🔧 Installation and Setup of the Reactor Extension

This section provides a step-by-step guide on how to install the Reactor extension. It starts with the prerequisites, which include installing Visual Studio 2022 or Visual C++ build tools with desktop development with C++ workload. The paragraph then explains the process of copying the repository link from the GitHub page, installing the extension through the Stable Diffusion web UI, and restarting the terminal and Stable Diffusion for the installation to take effect.

🖼️ Using the Reactor Extension for Text-to-Image and Image-to-Image Face Swap

The paragraph demonstrates how to use the Reactor extension for face swapping in both text-to-image and image-to-image scenarios. It begins with a text-to-image example, where a prompt is used to generate an image, and then a face is uploaded and gender detection is activated. The paragraph then shows how to use the extension for image-to-image face swapping, where a target image is used and the denoising strength is set to zero. The process is repeated with different face models and the results are displayed, showcasing the effectiveness of the Reactor extension in integrating faces into generated images.

🌟 Advanced Usage: Multiple Faces and UPS Scaling

This part of the script covers more advanced usage of the Reactor extension, including changing multiple faces in a single image and using UPS scaling for higher quality and resolution.
