SplineLoftActor user guide?

Is there a splineLoftActor tutorial anywhere?

I’m trying to add a line for the player to follow, but every time I try to add it, I can’t alter or amend it’s route or add additional nodes, it also doesn’t seem to add the actor in the end.

Guys need help urgently!

Come on guys someone must know how to insert and use a spline loft actor in ue4.
