Godot 4: Raymarching, part 5 (tutorial)

Hi everybody. Let's continue our series on modeling 3D scenes using shaders and raymarching technology. In the previous fourth part, we managed to render the scene from any position and at any angle, which is very useful in itself, but we were still rendering each object in the same monotonous color. This time, we'll fix that detail and rewrite our code so that we can assign a different material to each object.
