Mounting a Game
Ensure you have the Source Engine game(s) you wish to mount fully installed and up to date and have ran the game at least ONCE before continuing.

  • Start Garry's Mod (or press ESC) so you can see the Main Menu.


  • Click the controller icon () down the bottom, next to the language icon.

  • Tick which games you wish to have mounted.


  • You may need to Restart Garry's Mod. (Close and Reopen the Game)

  • That's it! You have now successfully mounted the games!

NOTE: Mounting a lot of games may cause slower start up times and slower connection times to servers. It is recommended you only mount what you need.

NOTE: Only Source Engine games which have been approved and set up by Garry will appear on the list. Example. Warframe is not Source Engine: so it will not be on the list.

A game isn't working, or I see purple checkerboards, weapon or world models are missing, or experience crashes while playing a game - how can I verify that my game files are installed correctly?

I don't support pirating games and stealing from developers of their hard earned time. If you're that desperate to save a few dollars, you can download most textures and stuff off the Steam Workshop.

@ohyeahjucie

I bet Steam would detect it as pirated, and delete the files. Also, why would you want to go through that pain when people provide other textures online?

I have tf2 installed and the maps load in right and most textures work but some textures are replaced with gmod/hl2 textures.

Depends on the game. I believe the only game that gives you weapons is Half-Life: Source.
