ok, I had modified the halflife.fgd, as it said to in the tut, but then I came to a section of my map where I needed armoury, so I switched to halflife-cs.fgd. I then noticed that the ZHLT light flags were missing obviously because I hadent modified halflife-cs.fgd. The tut doesnt explain how to mod it, and its the one I have to use. Help anyone? How do I mod it to use the light flags.....mostly on doors...
