I had actually tried with Particles2D but the result wasn't satisfying. To add the worst, on clicking the ring nodes (after using Particles2D), the rings suddenly became distorted (due to some problem in Godot, I have checked, it's not a problem from my part), though on execution, the ball appears properly. Nevertheless, @megalomaniak and @cybereality for your suggestions. Also, I don't have Blender because I have a Chrome OS laptop that doesn't have enough space, so I use Vectary to make 3D figures. But, once, when I tried to put a 3D sprite in a 2D game, it wasn't appearing. Do I have to do something to make the 3D sprite appear?
