The minimum region area
As all possible walkable areas will be added to the navigation mesh, we have criteria that
specifies the minimum area size, which will prune out any small isolated islands of naviga-
tion. Lowering this value based on your sandbox layout will decrease the amount of time it
takes to pathfind on the navmesh. By default, a minimum region of 50 meters squared (50
meters times 50 meters) works well for the obstacle course geometry.
A navigation mesh with a minimum region size of 50.0 square meters
With a default minimum region area of 50 meters squared, the navigation mesh will not be
generated on the small concrete outcroppings on the top of the map, as shown in the pre-
ceding screenshot. If we lower the minimum region area to 15 meters squared, these out-
croppings will no longer be discarded.
