Spawned Actor doesn't affect NavMesh

Hi there,
I have a little building system setup, where i can place actors at runtime on my mouse position (Walls and Stuff). I also can move Characters by selecting them and right-click on a location. I does the movement with “Simple Move to Location”.
My Problem is that the Characters moves through the spawned Actors. If i place the Actors in the Editor the Character moves around the Actor as it should.

I also execute the Console command “RebuildNavigation” after i spawn an Actor.

  • I checked rebuild at Runtime for the NavMesh
  • The Collision for the Actors are “BlockAll”
  • The Collision for the Characters are “BlockAll”
  • UE 4.4.3

A other little problem i have is that i can’t display the navmesh while playing. The Console command “show NAVIGATION” has no effect :frowning:

i fixed it. The Navmesh doesn’t show because i use Dedicated Server and the Navmesh only shows on the Server.
I fixed the other Problem by spawning the Actor on the Server and not on the Client.
This Question can marked as resolved. :slight_smile:

How to do actors collision right so they will not bump to each other but find their path right? I need to add them to nav mesh somehow?
