    I recently saw a post from 2017 with this effect:


    I can't find anything else on the internet on how to do this, but it is exactly what I want. And I have tried so many ways of doing it. If anyone can point me in the right direction of how to go about this, that would be awesome.

    Thanks!

    It’s our Ringbuffer Mode. @karl_jones did we ever share that demo publicly?

    EDIT: it seems it wasn’t our ringbuffer mode! (See posts below for details!)

    That gif won't be from our ring buffer if it's from 2017 however that effect can be done using the ring buffer. We did not share the project but I'll see if I can put together an example shortly.

    well I can't tell if you need the particle details since you found the post and karl included a zip
    or something else? but at the time that test was not using ring-buffer (dont think it existed in 2017)
    https://forum.unity.com/threads/spa...-rotation-of-the-emitter.469659/#post-3062164

    1. simulation space = World
    2. renderer>render_alignment = 'velocity'
    3. renderer>render_mode > Mesh = Quad
    4. start speed = .001 (< important to establish a minimal vector)
    5. start rotation 90x,0y,-90z

    as for having them spawn based on distance vs rate, that's no problem, or according to a script that is certainly doable. And a single image, and one 1 emitter set to FLIP. or you could probably just use the same emitter but you'll have to pass a FLIP toggle
