.nav for a map

[wrock]

Hi, how can i make a *.nav file for a map?

[LordBhorak]

The fastest way is to:
Go into the map, open console, type:
sv_cheats 1
nav_generate

And there you have it. At least you have the .nav file. I'm not too good in creating navs, so others can tell you more.

This page (http://developer.valvesoftware.com/wiki/Navigation_Meshes) helped me out for editing the nav mesh. Using the nav_generate command like LordBhorak said will get your bots running around pretty good. I had to go in and edit some areas, like windows you want them to be able to jump through and stuff. Hope that helps.
