I've released a new tutorial on my website: How to Resize Images in Ren'Py. It goes over the topic of ATL fit and how you can use it to maintain aspect ratios while resizing displayables.

I also added a writeup on my recent Visual;Conference talk if you prefer a written form for that! You can find that article on my website also here: https://feniksdev.com/character-customization-101-talk/ It includes the code excerpts in written form as well.

Next week I've got another tool release lined up: Easy Blinking! It will provide a simple way to randomize blinking times and add blinking animations to layered images and other character declarations without needing to declare individual images for each set of eyes. I hope you look forward to it!
