В Source sdk 2013 не распознаются собственные vpk файлы.
Папка test с модом лежит в Steam\steamapps\sourcemods\test.
В этой же папке test_dir.vpk и test_000.vpk

// The code that loads this file automatically does a few things here:
// 1. For each "Game" search path, it adds a "GameBin" path, in <dir>\bin
// 2. For each "Game" search path, it adds another "Game" path in front of it with _<langage> at the end.
// For example: c:\hl2\cstrike on a french machine would get a c:\hl2\cstrike_french path added to it.
// 3. For the first "Game" search path, it adds a search path called "MOD".
// 4. For the first "Game" search path, it adds a search path called "DEFAULT_WRITE_PATH".
// Search paths are relative to the base directory, which is where hl2.exe is found.
// |gameinfo_path| points at the directory where gameinfo.txt is.
// We always want to mount that directory relative to gameinfo.txt, so
// people can mount stuff in c:\mymod, and the main game resources are in
// someplace like c:\program files\valve\steam\steamapps\half-life 2.
// Now search loose files. We'll set the directory containing the gameinfo.txt file
// as the first "mod" search path (after any user customizations). This is also the one
// that's used when writing to the "mod" path.
// First, mount all user customizations. This will search for VPKs and subfolders
// and mount them in alphabetical order. The easiest way to distribute a mod is to
// pack up the custom content into a VPK. To "install" a mod, just drop it in this
// Note that this folder is scanned only when the game is booted.
// We search VPK files before ordinary folders, because most files will be found in
// VPK and we can avoid making thousands of file system calls to attempt to open files
// in folders where they don't exist. (Searching a VPK is much faster than making an operating
// system call.)
// Add the HL2 directory as a game search path. This is also where where writes
// to the "game" path go.
// Where the game's binaries are
// Last, mount in shared HL2 loose files
