Good day! I almost did to what I need, but still got a wall for myself. I need the beam (which is in a separate emitter, of course) to be attached to EACH pair of particles that are emitted from their emitters. These white particles are in different emitters - one I named First, the other is Second…

Well, I found the best option for myself, based on limitations of the Cascade. I hope that Niagara will support the creation of more specific things. Cheers! [222034-2017-11-30-19-33-11.gif]
