1080p just looked horrible ngl so they're now 1440p
This ain't pixel art. Your last screenshot is 1280x720 and has a size of almost 1MB. This is madness. Learn how to use lossy webp. With compression 80 that screen is 48kb instead of 983kb. Even with placebo setting of 100, it only is 176kb.
Do a test sample. Create webp of 100 95 ... 50 and mix it in with the original. Cycle through the images in a way that you do not know which image is displayed. Try to tell the difference.
I’m assuming the last image that you’re talking about what’s on this page and yeah that’s because there’s a file size limit lol. It’s a little big because chara studio was doubling the render output for screenshots which I fixed for the next release. I’m actually redoing everything rn lol because I don’t like the way the appearence. But the chara studio resolution is 1440p and the quality does decrease drastically when it’s less. I haven’t messed with different image types because renpy only takes so many, and it automatically takes png so it was easy for me. I honestly don’t understand half of what you’re saying but I appreciate the help and I’ll look into it.
