Mapbase Setup Troubleshooting
This article tries to cover common issues encountered by users trying to set up Mapbase. If you cannot find the solution to your problem here, you may be able to find help on Mapbase's Discord server.
Make sure Source SDK Base 2013 Singleplayer is running on the upcoming branch.
Make sure you are placing the Mapbase mod folders inside of the sourcemods folder and the sourcemods folder is in the right place. For example, Steam/SteamApps/sourcemods/mapbase_episodic is a valid directory.
Otherwise, this often has to do with whether you use multiple drives for storing Steam games; you may need your sourcemods folder to be located in the same directory as Source SDK Base 2013 Singleplayer.
This happens when Hammer is launched without a valid -game parameter while using a Mapbase config. Make sure you are using a shortcut to launch Hammer and make sure the shortcut was set up correctly. Please return to the setup page for more information on setting up a shortcut.
This usually happens when multiple linked FGDs are manually included in the Mapbase config. halflife2.fgd includes base.fgd automatically, so you should normally only be using halflife2.fgd in your Mapbase config.
Some mods (e.g. Map Labs) may also have their own FGD which includes both halflife2.fgd and base.fgd, or is just a renamed modification of halflife2.fgd.
Issues like this can happen for many reasons, but if you're setting up Mapbase and you encounter this issue after compiling a map, this is usually because you didn't use compatible compilers.
In order to compile Mapbase maps, you must use either Mapbase's custom compilers or Slartibarty's Slammin' Source mapping tools. See this article for more information on which compilers to use.
Issues like this can happen for many reasons, but if you're setting up Mapbase and you encounter this issue the first time you try to compile a map, it's usually because you put the map compilers in the wrong place.
In order to work properly, custom map compilers must be in the same bin folder as Hammer because they depend on the adjacent .dll files. It's recommended that you back up the original compilers before overwriting them. Make sure your custom game config uses the correct directories as well.
