Real-ESRGAN is built-in to the addon to upscale any generated image 2-4x the original size.
You must setup the Real-ESRGAN weights separately from the Stable Diffusion weights before upscaling. The AI Upscaling panel contains instructions for downloading them.
- Open the image to upscale an Image Editor space
- Expand the AI Upscaling panel, located in the Dream sidebar tab
- Choose a target size and click Upscale
Some GPUs will require Full Precision to be enabled.
The upscaled image will be opened in the Image Editor. The image will be named Source Image Name (Upscaled).
