NavMeshBoundsVolume isn't showing green / walkable areas

Hi everybody!

I’m experiencing some difficulty working with NavMeshBoundsVolume. The goal is that I have an object that can navigate from point A to B as a wayfinder for the player. It’s my first time trying to implement AI movement in Unreal. Following instructions, I started out by putting in the NavMeshBoundsVolume, and when “P” is pressed, there are only these black lines but no green surface area which would signal a walkable surface.

I have tried implementing everything else for the AI movement (and it seems like it would work), but the NavMeshBoundsVolume is not functioning, hence the movement does not happen.

Here are some things I have already checked or tried:

  • The landscape has Collision (BlockAll)
  • NavMeshBoundsVolume covers the whole area (It is selected in the attached image)
  • I have “built” all Levels
  • Switched Runtime Generation in Project Setting from “Static” to “Dynamic”

One thing I noticed: When I move the landscape, a green surface area appears for 1 second and then disappears again.

I’d be sooo grateful for any ideas on how I could fix this. Unfortunately I have not found a single solution online.

Thank you so much <3

Hi there, did you check that the Landscape has navigation thing on (Sorry I can´t check the right name of it, im on Work now xD)? There should be a boolean (a box which you can check or uncheck) for Navigation.
The other thing what I remember is, that eventually the BlockAll blocks also the nav mesh. Dynamic Generation works only when the game is started. Before it is disabled. So this could also be a missunderstanding?!
