Thank you vary much…
This is a lot of help 
Now i have a place to start…
Already thinking some stuff up. like trying to implementing the SwarmInterface in the runtime library so i can procedurally generate a map and build the lighting in game via a blueprint function.
Working on a 3D Level generator that can make it possible to generate maps using standardized room types, like rooms with stairs, corners, T-junctions and so on.
Currently my main problem is that the lighting needs to be built/baked after the map is generated and as far as i know that’s only possible in the editor.
With this i can also start implementing some procedural stuff that gets overly complicated in the blueprint graphs in a blueprint function library.
Anyways thanks a lot.
