Thanks dude! There’ just simple Ribbon Emitters with a panning texture actually. Essentially i just made a whispy texture, scrolled it along the ribbon and let it get stretched pretty far. Then I layered 3 of them, so there’s one additive short lived ribbon nearest the missile head, there’s one translucent one that’s darker in value underneath it which forms the bulk of the trail. Then there’s one really low value and low opacity ribbon that is actually spreading out to help give off the more spectral misty read.
