I am not very good at VFX and I am not trying to recreate the first effect shown in the video, but the one thing I saw in the video which struck my interest was the ring of lines going up which went around the center Black Hole.
If anyone knows how to create a smooth ring effect similar to the video I would greatly appreciate any tips or pointers that could create that smooth ring.
I think you just need to have one big part (probably a union version of your ring of parts) and then mess around with a bunch of the particle settings with attachments of course, and try to make it to your liking. (You have to make sure you also have a particle image ready)
