Godot 4: 3D Particle Trail (tutorial)

Hi everyone! This time, we’ll take a short break from shaders and look at an equally interesting technology — particle systems in Godot 4. It's not the first time I’ve showcased something like this — for example, the fire and smoke we had here quite recently. In this tutorial, we’ll create a quite useful effect: a trail behind a moving 3D object, with the trail based on the same shape as the object itself.
