Hello. I'm new to Godot, and have question about texture atlases for merging sprites. In other engine, that I use, I generate atlases via texture packer (cocos2d-x, libGDX, PixiJS), in Unity using packing tag for it, but in Godot I have no idea how to merge sprites to one atlas. I know that earlier sprites can be grouped, but in 3 version I can't do that. How to merge sprites to one atlas (is it any tutorial exist, I google a lot but find nothing)? Can I merge bitmap fonts and UI elements to one atlas (cause UI with a lot of text-fields generate more draw-calls than game)?
