The Tiled Diffusion VAE extension is an incredible tool designed for generating or upscaling large images (≥2K) while being friendly to your VRAM limitations (≤6GB). With various advanced features, this extension offers a robust solution for artists and developers eager to push the boundaries of image generation. In this article, we’ll guide you step by step on how to set this up, generate your images, and troubleshoot common issues!

Getting Started

Before we dive into the nitty-gritty of using the extension, let’s make sure you have everything you need:

• Ensure you have the latest Stable Diffusion WebUI installed.
• Download the Tiled Diffusion VAE extension from its GitHub repository.
• Install the extension following the documentation provided in the GitHub links.

Features Overview

The Tiled Diffusion VAE extension provides various features to enhance your image generation experience:

• Tiled VAE: A specialized VAE to support high-resolution image generation.
• Tiled Diffusion: txt2img: Generate ultra-large images from text prompts.
• Tiled Diffusion: img2img: Enhance details in existing images through upscaling.
• Regional Prompt Control: Control the prompts applied to specific regions in your image.
• Advanced Features: Support for ControlNet, StableSR, SDXL, and more.

Generating Large Images with Tiled Diffusion

Let’s compare the process of image generation with the operation of a factory. Imagine your generated image as a complex machine that encompasses various parts (details). You can’t build it all at once; instead, you need to assemble it step by step, piece by piece. The Tiled Diffusion VAE extension helps you build this machine by let you focus on one section (tiled section) at a time, using virtualization to manage your limited resources.

Steps to Generate Images

1. Open your Stable Diffusion Web UI.
2. Select the Tiled Diffusion VAE option from the settings.
3. Input your desired prompt (for example: “masterpiece, best quality, highres, city skyline, night.”).
4. Click Generate to see the magic happen!

Upscaling Images with Img2Img

To enhance the details of any existing low-resolution image, follow this straightforward process:

1. Select the existing image you want to enhance.
2. Set the desired upscale factor (e.g., x4).
3. Hit the Upscale button and wait for your high-resolution masterpiece.

Troubleshooting Common Issues

Even with the best tools, hiccups might occur. Here are some common issues you might face along with their troubleshooting solutions:

• VRAM Errors: If you encounter VRAM errors, you may need to lower the resolution of your output images or try reducing the complexity of your input prompts.
• Installation Issues: Make sure you have correctly followed the installation steps. Double-check your installation of the Stable Diffusion WebUI and Tiled Diffusion VAE extension.
• Images not generating: Verify that your prompts are not too complex. Sometimes simplifying the text can resolve issues with image generation.
• Tool Not Found: Ensure you have the latest version of the Tiled Diffusion library; older versions may be incompatible with current updates.
