Working with 'dynamic' navigation invokers

a bit out of topic but, i have a question about navigation invoker and nav mesh generation…

  1. when i set my navigation bounds so large, lets say, 100k counting thing below when generating… it takes a long time right?..
    so, let’s say i finish generating the nav mesh, and the game is finished, does the user / player still have o navmesh map generate when they start the game?.. or they can use the generated navmesh map when the game was built?

  2. when i tried to have many characters that has nav invoker… they somehow lag the game generating the nav map. ( this was when the radius was set to 3000 only… ) so a bit small…
    could the lag go down, if the radius was big enough?..
