This is the workflow I usually use as a base for any type of upscale. In addition to this workflow, you'll need specific model to upscale. Remember to download them.

VERSION 2.Z

-Add Hires Fix for better quality upscaling

-Improved graphics

-Improved functionality and prompt division

-Added separate VAE and enabled it for V-PRED models

-Add bookmark

-Node colors coordinated with my other workflows, so as not to cause confusion

-Added explanatory notes.

General rules:

-The workflow is intended as a basis for upscaling, not for image creation.

-You must (always) select the steps and the cfg based on the model you're using. The positive and negative prompts. Denoise is really important. Other things don't change.

-There are custom nodes; you can add them to have my workflow once opened.

I haven't been in this wonderful world for long, so I still have a lot to learn. I might update it over time if I find something isn't working well.
