Can't seem to add a navigation mesh at runtime

I’ve been searching for a way to do this, but cannot find the answer:

My level (well, actually the entire game) is completely generated at runtime. (No two game experiences are ever the same.) I’m trying to add a navigation mesh so I can start adding AI characters to my game. Unfortunately, everything I’ve seemed to search up here is for an older version of the engine and does not seem to apply. In fact, the only navigation item I seem to be able to spawn into my level is the Recast Nav Mesh. (Which doesn’t seem to show up anywhere to give me any clue that anything actually was created.)

What BP node do I need to use to add a navigation mesh to my level? All the other aspects of my game prototype are complete, now I’m needing to add AI to provide obstacles (enemies) to hinder the player from reaching the goals systems I’ve already implemented.

Fortunately, my game is at a point where it’s a heck of a lot of fun to play test, so I’m up for trying a bunch of things if necessary. :slight_smile: (But I really want to get this into place ASAP.) Implementing this AI is probably my weakest area, as far as the programming goes. I apologize if this has been covered before, but I have not been able to find it.


Just an update: When I playtest the level, it says my “NAVMESH NEEDS TO BE REBUILT.” Since I don’t have anything (as far as the editor is concerned,) rebuilding ANYTHING in there is pretty much useless… at least it’s a quick useless.

Just another update. I’ve been working on some other visual aspects of the game and different power-ups, so this has taken a back seat for the moment, but I’m still kinda stuck. Got rid of the “NAVMESH NEEDS TO BE REBUILT” message by checking the Force Rebuild on Load checkbox in the Navigation Mesh project settings, but I’m still not showing any navigation mesh in my level when I unposess and change my “show” parameters to include it. So obviously I’m either not doing it correctly, or there’s nothing I can do and I’ll have to create my own navigation system from scratch. That’s not a problem, but I really don’t want to have to recreate a wheel that’s already there.
