How to Upload a Hammer Map to the Workshop

Overview

This is a guide showing you how to upload a Portal 2 Hammer Map to the Steam Workshop

Triggering the Vote Screen

The first step to upload a Hammer map to the workshop is to have the vote screen trigger at the end of your test. To get the end screen to trigger you have to follow most of these steps.

1. Open global_pti_ents.vmf in hammer.
   (which is in SteamsteamappscommonPortal 2sdk_contentmaps).

• @glados

Uploading your Map

1. To begin you must download the Portal 2 Authoring Tools – Beta, but I assume you have already because that’s how you get the Portal 2 Hammer.
2. To upload your map you have to find p2map_publish.exe

3. Open it and you will be greeted by this menu. As you can see I have already uploaded a map.
   
4. Add will let you upload a new map, Delete will delete it from the workshop, Edit will let you update a pre-existing map, and Refresh will refresh the list of maps on your workshop.
5. When you click on Add this menu will pop up:
