I am currently working on a navigation implementation for generated cities. Right now the Navmesh is generated by one big Nav Mesh Bounds Volume. I know this might not be the best solution, but this question is not aimed to solve that.

I am looking for a solution to make the Navmesh only generate on certain actors. The reason behind this is that I would like to only have a navigation on streets and not on any surface. The streets consists of several actors.  
And since the city is generated and quite huge, I cannot do that manually.
