Как изменить vpk

VPK (Valve Pak) files are uncompressed archives used to package game content. Valve’s post GCF games store materials, models, particles, choreography scenes and many other file types in VPK files.
VPKs are also used to distribute mods via the the addoninstaller tool that ships with some games, such as Left 4 Dead 2.

Creation

VPKs can be created with the command line tool vpk.exe.

The tool can be located in the bin folders for most Source games, such as the ones below. The tool is not game dependent, however it is suggested that you use the tool that corresponds to the game you are creating the vpk for. The version in one game may not be as up to date as the version in another due to game updates.

Game	Path to VPK.exe
Alien Swarm	..steamappscommonAlien Swarmbin
Team Fortress 2	..steamappscommonTeam Fortress 2bin
Left 4 Dead	..steamappscommonLeft 4 Deadbin
Counter-Strike: Source	..steamappscommonCounter-Strike Sourcebin
Source	..steamappscommonSource SDK Base 2013<Singleplayer or Multiplayer>bin
Counter-Strike: Global Offensive	..steamappscommonCounter-Strike Global Offensivebin
Portal 2	..steamappscommonPortal 2bin

 Bug: For some reason sometimes when vpk.exe is used to extract VPKs it gives empty folders, Portal‘s vpk.exe

(..steamappscommonPortalbin) seems to extract the files fine

(there might be a corruption when used since it is a diffrent version).

For servers installed using SteamCMD, it is located in the server’s bin directory. On Linux, it is named vpk_linux32 instead of vpk.exe.

Linux / Unix

Note: The vpk binary makes VPK files of version 2.0, which are not compatible with games like Left 4 Dead 2 that use an older version of the VPK format (in fact Left 4 Dead 2 will not even start if it detects an unsupported vpk). There is a Python package that can be installed with

which supports the older format. It is also far more convenient than using the built-in tool. Instructions can be found on the Github page.

On Linux / Unix clients, the vpk file can be found replacing «..steamappscommon» for «~/.steam/steam/steamapps/common/«. However, it is named vpk_linux32 instead of vpk.exe. Note: If you installed Steam via Flatpak, the path is slightly different. Look in ~/.var/app/com.valvesoftware.Steam/.local/share/Steam/steamapps/common

If you are running on a 64-bit system, this binary will not work by default. You must tell it to use the 32-bit libraries located in the same directory. This can be done by setting the LD_LIBRARY_PATH variable.
The following script, if created in the above listed bin directories, will create a wrapper to properly launch the 32-bit executable; then a link (or desktop shortcut) to vpk.sh (if saved as said name) can be created, from there:

#!/bin/bash
DIR=$(dirname "${BASH_SOURCE[0]}")
export LD_LIBRARY_PATH=$(cd "$DIR" && pwd)
exec "$DIR/vpk_linux32" "${@}"

Alternatively, if you’re running 64-bit Linux, you can use this script to execute the vpk_linux32 binary successfully. Save this script to «/usr/local/bin/vpk» and set it as an executable in the file’s properties, for ease of use:

#!/bin/bash
VPK_LINUX=$(find "${HOME}/.local/share/Steam" -type f -iname "vpk_linux32" -print | head -n 1)
VALVE_LIB_DIR=$(dirname "${VPK_LINUX}")
LD_LIBRARY_PATH="${VALVE_LIB_DIR}:${LD_LIBRARY_PATH}" "${VPK_LINUX}" "${@}"

HELPFUL NOTE: The «${@}» is for drag-and-drop with *.desktop files and arguments when using the vpk command via console.

Windows

On Windows, you can easily drag-and-drop folders onto vpk.exe file in the bin folder and get a *.vpk file in return, and vice-versa by drag-and-dropping a *.vpk file instead.

 Tip: Some users may find it easier to create a shortcut (*.lnk) linked to vpk.exe as it can be placed anywhere, like a folder that you often are packaging files from, making packaging folders into VPKs and vice-versa quicker and easier than having to return to the bin folder to do so. A good example of this is the custom folder, where placing a shortcut there could make debugging of custom vpk files much quicker.

Commands

Usage

vpk [options] <command> <command arguments...>

vpk [options] <directory>

vpk [options] <vpkfile>

Example

vpk -?

Lists all of the help info, list of available arguments, and info about each argument.

Create VPK/Add Files

vpk <dirname>

Creates a pack file named <dirname>.vpk. Must be an existing location. The VPK will appear next to the directory.

 Tip: Drag a folder onto the tool in Explorer to trigger this command.

vpk a <vpkfile> <filename1> <filename2> ...

Add file(s).

a <vpkfile> @<filename>

Adds the files referenced in a «response file» (not response rules). Note the @ symbol.

The added file will not be added with its file path if the default file path matches that of CMD

k vpkfile <keyvalues_filename>

Add files references in a keyvalues control file.

 Bug: They will appear inside the VPK with their full path (C:etc) intact — is there a way to avoid this?

vpk <directory>

Create VPK from directory structure.

 Note: This is invoked when a directory is dragged onto the VPK tool.

vpk x <vpkfile> <filename1> <filename2> ...

Extract file(s).

vpk <vpkfile>

Extract all files from VPK.

 Note: This is invoked when a .VPK file is dragged onto the VPK tool.

Display VPK Info

vpk l <vpkfile>

List contents of VPK.

vpk L <vpkfile>

List Detailed contents of VPK.

VPK Integrity/Security

vpk checksig <vpkfile>

Verify signature of specified VPK file. Requires -k to specify key file to use.

Misc.

vpk generate_keypair <keybasename>

Generate public/private key file. Output files will be named <keybasename>.publickey.vdf and <keybasename>.privatekey.vdf

 Note: Remember: your private key should be kept private.

Options

 Tip: Please note the case of these options. A capital letter is different than a lowercase letter.

-v

Verbose output.

-M

Produce a multi-chunk VPK.

 Note: Required if creating a VPK with key values.

• Each chunk is a file limited to around 200MB.
• To reduce patch sizes, chunks are never overwritten. New/modified files are instead written to a brand new chunk every time you run the tool.

   Note: Multi-chunk generations only works when creating a VPK from a response file.

   Tip: To inspect a multi-chunk VPK open the ‘_dir’ file.

-P

Use SteamPipe-friendly incremental build algorithm. Use with ‘k’ command. For optimal incremental build performance, the control file used for the previous build should exist and be named the same as theinput control file, with ‘.bak’ appended, and each file entryshould have an ‘md5’ value. The ‘md5’ field need not be theactual MD5 of the file contents, it is just a unique identifierthat will be compared to determine if the file contents has changedbetween builds.

-c <size>

Use specified chunk size (in MB). Default is 200.

-a

Align files within chunk on n-byte boundary. Default is 1.

-K

With commands ‘a’ or ‘k’: Sign VPK with specified private key.

-k

With commands ‘a’ or ‘k’: Public key that will be distributed and used by third parties to verify signatures.

With command ‘checksig’: Check signature using specified key file.

Examples

Listed below are some examples of using the tool and what they will do.

Making custom vpks for a mod

Content must be a subdirectory under sound/materials/models in the root dir of your VPK, or else they won’t appear in hammer.
IE your sounds should be located in sound/foo/thisIsASound.wav in your custom vpk, models under models/, materials under materials/, etc.^[Clarify]

VPKs must be mounted in gameinfo.txt.

Creating A Key Value File and VPK

1. Create a folder with the correct directory structure and files that you wish to use such as mymod/resource/ui/<file.res>

2. Use the command line in a prompt or a bat:

vpk generate_keypair <name>

vpk -M -k <name>.publickey.vdf -K <name>.privatekey.vdf "..SteamAppscommonTeam Fortress 2binmymod"

3. In the folder where the vpk tool is located there will now be a public key vdf, a private key vdf, a vpk named mymod_000 and a vpk named mymod_dir.

 Warning: Never disclose or share your private key vdf or the key. Only share the public key.

• You must distribute your mod with both the mymod_dir and mymod_000 vpks for the keyvalue to work.

Response File

A «response file» contains a list of files to be added to a VPK. Paths are relative to the current directory of the vpk tool.

Below is a Python script which generates a response file and then builds a multi-chunk VPK. Put it in your mod folder. You will need to edit the three variables at the top.

#What folders to look for, and pack into the pak01 vpk set.
target_folders = [ "materials", "models", "resource", "media", "particles", "scripts", "maps", "expressions", "scenes" ]
#What files to look for, in the aforementioned folders.
file_types = [ "vmt", "vtf", "mdl", "phy", "vtx", "vvd", "ani", "pcf", "vcd", "txt", "res", "vfont", "cur", "dat" , "bik", "mov", "bsp", "nav", "lst", "lmp", "vfe" ]
#which vpk.exe to use. do not use !
vpk_path = "../steamapps/common/SourceFilmmaker/game/bin/vpk.exe"

# Script begins
import os,subprocess
from os.path import join
response_path = join(os.getcwd(),"vpk_list.txt")

out = open(response_path,'w')
len_cd = len(os.getcwd()) + 1

for user_folder in target_folders:
	for root, dirs, files in os.walk(join(os.getcwd(),user_folder)):
		for file in files:
			if len(file_types) and file.rsplit(".")[-1] in file_types:
				out.write(os.path.join(root[len_cd:].replace("/","\"),file) + "n")

out.close()

#the "pak01" here specifies the multi-chunk vpk names. Could be changed to "pak02" or "hl2_textures", or whatever your mod needs.
subprocess.call([vpk_path, "-M", "a", "pak01", "@" + response_path])

To handle this process for Portal 2 you can also use the P2 Multichunk Tool, to automate the response file creation and the creation of the vpk files.

 Warning: The tool will probably work for other games aside Portal 2 if you change the .vpk path accordingly, I have expanded it’s functions to make it easier to experiment, but, since I haven’t tested outside Portal 2 I can’t 100% guarantee it will work with other games, feel free to test it, and please let me know if it works.

Excluded files

Executable and some archive files are discarded by the VPK tool:

.zip .reg .rar .msi .exe .dll .com .cmd .bat

 Warning: Other VPK files are not excluded from compilation, and will be compiled into the new VPK if present in the search paths!
