I have explained on Blender Stack Exchange how to create pre-rendered sprites and use them in Godot. This technique was popular in the early 2000s games in RTS and real-time tactic games.

The pre-rendered sprites allow to create good looking top down orthographic games that use very low resources, it is possible possible to display a lot of characters at once on the screen even on a mobile device.
