How to open gma files

The GMA file format is a package format. It contains the Garrys Mod game content (materials and models). You get this file when you subscribe an addon from Garry’s Mod.

You’ll find this files by default in:
C:\Program Files (x86)\Steam\steamapps\common\GarrysMod\garrysmod\addons

First – you don’t need a thirdparty tool to unpack a GMA file. The extraction tool is a part of the Garry’s Mod game installation: gmad.exe

Create a shortcut to the tool gmad.exe, found (by default) in
C:\Program Files (x86)\Steam\steamapps\common\GarrysMod\bin

Step 1:
Create a new folder

Step 2:
Find the addon you want to extract and copy the gma-file in your folder

Step 3:
Drag the gma file on your gmad.exe shortcut.

A command prompt run and the selected addon file should be extracted in a new folder, with the name of the extracted workshop addon.

Now you can decompile the model-files (found in the folder ‚models‘) and import them in a 3D-tool of your choice.

How to open gma files

Good day. After the new add-on system was introduced, unpacking with old methods became not quite convenient. Half of the add-ons are loaded as before in addons, and the other half in content.

As I understand it, all mods packaged by the new method, namely in .bin, are loaded into content, and then their contents are unpacked into addons. At the same time, the mods remaining in the .gma format are not extracted in addons, and remain in the content folder.

It is not clear why this was done so. In this guide, I’ll show you how to conveniently extract mods from the content folder.

I created a console application in C# in Net Core. This application can work on both Windows and Linux systems (In the second, tests have not yet been conducted, so the application will appear a bit later if it is claimed).

Select the language of the installer.

It is advisable to specify a non-system drive, otherwise it will be necessary after installation to change the launch properties to «As administrator»!.

After the first launch, the console application menu appears, but it is too early to get started. After starting the console application, close it after about 2 seconds.

If you created an application icon on the desktop, you can use the context menu. Right-click on the application shortcut and select «File Location» in the list. Or manually open the folder with the installed program.

After you open the folder with the installed program, you will see that there is a «Config» folder there, go into it. There is a file in this folder called «config.json». Open this file with any text editor. In this example, I am using Notepad ++.

After you open the file, you will see three lines with paths there. Customize the paths based on your location of the game Garry’s Mod. Remember to use double slashes «\\».

After you configure the configuration file, you can start working with the application.

There are three menu items in the application.

When you initialize the list of addons, you use an Internet connection to get information about the add-on. After the list is fully loaded, all information about it will appear in the «cache.json» file in the folder with the installed program.

If you suddenly have problems with the list, you can go to the folder with the installed application and delete the file «cache.json», and then download it again using the Internet connection.

You can extract addons by dragging and dropping folders and files from the content folder into the application’s EXE file.

If you mean gmad.exe, that comes with Garry’s Mod. If you don’t mean gmad.exe, there’s no reason not to mean gmad.exe, considering how easy it is to use (literally just drag and drop a gma file onto it and take the contents of the folder it spits out).

Whoops, was editing my comment, and I didn’t realize I had already posted it, so I just took my time with it. So yeah, you may go re-read my comment for instructions if you want now.

How to open gma files

This guide will explain to you how to extract downloaded Workshop items in order to modify them.

GmadExtractor
BSPsource (optional) *Requires Java*
MilkShape 3D (optional)
VTFEdit (optional)
VIDE (optional)

To extract the gma. files you need Gmad Extractor. That’s how it works.

Download the program. Either google it or use my download link:
https://www.media fire.com/file/p2vap0ve9cqtngq/GmadExtractor.zip
Remove the spaces between «media» and «fire», to open the link.
Virus Total (in case you wondering) [www.virustotal.com]

Now to the extraction part:

To modify maps you need BSPsource and Hammer.
Download BSPsource from GitHub [github.com]

Here’s how you do that.

Some maps might be protected of decompiling. There is no way around, as far as I know.
Here is a guide by TopHattWaffle, explaining decompile protection.
https://www.tophattwaffle.com/protecting-a-map-from-decompiling/

Once decompiled, you want to edit your map with the Hammer Editor.
To get Hammer, you need to have any Source Game installed. Hammer will be automaticly installed when you download Half-Life: 2 or similar Source 2006-2011 titles. The program is located here:
C:\Program Files (x86)\Steam\steamapps\common\Half-Life 2\bin\hammer.exe
For other games, it’s basicly the same. Here’s an example for Counter-Strike: Source:
C:\Program Files (x86)\Steam\steamapps\common\Counter-Strike Source\bin\hammer.exe

If you plan packing and releasing your edited addon on the Workshop, you’ll have to use the Gmod Addon Creator V1.16 (GAC)

GAC is a wrapper for both gmad.exe and gmpublish.exe and makes creating, publishing, and updating addons on the Steam Workshop much easier. I’ve also included gacxlib.dll in case you’d like to use it in your own program. (of course, you’ll have to try to figure out how to use my mickey-moused functions) KEEP ALL FILES IN ONE DIRECTORY OR IT WILL NOT WORK.

Requirements:
-.Net Framework 4
-Garry’s Mod

I hope that the guide was somewhat helpful. Please ask me if anything was unclear.

Файл формата GMA открывается специальными программами. Чтобы открыть данный формат, скачайте одну из предложенных программ.

Чем открыть файл в формате GMA

Формат GMA (полн. Garry’s Mod Addon File) – результат генерации игровой утилиты Garry’s Mod, представляющий собой плагин (мод) для контроля и управления персонажами Half-Life2, Counter-Strike: Source, Team Fortres 2, Portal, Left 4 Dead.

Это своего рода песочница-конструктор, где у пользователя появляется уникальная возможность изменять текстуры, размеры объектов, добавлять или удалять конструктивные элементы и.т.д.

Расширение GMA содержит в своей структуре все многообразие данных, полученных в результате пользовательских действий с примитивами и персонажами игровой компоненты. Разработчиком и издателем данной игровой программы является корпорация Valve.

Программы для открытия GMA файлов

Для генерации и форматирования GMA расширения на базе платформы ОС Windows подойдет единственный программный плагин Garry’s Mod. При этом необходимо учитывать версию мода, так как файл, сгенерированный на более ранней версии игровой утилиты, не сможет быть открыт на более поздней.

Формат GMA не адаптирован для других ОС кроме ОС Windows.

Если при открытии расширения GMA возникает ошибка, причины могут заключаться в следующем:

Конвертация GMA в другие форматы

Расширение GMA уникально по своему содержанию и представляет собой набор данных, полученных в результате пользовательских действий с примитивами и персонажами игрового приложения Half-Life2, Counter-Strike и.т.д.

В связи с этим конвертация данного расширения в другие форматы не представляется возможной.

Почему именно GMA и в чем его достоинства?

Приходится констатировать очевидный факт: GMA формат востребован сугубо в рамках локального конструктора объектов различных игровых шутеров. Расширение не поддается конвертации и не востребовано в кругу рядовых пользователей.
