Stable Diffusion Outpainting Tutorial - Forge UI #stablediffusion
TLDRThis tutorial covers outpainting using Stable Diffusion Forge UI, a technique for expanding image borders by adding new elements. It guides viewers through installing the Mosaic outpaint extension, generating an image using text prompts, and using the Mosaic tab to expand image areas. The video explains how to adjust settings like direction, method, and mask overlap for outpainting, and demonstrates the inpainting process to seamlessly blend new areas with the original image.
Takeaways
- 🖼️ Outpainting is a technique used to expand the borders of an image by adding new elements to its edges.

- 🔗 Visit the GitHub page for the extension to learn about its usage, parameters, and examples.
- 💾 After installing the extension, apply and restart the UI to complete the setup.
- 🎨 Test outpainting by generating an image using the 'Text to Image' section with a specific style and aspect ratio.
- 📂 The Mosaic tab provides options to input an image, choose the direction for expansion, and select the method (stretch or mirror).
- 🔄 The 'Horizontal' and 'Vertical' expand options control the size of the expanded area.
- 🖱️ The 'Mask Overlap' setting determines how much the mosaic overlaps with the original image.
- 🔄 The 'Send to Inpaint' button transfers the mosaic to the inpainting process.
- 🖌️ Use 'Mask Mode' and adjust settings like 'Denoising Strength' for better inpainting results.
- 🖼️ After outpainting, use the 'Send to Extras' tab with an upscaler to increase the image size.
Q & A
What is outpainting in the context of digital art and image editing?
-Outpainting is a technique in digital art and image editing that involves expanding the borders of an image by adding new elements to its edges, essentially revealing more of the scene beyond its original visibility.
How can you access the extension tab in Forge?
-You can access the extension tab in Forge by navigating to it after opening the application.
What is the name of the extension needed for outpainting in the tutorial?
-The extension needed for outpainting in the tutorial is named 'Mosaic outpaint tab'.
Where can you find more information about the Mosaic extension?
-You can find more information about the Mosaic extension, including how to use it, its parameters, and examples, on its GitHub page which you can access by clicking on the extension's name.
How do you install an extension in Forge?
-To install an extension in Forge, search for it, click install, and wait for the installation process to complete. After that, go to the installed tab and click on apply and restart the UI to finalize the installation.
What is the purpose of the Mosaic tab in Forge?
-The Mosaic tab in Forge allows users to input their images and choose the side of the image they want to expand by selecting one or more directions.
How can you input an image into the Mosaic tab?
-You can input an image into the Mosaic tab by dragging and dropping it, uploading it, or using the copy-paste shortcut (control+v) after right-clicking on the image you want to use.
What are the two methods available for expanding an image in the Mosaic tab?
-The two methods available for expanding an image in the Mosaic tab are 'stretch', which stretches the selected part of the image, and 'mirror', which mirrors the image.
What does the mask overlap option control in the Mosaic tab?
-The mask overlap option controls how much the generated mosaic overlaps with the actual image, affecting how the inpainting process modifies the image.
How do you send the expanded image to the inpainting process?
-You can send the expanded image to the inpainting process by pressing the 'send to inpaint' button in the Mosaic tab.
What settings are recommended for the denoising strength in the inpainting process?
-For better results, the denoising strength should be set between 0.9 and 1.
Can you upscale the final image using Forge?
-Yes, you can upscale the final image using the 'send to extras tab' button and then using the DX2 upscaler with a resize value of two.
How does the outpainting process differ when using Photoshop compared to Forge?
-In Photoshop, outpainting is done using the crop tool with the generative expand option, where you can adjust the crop area and choose a ratio. The process in Forge involves using the Mosaic tab to expand the image and then inpainting to blend the new area.
Outlines
🎨 'Out Painting' with Stable Diffusion Forge UI
The paragraph introduces the concept of 'out painting' in digital art, which is expanding the borders of an image by adding new elements. It describes the process of installing the Mosaic out paint extension in Stable Diffusion Forge UI, including loading extensions, searching for the Mosaic out paint tab, and installing it from GitHub. The tutorial then demonstrates how to use the extension by generating an image of a bunny in a fantasy forest using the text-to-image section. It explains how to input an image into the Mosaic tab, choose the direction for expansion, and select the method (stretch or mirror) and the amount of expansion. The paragraph also covers the mask overlap option and provides a step-by-step guide on how to send the expanded image to the inpaint process, adjust settings, and generate the final image. It concludes with a note on the importance of the denoising strength and a prompt for image generation.
🖌️ Enhancing Image Details with Photoshop and Forge
This paragraph discusses how to refine the 'out painting' process using both Photoshop and Forge. It starts with a quick fix in Photoshop using the 'remove' tool and then delves into using Forge for more detailed inpaint adjustments. The tutorial guides through dragging the image to the inpaint tab, masking the area to be fixed, and using similar settings with a focus on the 'inpaint area' and 'denoising strength'. It also mentions adjusting the prompt to describe the desired outcome. The paragraph further explores resizing options and the use of 'image to image' for better blending. It provides a practical example of expanding the right part of an image, adjusting the prompt, and using different settings for 'denoising strength'. The tutorial concludes with upscaling the final image using the 'send to extras' tab and the 'do X2 upscaler'. Additionally, it touches on the alternative method of out painting using Photoshop's crop tool with the 'generative expand' option and adjusting the composition and ratio for the best results.
