Source Engine.
I tried:
-game $gamedir $path\$file -lights de_metro -game $gamedir $path\$file -lights de_metro.rad -game $gamedir $path\$file -lights D:\mapping\maps\de_metro\other\de_metro -game $gamedir $path\$file -lights D:\mapping\maps\de_metro\other\de_metro.rad
I made a file in both D:\mapping\maps\de_metro\other\de_metro.rad and C:\My Programs\Steam\steamapps\common\Counter-Strike Global Offensive\csgo (there is where lights.rad). I prefer to have it on another dir then the cs dir for backup purposes. But for now, getting it to work would already be great.
Is there someone that can get it to work? And if so any idea what I do wrong?
