Portal - SDK - Premade Facrications (Prefabs) file

Frequently Asked Questions (FAQ)

This pack contains a folder with 52 different prefabs to make it easier and faster for you to create your own levels / puzzles from scratch within the hammer editor, also known as Worldcraft.

To use these for yourself, go into your Steam library, right click on 'Portal' and then properties. From there
navigate to the 'local files' tab at the top of the window that pops up and afterwards click on the 'browse local files' button.

The windows file explorer should now open from which you should move into the 'bin' folder where within you should copy the prefabs folder to, which follows with this download as mentioned above. The prefabs can now be used next time you open or create a new level within hammer by the 'new objects' window by selecting the category 'prefabs' instead of 'primitives'. Make sure to always use the global entities prefab in your level, as some prefabs might depend on it. The arena map can be opened from file->open in the top menu bar of hammer.

Since this game is pretty old it does not have an implementation for the newer Steam feature being the Steam Workshop and therefore the only places to release your content are on third party websites:
