What comfyui settings and nodes does the Upscaler use?

[mdkberry]

I need to API batch produce some upscaling in Comfyui, and can't seem to imitate the Krita upscaler (I use Comfyui in backend for ACLY plugin)

I use an upscale lora in Krita and add Flux in at 20% setting, but leave everything else on default. But trying to make the equivalent in Comfyui I get weird artifects and doesnt do the same quality job.

Anyone know the secret sauce for the Upscale settings on Kirta ACLY plugin so I can create a batch workflow for API to use with it?

or even batch flow into Krita if that is possible. I just need it to work and run overnight.

There are no secret sauces in Krita AI, you can always study the workflow it generates on the fly (Configure / Generate / Dump workflow). To use the workflow in ComfyUI, all you have to do - usually - is to replace the input and output nodes with the standard Load Image and Save Image, maybe one or two more.

The only possible complication I see here is that in the Upscale / Refine mode Krita AI generates workflows that weave a mini pipleine for each tile that it breaks the image to; that makes them very busy constructs indeed. Not something you could produce by hand for sure.
