Left 4 Dead uses the navigation mesh to spawn infected. The director uses the Navigation Mesh when deciding where to spawn infected as well as other factors such as light intensity and line of site. By altering the mesh, it is possible to change the type of infected spawning (such as hospital patients and so on) and the density of their spawn.

NOTE: This article was written with experimental information and may not be 100% accurate. This article also assumes that you have read and understood the [[Navigation Meshes]] article.
 
==Marking==
Marking is as important in Left 4 Dead than it is in Counterstrike. While in counterstrike it affects how bots behave, in Left 4 Dead it both controls how they behave and how they spawn. By marking an area with certain attributes certain spawning behaviours can be created. Marking is the same as in Counterstrike, except with extra attributes, such as:
 
{{:Navigation Mesh Attributes (L4D)}}
 
As you can see, some of these are obvious, and will require experimentation to create the right amount of spawn density or to discover their function.
 
==Place Names==
The type of infected spawned depends on place naming. Simple as that. Simply by looking at the place names that appear on the console input of nav_use_place should give you the right idea of which one you want to use for that particular area. For extra detail, go into scripts/population and read it yourselves. Or, if you're too lazy for that, here it is (numbers indicate percentage of group that will spawn that model out of 100 percent, place names are in '''bold'''):
