I recently bought a copy of Garry’s Mod, it’s a very excellent game. I had problems when I joined to other public servers, the props came out in pink and black square tiles. I only own a copy of Portal, Half-Life 2: Deathmatch and Half-Life 2: Lost Coast, the game says it only requires one game which has Source Engine. If not, Do I have to purchase all the games in the ‘Extension’ list in the main menu?
If there’s another way I can download the texture, that would be most helpful (:
