Does fog even work in MP?

So, my friend an i are playing G-Mod via LAN and we can’t get fog to work, witch is a shame as we really need it for our stuff. I don’t know if this is late or if it is just us but if anyone know anything about his please let me know .

fog should work in mp last time i checked

Doesn’t for us, weird, should Sv_cheats be 1 in this case?
