I can make an array follow a curve shape, but there is a problem here as the array wotn reappear on the opposite side when it reaches the end, and I really need that, and finally i would like to have that smooth fading of the trails likein the vid. Maybe there is a different way to achive this effect?

You may want to look at my After Effects stroke.

Just click on it in my signature.

Nice… other example made with particles, in any case you may need to duplicate and time offset the object…

I dont really get what your after effects stroke does which assigning a curve modifier to an array doesnt, except the tail is tinner ?

Here’s another example. The materials texture creates the fadeout
