To download friends mods on Gmod, the fastest way is to join their server directly from the multiplayer menu, Garry's Mod will automatically pull and install every Workshop mod that server uses. You don't need to search for each addon individually; just connect, wait for the progress bar to finish, and the game handles the rest for you.
How to download friends mods on Gmod automatically
When you join a friend's server through the in-game multiplayer browser, Gmod automatically checks which Workshop addons the server is running and downloads any that you don't already have. This is the cleanest method because it ensures you get the exact versions your friends are using, with no guesswork about which mods are needed.
To trigger this, open Garry's Mod, click Multiplayer, then select the Friends tab to see servers where your friends are active. Pick the server and click Join. As the game connects, you'll see a download progress bar appear, this is Gmod fetching all required Workshop content. Let it reach 100% before you spawn in. If the bar stalls, you can usually rejoin the server to resume the download.
This automatic process works for any mod hosted on the Steam Workshop, including maps, weapons, models, and scripts. Once the download completes, the mods are installed and active, no extra steps needed. If you need new environments to explore, you can also download gmod maps the same way. Just make sure your Steam client is running and logged in, because Gmod relies on Steam to fetch Workshop files.
How to manually install mods your friends share
Sometimes your friends use mods that aren't on the Workshop, custom files they've created or downloaded from external sources. In that case, you'll need to install them manually. The process is straightforward: get the mod files from your friend (usually as a compressed folder like a .zip or .rar), then extract them into the correct directory.
Here's what to do:
- Locate your Garry's Mod installation folder. In Steam, right-click Garry's Mod in your library, select Manage, then Browse local files.
- Open the folder named garrysmod, then open the addons folder inside it.
- Extract the mod files you received directly into the addons folder. Each mod should be in its own subfolder, don't dump loose files into the root.
- Restart Garry's Mod completely after extraction so the game scans and loads the new addons.
After restarting, the mods will appear in your addons list and be available in-game. This manual method is essential for mods that are still in development, private creations, or content hosted outside the Workshop. If your friend shares a folder, make sure you copy the entire folder structure, not just the files inside, so Gmod recognizes it correctly.
Why your friends’ mods might not work and how to fix it
Even after downloading, you might run into issues where mods don't work correctly. The most common symptom is missing textures, you'll see pink and black checkerboard patterns instead of proper models or surfaces. This usually means a mod didn't download completely, or the version you have doesn't match what the server expects.
Here are the typical problems and their fixes:
- Missing textures (checkerboards): This happens when a mod file is corrupted or incomplete. Unsubscribe from the mod in the Steam Workshop, then resubscribe and rejoin the server. If it's a manual install, delete the mod folder from addons and re-extract it fresh.
- Version mismatches: If your friend updated a mod but you still have the old version, the server may reject it or show errors. Check the Workshop page for recent updates and make sure your subscription is current. For manual mods, ask your friend for the latest files.
- Broken downloads: Sometimes Steam's download cache gets corrupted. Restart Steam, verify the integrity of Garry's Mod files (right-click the game in Steam, select Properties, then Local Files, then Verify integrity of game files), and try joining again.
If you're still seeing pink and black checkerboard textures after these steps, the issue is almost always a missing or outdated addon. Rejoining the server after resubscribing forces Gmod to re-download everything the server needs. For manual mods, double-check that the folder structure in addons matches what the mod creator intended, a misplaced file can cause the entire addon to fail.
Testing mods together with friends
This lets you confirm everything loads correctly without the pressure of a live multiplayer session. Launch Garry's Mod, select Start New Game, pick any map, and spawn in. The mods you've installed will be available immediately, check that weapons, models, and maps appear as expected.
Go back to the addons menu (under Options then Addons) and make sure the mod is enabled.
Once everything looks good in single-player, rejoin your friend's server. You should now see the same content they see, with no missing models or error messages. Testing together also helps you spot any lag caused by heavy mods, if the game stutters, consider disabling a few addons or asking your friend to trim the server's mod list. Playing with matching mods ensures a smooth experience where everyone sees the same world, and you can fully enjoy the custom content without interruptions.
