Bug:Left 4 Dead-style addons do not work in Portal 2 if DLC folders or the update folder are present. This effectively makes them unusable as a way to distribute addons, as the average user will not have their install modified to remove these. Consider releasing your map on the workshop instead or using DLC folder overrides.  [todo tested in ?]

Now that you have made your brilliant map you need a way to get this out to the public. If your map happens to have custom content such as sounds, scripts and materials the best way to release it is putting it inside a VPK. This collects all of your content into a single file and makes it easy to distribute.

Creating the VPK

1. Create a folder and label it with your addon name.
2. This folder should now mimic the structure of the 'Portal 2\portal2\' folder.
3. Start with adding a folder called maps and add in your compiled .BSP.
4. If you have any scripts be sure it lies in the same relative folder inside scripts\vscripts.
5. The same applies for sounds and materials.
6. Inside 'Portal 2\bin\' there is an executable called 'vpk.exe'. Drag your folder you created in step 1 onto this executable.
7. You will now have a .VPK file in the same folder with the same name.

Tip:As an added convenience, a folder can also be dragged onto a shortcut of 'vpk.exe' (provided in Portal 2) in any location.

Tip:Because of the bug you can also rename the vmf file pak0#_dir.vpk (make sure you don't use the number 1 for valve is already using it) and put it in the common\portal2\portal2 folder or any of the portal2_dlc folders.

Installing the VPK

Note:If you have the Sixense MotionPack DLC, you will most likely have to create the folder in 'Portal 2\portal2_sixense.'

1. Create a folder in 'Portal 2\portal2\' called addons.
2. Place your .VPK file inside the addons folder.
3. If Portal 2 was running during step 2, type the following in the console: update_addon_paths. Otherwise, skip to the next step.
4. To load a single player map, type in the console: map mymap and replace mymap with the name of your map.
5. To load a Co-op map, start a Co-op game with your friend, once you enter the hub type in console: changelevel mymap replace mymap with the name of your map.
