I tried to work out the Garrys mod configuration before I start up Hammer, here’s how I did it.
Engine: Half life ep 1 (Since I don’t have any orange box games)
Game: Garrys mod
It opens up, I load a map, but it shows nothing but white in the camera, and everything else nothing, and I can’t do anything in it.
When I open up half life 2 on hammer with garrys mod configurations, it works fine.
