How to Install Your Own Map and Addons on the Server

Using Steam Workshop + Mikasa Control Panel​

Adding a custom map is essential for a unique gameplay experience. This is done via Workshop collections, so everything needed loads automatically. Here's how to do it:

🗺️ Step 1: Find and Add the Map to Favorites​

  1. Go to Steam Workshop for Garry’s Mod.
  2. Find the desired map (e.g., rp_evocity_v4b1, gm_construct_extended, etc.).
  3. Click "Add to Favorites" or remember the name.

🧩 Step 2: Create Your Collection​

  1. Go here: Create a Collection.
  2. Click "Create New Collection".
  3. Enter a name, description, select category Garry's Mod and check "Maps".
  4. After creation — add your chosen map and any needed addons.
  5. Save and copy the Collection ID — it’s the number in the URL:

https://steamcommunity.com/sharedfiles/filedetails/?id=123456789
                                                    ↑
                                                    this is the ID

⚙️ Step 3: Add the Collection ID to the Server Startup​

  1. Go to the control panel.
  2. Open the Startup Settings tab.
  3. Find the Workshop ID field.
  4. Enter your collection ID there, for example:

🔁 Step 4: Set the Map in Startup Settings​

  1. In the same Startup tab.
  2. Find the Map field.
  3. Enter the exact map name (without .bsp), for example:

rp_bangclaw

If unsure — check the Workshop page of the map, the filename is usually listed in the description or comments.

🔄 Step 5: Restart the Server​

After making all changes:

  1. Click "Restart" in the panel.
  2. Wait 30–60 seconds.
  3. The server will boot with the new map and load the required addons from the collection.

💡 Tips​

  • Make sure all addons are public. Otherwise, the server won’t be able to download them.
  • Don’t cram 1000 addons into one collection. It’s better to split into 2–3.
  • Test the map locally in singleplayer before uploading it to the server.
