Textures Not Loading

Garry's Mod uses textures from other games, you need to install the following games for the best experience: Half-Life 2 (and its episodes), Portal, Counter-Strike: Source, and Team Fortress 2.

Unable to open Developer Console

Players with non-US keyboards often encounter problems opening the Developer Console because the set opening key (~) is positioned in a different location. Binding the key via the config.cfg file will not work because the game resets to the default key automatically. Most of the time the console can be opened by pressing the button to the left of the '1' key/under the 'Esc' key. In UK and similar keyboards, this button is the '`' key.

Hosting a listen server

To host a server while playing, one must be able to forward ports and enter a console command. The ports 27015 and 27005, both TCP and UDP, need to be forwarded. Then type in console sv_lan 0 without the quotes. Now click "Play Multiplayer", select the map of your choice, and others should be able to join.

In order for your server to show up on the server list, you must change sv_region to a value corresponding to your region.
