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
- Go to Steam Workshop for Garry’s Mod.
- Find the desired map (e.g.,
rp_evocity_v4b1
,gm_construct_extended
, etc.). - Click "Add to Favorites" or remember the name.
🧩 Step 2: Create Your Collection
- Go here: Create a Collection.
- Click "Create New Collection".
- Enter a name, description, select category
Garry's Mod
and check "Maps". - After creation — add your chosen map and any needed addons.
- 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
- Go to the control panel.
- Open the Startup Settings tab.
- Find the
Workshop ID
field. - Enter your collection ID there, for example:
🔁 Step 4: Set the Map in Startup Settings
- In the same Startup tab.
- Find the Map field.
- 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:
- Click "Restart" in the panel.
- Wait 30–60 seconds.
- 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.
