I just recently started mapping again and I'm already running into problems:
I'm trying to use the gl_wireframe command in a multiplayer-only modification, but I keep on getting an error stating I cannot use it in multiplayer. I start a server, set sv_cheats to 1, set sv_lan to 1 or deathmatch to 1, restart and try typing in gl_wireframe 1 and it gives me the same error.
I remember getting it to work over a year ago, but I forgot how.
Also, I'm trying to get this to work so I can see if any brushes in my map are clipping each other.
