I’m trying to spawn several nav mesh bounds volumes at runtime. My game spawns the entire environment on play which consists of a random amount of rooms (within a range), each having some enemies within.
I glossed over some previous questions on the topic that mentioned placing the nav meshes beforehand then moving them at runtime, but I don’t know how many nav meshes will be needed before the environment is spawned which is random.
Is there a way to spawn nav mesh bounds volumes in blueprints? All I found was add nav link, modifier, and invoker components nodes.
I think the word that you are looking for is dynamic nav mesh. Very useful for a procedurally generated world as well as a huge level. Do some research on this, and you will find it helpful.
Hey there @Kyparon! Navmesh bounds volumes aren’t quite set up to be generated at runtime, though I believe with level instancing it should be possible. Then here’s a resource for setting up the dynamic nav mesh itself.

Yeah, dynamic nav mesh is what you’re looking for, don’t forget to set the runtime generation to dynamic in settings. I have a game on steam that spawns the whole world procedurally/randomly at runtime too
I need to do what the OP stated also and dynamic nav meshes seem to do the opposite of what I need.
I am creating a game where the goal is to see how long a player can survive and how many rooms the player can clear. Essentially it is an infinite runner but with enemies in each room. I thus need to update the position of the NavMesh Bounds volume each time I remove the old room and add a new one OR I need to add a Nav Mesh Bounds Volume to my room blueprints.
The tutorials I find (and the video linked to included in this thread) say “Build a NavMesh Volume that is 10000 units long on the y and infinite long on the x then do all manner of trickery to avoid the AI from reaching certain spaces”. Nothing says how to create a 10000x10000 NavMesh Volume
From what I’ve read it seems this is not something Unreal can do. Instead I have to make the volume massive and then end my infinite run game if the player reaches n rooms. Do I have that right?
Do you have 1 tyoe of room or multiple?
What I would do is add the nav mesh in the room, load it in game, and instead of remove the room and add it back, just recycle the room BP.
I had multiple rooms. The plan was to have 20 in total. The issue I have is that I can’t “add the nav mesh in the room”. How do I do that?
I don’t ever delete the rooms
What I did was spawn all rooms during Begin Play then I placed 3 after one another starting from 0,0,0 and placed the character at 0,0,0 also. Each room has a trigger so I know when the player is nice and deep into that room. Once it triggers I move the first room back into the pool and then select another room at random and reposition it at the end of the remaining two. This way, even with only 3 rooms, I can have an infinite runner
The problem is that I can’t find a way to add a NavMesh to the room blueprint. Am I missing something obvious?
