Last Updated: 3/6/24 Adding a workshop collection to your GMod server is a crucial step. By adding a workshop collection to your GMod server, players don’t need to manually go to your Steam Workshop page to download the addons. This saves your players lots of time, and makes it so that everyone on the server has all the addons needed to play. Follow the steps below to add a collection.
1

Launch the Steam client on your desktop.

If you’re not a current Atomic Networks client, claim your Free GMod Server Hosting to get started on a GMod server for your favorite gamemode in less than half an hour. If you’re already hosting with another GMod service, see how we offer way more performance for less.

Create a workshop collection.

Navigate to the Create a Collection page. This is under the Steam Workshop category.

Find the GMod addons you want to add.

Once you have found an addon you want to add to your server, click the Add to Collection button.
5

Change the visibility of your Workshop collection.

Go back to your workshop collection page, make sure your collections’ visibility is either Public or Unlisted. We highly recommend keeping your workshop collection public. Players might want to manually go and download your Workshop addons from your server’s collection page.
6

Generate a Workshop ID for your GMod Workshop collection.

Now we will be adding your workshop page’s addon collection to your GMod server. On the Workshop Collections page, right click anywhere and select “Copy Page URL”Paste your link anywhere on your computer and take out the Workshop ID.
Example: When doing this step, the link https://steamcommunity.com/sharedfiles/filedetails/?id=2901076879 becomes 2901076879. 2901076879 is the workshop ID in this example.

Paste the Workshop ID into the Atomic Panel.

Once you have your Workshop ID, paste it into the Workshop ID textbox. If done correctly, your server will have your workshop addons.

Restart your GMod server.

Once you have added your workshop collection, restart your GMod server for the workshop addons to work.
