Extra: Adding custom content

Custom content works almost identically to the addon format in Gmod. You don't need to create the vpk if you want to constantly edit the contents of the "addon". Create a folder, name it whatever you want, and put the materials folder, sounds folder, and models folder in there. (in the custom folder of course) If you are mounting other people's addons, a vpk would be the way to go.If you want to add custom content, like sounds, models, materials and the like, you have to go into the VPK Creator in Source Multi Tool.You don't have to edit the game that the VPK is for, or the file size per VPK, but you can set it up high if you don't want multiple VPKs for models, or textures, or whatever.Create a file wherever you wish, and name it what you want the VPK to be called.In this case, I will be mounting content from an addon (That I got FULL PERMISSION) to download the contents of), that contains models from the Half-Life 2 Beta. In the file you just created, put in the materials, models, and sounds folder. Now take the file and drag in on to Victor's face. It will now being to pack the files.When its done, take the VPK it just generated, and put it into this folder:C:\program files (x86)\steam\steamapps\common\Source SDK Base 2013 Multiplayer\CustomConfig\customYou have successfully added custom content.
