How to spawn an actor on walls aways facing the same direction ?

Acctually this whole thing helped by a lot ty.

I awready see the potential and it awso fixes another problem that i had with placing traps on a lets say a 45° ramp (Befor it worked only on perfectly flat surface so 90° for example). I can do it now with what i have from your nodes added to my system. I will really have to dig deeper and refine it till this fully works. Unfortunatly I don’t have more time right now but i will come back later in few hours and start working on this.
