Caveat: Renpy 8.1 (currently at 61% Pre-Release) needs to be released before this occurs. I have tested this with a nightly build, but I am not going to subject players to potential issues that might come from that. :)
One issue I have seen come up is comments about images. I don't think the source images is the problem, but rather the compression used.
The problem is:
- When I test different jpegs with different level of quality, I get really weird artifacts with Bria's ponytail.
- If I increase the Webp too much, the file sizes get even worse.
- Even worse than that, it doesn't help with the color.

Here is how Bria appears in the Game with Webp at the current setting. Even if I went to 99, I have not gotten that much clarity and colors seem a bit meh.

Screenshot from 8.1 Nightly Build with avif file. Her freckles appears, there is stranges in her hair, and things look more pronounced colorwise. So, my plan is this:
- When working on new content (was in the middle when I started the bios that needed a lot of render time. ;), I will save it in webp and avif until 8.1 comes out. Then I will push the avif as a replacement.
- Now and then I will work on converting the PSD files I have of the scenes into avif (what I did with the game menu image. :)
