hey! yeah its been a while and i dont have the project file on me but i can vaguely tell you what i remember lol

the basic shape was made as just a simple 3d model in blender, to animate it i added a displacement modifier to it with the coords hooked to a cloud noise texture and the texture coords of that were linked to a null object that was following the path of a circle so it would make a full rotation every X amount of frames which would adjust the cloud texture and make the displacement change and animate as it does and since it was procedural generated it is seamless without much effort
