V1 - General Upscaler + reskin
The Upscale Generalist works for pretty much all image types. It uses a converted FP8 Version of the JasperAi Upscale Controlnet (for faster infernece) as conditioning combined with SDUltimate upscale. There are two different versions of the workflow. One is a general upscaler that works with every image style while V2 is optimized for upscaling faces, focusing on a more realistic skin texture. Jump with key 1,2,3 between each upscaling pass and control the strength via the silder. With key 1 u can bypass the groups. Pass 1 and Two are good for general upscaling, Pass 3 is made for retexturing skin - it uses @denrakeiw new skin LoRa for this process. All settings that I prefixed in this wf work pretty good for me but pls feel free to adjust it to your needs.

Big Shoutout to @denrakeiw for the nice jam session

V2 - Regional Detailer/Upscale

With V2 of the Upscaling Generalist u are able to upcale more detail in precise areas. Use segfromer or sam2 for auto masking and define the region that should get a more attention. The Noiseblend passes blend a noise layer on top of the given mask, like a region specific nosie injection to get more regional depth and detail.

Jump with key 1,2,3 between each upscaling pass and control the strength via the silder. With key 1 u can bypass the groups. Pass 1 and Two are good for general upscaling, Pass 3 is made for retexturing skin - it uses denrakeiw new skin LoRa for this process.

For less hallucinations use low denoise values like 0.13-0.08 and the multiplysigma between 0.5-0.2. To achieve the best possible results you should work iterativ, always go a bit lower per pass. Here a quick example pass1denoise=0.13 pass2denoise=0.099

All settings that I prefixed in this wf work pretty good for me but pls feel free to adjust it to your needs.

Have fun and enjoy.
