<h1 id="simple-text-to-image-workflow-with-controlnet-tiled-upscale">Simple Text to Image workflow with ControlNet tiled upscale</h1>This is my main workflow for SDXL/Pony/Illustrious that uses ControlNet tile upscaling. Feel free to DM me if you have any questions about the workflow.<img src="https://image.civitai.com/xG1nkqKTMzGDvpLrqFT7WA/cf6dae98-aedd-4af5-8870-8e73ef13fae6/original=true/cf6dae98-aedd-4af5-8870-8e73ef13fae6.jpeg" /><h2 id="features">Features</h2><ul><li>Two types of tiled upscaling: Ultimate SD and ControlNet with a one-click switch. <img src="https://image.civitai.com/xG1nkqKTMzGDvpLrqFT7WA/89d2d840-0b33-4c80-be77-0d2453302f5e/original=true/89d2d840-0b33-4c80-be77-0d2453302f5e.jpeg" /></li><li>Save upscaled images with Civitai-compatible metadata as PNG and/or JPG.

Set it to 0 if you're using other ESRGAN such as 4x-UltraSharp and colors in the upscaled image look too saturated.<img src="https://image.civitai.com/xG1nkqKTMzGDvpLrqFT7WA/eb7f7896-b08c-4084-afaf-c7a185f8bfe4/original=true/eb7f7896-b08c-4084-afaf-c7a185f8bfe4.jpeg" /></li><li>For low VRAM try reducing tile size in the upscaler to 512.</li></ul><h2 id="getting-started">Getting Started</h2><ul><li>Requires manual installation of <a target="_blank" rel="ugc" href="https://github.com/xxmjskxx/ComfyUI_SaveImageWithMetaDataUniversal?tab=readme-ov-file#quick-start">Save Images With Metadata Universal Extension </a>from GitHub.</li><li>Download ControlNet model from HuggingFace and put it into ComfyUI &gt; models &gt; controlnet.
