main mistake is to upscale, at once - by x4. im using USx4 in 3 different manners (hires fix, lownoised img2img and ext-ra). and no one use scaling rate by 4x. ONLY BY 2x. yes, this is SLOWLY, especially on last level|stage (to 8k), but, possible to achieve high and realistic detailing, even in "handy drawn" styles (wet-, oil-painting, etc.). need to use upscaling with prompting support: that support additionally underline desired texturising for upscaled surfaces.
btw, when you do txt2img with hires fix, you have to first remake the photo right?(from the same seed and settings) So if you want to upscale some photo you would have to go into img2img and use resize, but then u use models (like euler) and not upscaler, like ultrasharp? Is there any way to use hires fix in img2img, or we are stuck with models? Or is it something as an option in comfyui? didn't touch that yet c:
found out there is upscaler for img2img in settings. But just spent hours because today for no reason the whole gui shows error on each setting, some json parse error in script, can't find answer for it ;/ but at least the sd is working... i think
Your tutorials on SD have been a _huge_ help. Very straight forward, not extraneous information, just what's important and why. Thank you.
Thx for the feedback, it's appreciated.
