Much much better! great work btw!
Edit: Using embed tres animation texture seems make the file size quite large.cause it may be lack some compression?
The generated size is the next thing on my list, i tried before but had some problems. Will look again in godot 4.1.
Edit: Strange thing is i AM compressing the images. The generated spritesheets have much smaller size. I really can't say why adding them by code is making it so large.
