Insurgency uses Nextbot Navigation Meshes for the AI, which is the same system used in Left 4 Dead and Counter Strike Source. The concept is to draw 2D flat meshes on top of the world geometry to indicate the walkable space to the AI.
Although there are many automated systems to facilitate the process, it is always necessary to manually polish the nav mesh after generating.
Here are a few tutorials about Navigation Meshes:
Pro Tip : The game will automatically analyze the nav right after generating it, which takes a substantial amount of time. Since you will have to re-analyze the nav after any changes you do, you may want to speed up the process by entering the following cvar "nav_max_distance 1" Once you are done editing your nav, simply reset this cvar to the default value, and analyze the nav.
