Found this export rummaging through my files. A side project I was working on. I'd found myself not really liking a lot of the solar vfx I'd been seeing in tutorials so I played around trying to make one myself. I'd be interested to know if anyone else has done something similar and would like to see it!
Hope this link works
I haven't touched this in a while but remember being stuck on how to create the bursts and solar flares, which is probably why I never went back to it.
