Nav mesh generation: infinite loop?

I’m having some nav mesh issues, wonder if anyone else has run into them.

Desert canvas, small enclosed 4v4 map. Only spawns etc are inside that space, with nav cutters around the outside to preclude any chance of nav mesh there. Blockers, geometry etc all prevent players, especially bots, getting outside. Map is not very complex.

Yet Nav Mesh takes an age, apparently infinite, to generate. Never succeeded recently, although an earlier iteration generated nav mesh. I am confused as to what it could be: I assumed some sort of ‘bleed’ of nav mesh from the playspace to the outer area, meaning the game generates nav mesh for the entire canvas, ergo a big big chunk of data.

But then I’ve cut the map up using cutters to try and minimise the space available for nav meshing. I don’t even think this is the issue, as the game generated nav mesh outside the map without this delay before… Is it possible to overload the logic with too many cutters etc?

I must have done something that broke it, I just can’t work out what.

I had this same issue…surprised you didn’t find it when researching this before posting.
:wink:

My solution turned out to be:

  • Forge everything until you’re happy. with it.
  • Save your map.
  • LEAVE FORGE (The crucial bit that makes it work)
  • Reload your map in Forge (Latest Version)
  • Immediately upon spawning within your map, before touching anything, or even moving around the map, just - right when you spawn in - BUILD NAV MESH.

It should work…
Then just build lighting, audio, etc. and SAVE again.

Let me know your results!
This was driving me crazy too, until I began using this method.
It now works every time for me.
