Test.CSM.Dev

Нужен адекватный nav файл.
To add or change the name of a location, you need to turn on the place name editor. If you haven't already done so, you'll want to first make sure nav_edit is set to "1", then type nav_toggle_place_mode. When the place name editor is enabled (assuming no areas have been named) all the nav squares should turn red.

To select which Place Name you want to assign to an area, type nav_use_place (name), for example nav_use_place Bedroom. Next, aim your cursor at an area you want to label with that Place Name and turn on "Place Painting Mode" by executing nav_toggle_place_painting. While "place painting" is active, each area you point at will be tagged with the current Place Name you selected and will turn green in color. You can change the place name you are painting with by typing nav_use_place (newname), notice that after changing the place name, all areas already painted with a different name will turn blue and areas painted with the name you just changed to will turn green. When you are finished using "Place Painting Mode", you can exit by executing nav_toggle_place_painting again.
Кратко:
Врубаем nav_edit; пишем nav_toggle_place_mode; пишем nav_toggle_place_painting; пишем nav_use_place (areaname) и пыщ-пыщ водим курсором по нужным нам зонам. Надо другое название? Просто заменяем параметр nav_use_place.
