If you've ever wished to see Hollywood stars in entirely new contexts or play with your own images, you're in for a treat. Today, we're diving deep into the Reactor extension for Stable Diffusion—a powerful tool that breathes new life into face swapping. Let’s explore how to install and use this robust extension, which has everyone buzzing in the community!

Face swapping is a groundbreaking technique that allows you to artificially embed one face into another image. Thanks to advancements in AI technology, this process has become incredibly popular, particularly in the Stable Diffusion community. Users are pushing creative boundaries by transforming photos in ways once thought impossible. With tools like the Reactor extension, face swapping is not only achievable but can yield stunningly realistic results.

The Reactor extension is a game-changer for face swapping enthusiasts. With an array of impressive features, it stands out as the premier choice for anyone looking to elevate their face swapping game. Here’s what makes it remarkable:

• Continuous development: The team behind Reactor is always improving.

Ready to dive in? Let’s walk through the installation process step-by-step!

1. Deactivate the ROOP Extension: If you have the ROOP extension installed, head to the extensions tab of your Stable Diffusion web UI and uncheck the box to disable it. Don’t forget to apply these changes!
2. Prepare Your Directory: Navigate to the root directory of Stable Diffusion and locate the models folder. Rename the models folder labeled roop to insightface.
3. Visit GitHub: Head over to the official GitHub repository to download the Reactor extension. Links are in the description below the tutorial video.
4. Install Visual Studio Community: If you haven’t installed this software yet, it’s essential for the Reactor extension. Make sure to follow the default settings during installation.
5. Install from URL: Copy the ReActor GitHub URL and return to your Stable Diffusion web UI. In the extensions tab, paste the URL in the install section, click install, and then apply and restart the UI.

Now that you have the ReActor extension up and running, it’s time to put your skills to the test! Here’s how to create your first face swap:

• Navigate to the Text to Image tab.
• Open the Reactor expansion panel and drag an image onto the canvas. For our example, let’s use Angelina Jolie's face.**
• Activate the extension by checking the enable box.
• Create both a positive and a negative prompt—this gives the AI context. If you want a classy vibe, enter prompt terms that emphasize elegance.
• Hit the generate button and watch the magic happen.

The results are often jaw-dropping; you’ll see Angelina Jolie’s features seamlessly merged into your chosen image.

Let’s talk about upscaling—a feature that sets the Reactor extension apart from the competition. Upscaling takes your generated images to the next level:

1. Go to the Upscale subtab within the Reactor extension.
2. You have the option to swap faces first and then upscale, which is recommended for optimal results.
3. Choose your preferred upscaling method; though I always suggest the four times Ultra Sharp upscaler, feel free to experiment.
4. Click generate and behold the high-quality, refined image that emerges!

Remember, you can upscale as many times as necessary to meet your personal standards.

Want to take things a step further? The Reactor extension allows for multiple face swaps with a few tweaks! Here’s how:

• Begin with a source image that contains multiple faces. For this demo, let’s use a photo featuring Angelina Jolie on one side and Jenna Ortega on the other.

  

• Assign face numbers from left to right; for instance, Angelina is face 0 and Jenna Ortega is face 1.

• For the target image, input the desired new positions of the faces using the same numbering.

Target Image Explanation

Here, you can enter the face numbers (assigned in the Source Image section) that you want for the output. For instance, if I'm generating an image with two women and I want the one on the right to have Angelina Jolie's face (Face Number 0) and the one on the left to have Jenna Ortega's face (Face Number 1), I need to assign these numbers correctly, like: 1,0, within the Target Image.

Now click generate and watch as the magic unfolds with multiple faces swapped seamlessly! The possibilities are endless, and it's an exhilarating process.

From high-resolution outputs to effortless face swaps and upscaling, this tool is a fantastic addition to any creator's toolkit.
