How would I recreate Elite Dangerous' speed lines?

Hi everyone! I’m trying to make my very own space-sim game in Unreal Engine 4 and I just don’t know how to produce the speed lines (“space dust thingies”) in the Engine. I don’t really know the engine well (and have no money to spend on the marketplace), so can anyone point me in the right direction so I can un-stuck myself?

The effect I’m trying to make is best described with an image : Speed Lines

Thanks!

Post process is you best bet:

In case you wonder what material Post Process domain is, the pic at the very bottom:

This is a neat effect but not the one I’m looking for : it needs to show speed AND direction! Or there’s a way to “rotate” the effect as if it’s from another direction? Mmhh…

uhm hello did you ever find what you were looking for because I’m looking for the same kind of thing as well
