the swap.
3. Swap In Source Image:
   • Ensure that “Swap In Source Image” is selected. This setting tells ReActor to use the uploaded source face for the swap.

Uploading the Target Image

5. Starting the Face Swap Process

Now, it’s time to upload the target image where you want the face swap to occur:

1. Scroll Up in the img2img Tab:
   • Locate the section to upload your target image.
   • Click on the upload button.
2. Select the Target Image:
   • Choose the image where you want the face to be swapped.

Refining the Prompt (Optional)

6. Adding Text Prompts

To guide the face swap process, you can add text prompts in the img2img tab. For example, you can specify:

• “Person with [source face celebrity’s name] face.”

This helps the AI understand the desired outcome more clearly.

Generating the Swapped Image

7. Creating the Final Image

1. Click on Generate:
   • Once all settings are configured, click on the “Generate” button.
   • Stable Diffusion will process the images and create the swapped face image.

Additional Tips and Tricks

8. Multiple Face Swaps

ReActor can handle multiple face swaps in a single target image. To do this:

• Provide a comma-separated list of face numbers in the “Target Image” section.
• This corresponds to the faces you want to swap within the target image.

9. Upscaling for Better Quality

After completing the face swap, consider using the “Upscale” feature in ReActor:

1. Select the Upscale Option:
   • This option can be found in the ReActor settings.
   • Choose the desired upscaling level.
2. Generate the Upscaled Image:
   • Click on “Generate” to enhance the image quality.
