>>57359400There's an anon who's been posting AI versions of Koikatsu images occasionally but that's separate. There's 2 things I assume you're thinking of here. The first is going to addon settings by pressing F1 and going to the settings for the screenshot manager (just search it in the bar to make it easier) Then you'll want to make sure your upsampling is at the maximum
unless you have a weak GPU that can't handle thisThe alternative is to install the post processing addon which gives you a shitload of effects to play around with, but they're very fucking tedious to use. You can get good results, but yeah.
The third alternative is in case you're REALLY new, then you want to System -> Settings and both the Character Lighting and Scene Effects tabs to mess with stuff there. Personally I only do that + the upsampling to get decent results because I find the post processing mod too annoying to use, but if you have that level of patience then the mod is much more thorough in its capabilities.
