Before content can be imported into Source Filmmaker you need to extract the components from the content packages located within the Steam folder. To do this load GCFScape[nemesis.thewavelength.net]
and go to File > Open.
Navigate to your Steam folder and look within the following directories for both GCF and VPK files, these are the packages which contain content for Source engine games.
If you're looking to use content from a game which uses a VPK format, you'll need to open the main VPK file typically named pak01_dir.vpk
. Keep in mind that games using the VPK file format do not usually store maps within the VPK, which means you don't need GCFScape to extract them.
With the content package open in GCFScape, select the folders you want to use and right click on them. Choose Extract
from the drop-down menu. Whenever you're extracting content from GCFScape it's advised to keep the folder structure intact.
Navigate to the game
folder within the Source Filmmaker directory. This can typically found here:
Create a new folder within the game
directory and give it a name which you can use to identify the content. In my example I'm extracting Portal 2 content, so I named it portal2
Once you click ok
the content will begin extracting to the designated folder. This process can take a while depending on the amount of content being extracted.
