Expanding Particle Rings
🕑 Added 2018-03-25 22:24:48 +0000 UTC I'm confident everyone could figure this out eventually, but it took me a few hours to fiddle the math into the right form, so here, save ya some time.This is exactly what it says on the tin. You want an expanding ring of particles, right? Thousands of uses. Anime stuff uses this constantly. The thing is, if you just expand the ring, the particle density gets lower as the ring gets bigger, and the relationship of radius to emission rate to keep the density consistent is non-linear.
So, here ya go. Set your ring emitter up like this, and attach the below component, and blammo, nice expanding rings of particles with consistent emission.
