Curious about lightning/electricity/Fire

Hey all. Im curious, what are some ways that you guys make Fire, Lightning bolts and electricity VFX without relying on flipbooks? Procedural and non-procedural is welcome. I’m looking for examples, tutorials and other things for peeps (me lol) to use as references. I would prefer examples with Niagara, but Unity is fine too!

i’m also someone who hasnt used Houdini (so expensive! and i can’t export the stuff i make with the free apprentice version i dont think :smiling_face_with_tear: i also can’t afford embergen)
