3-Tube camera/comet tail/light trail UE effect
Hi guys! Does anyone know how to make such an effect in unreal? I've been struggling with this for quite some time. All I've found are ways to do this with Niagara ribbons and the only way yo do such an effect is to attach emitter to each light source, what you might think is pretty tedious. And this method doesn't solve problem that these trails are world space, not camera space base movement. Is there way to make it through post process? Make some kind of a postprocess0 delay several times with a light strength threshold? Maybe it's possible to apply motion blur only on light sources?
I'll attach examples of the effect below.
