Evil Wavy Cloud Of Smoke - Real Time VFX

These is an evil cloud of smoke I made in Unreal Engine with Niagara.
I also presented main steps of my workflow. One of these four variations will be used in my biggest Unreal project, which I'm working on.
Final video files exported in 4K with a file size less than 250 MB.
Many thank's to Ashif Ali for his awesome tutorial, who provided me with a solid base to create my own versions of clouds of smoke.
