Godot 4: Raymarching, part 1 (tutorial)

Hi everybody! Let's try something a little different today - an introduction to creating complete 3D scenes using shaders. Yes, I know - this technology, called ray marching, has been described many times in other tutorials, and it's hard to come up with something entirely new. Still, I think it wouldn't hurt to add such a video to our collection because I plan to expand on this topic in a new series, and it would be good to have a reference for the absolute basics.
