This condition is always true: ``max tiles number * max polygons per tile <= 4194304``.
It's a limitation of `Recastnavigation <https://github.com/recastnavigation/recastnavigation>`_ library.
wait until min distance to player
------------------------------
:Type: integer
:Range: >= 0
:Default: 5
Distance in navmesh tiles around the player to keep loading screen until navigation mesh is generated.
Allows to complete cell loading only when minimal navigation mesh area is generated to correctly find path for actors
nearby the player. Increasing this value will keep loading screen longer but will slightly increase nav mesh generation
speed on systems bound by CPU. Zero means no waiting.
