In Godot, the standard get_tree().change_scene and get_tree().change_scene_to methods create a rather uninspiring scene transition. If possible, I'd like a plugin or at least a video explaining how to handle scene transitions in a better fashion, where I can do custom shaders or custom animations in such a way that my level transitions look good without being too hard on the device the game is on. The reason I need that is most of my games are on mobile, and lower-end Android devices are still quite bad with hardcore stuff (even alpha/transparency changing can cause serious issues on them).
