What's new in OpenIV 2.9.2:
First time since 2015, we have updated OpenIV.ASI – our plugin, which provides mods support for Grand Theft Auto V. The latest version of GTA V has some non-critical changes in the code, which is affected by OpenIV.ASI, and we made similar changes in our code. Without those changes in OpenIV.ASI, your game had crash during loading screen in some very specific scenario, only when you have Simplified Chinese language selected in game. Use ASI Manager to update OpenIV.ASI in your game folder.
We fixed an issue where sometimes OpenIV crashes while renaming folders inside archives.
We fixed an issue where import of texture image with 2×2 sizes was impossible due to infinite loading.
We fixed an issue where files were not shown in OpenIV after they were drag-and-dropped in game folder using Windows File Explorer.
What's new in OpenIV 2.9.1:
Open folder: You now can open folders the same way as archives. Use menu “File > Open folder…” and select folder you want to open. The selected folder will appear at the end of the list in the navigation tree.
Delete confirmation dialog: OpenIV will now show you delete configuration dialog, it will help you to avoid accidental removal of game files. You can disable this feature in OpenIV configuration.
Grand Theft Auto V
We added support for carvariations.ymt file
We added support for vfxvehicleinfo.ymt file
You can edit those files using the inbuilt OpenIV Text editor or export them to META/XML format.

We fixed an issue where wrong High Level Code was generated in SCO Viewer.

We fixed an issue where it was impossible to use context menu on travel buttons (Back/Forward) when history list contain many items.
We fixed an issue where some users might get “Unable to initialize Windows DirectX subsystem” fatal error message.
We added the ability to use keyboard arrow keys to navigate through shaders information in models viewer.
We made minor visual changes in “More information” dialog in models viewer.
We fixed an issue where users might see “Confirm edit mode” dialog while creating archive in edit mode.
We changed keyboard shortcut for creating new archive from “Ctrl + N” to “Ctrl + Shift + N”.
We added the ability to use “Ctrl + N” keyboard shortcut for creating new archive in current location (Same as “Ctrl + D” for folder).
We fixed an issue where status bar does not update when items are added or removed.
We fixed an issue resulting in unexpected behavior when double-clicking on group header in file list.
You now can use “Shift + Delete” keyboard shortcut for permanently deleting files while using Recycle Bin (This works for files on disk not for files in archives).
We fixed an issue resulting in “Edit mode” button become disabled in specific scenario.
We improved support for Junctions or Symbolic links. You now will be able to use global search while your game folder is Symbolic links.
We changed the way how Size column is displayed in file list. Now it works just like Windows File Explorer.
Some more changes were made, they are minor or are not worthy of mention.

Just put archive (for example, x64a.rpf) you want to mod into “mods” folder and made changes in that copy. OpenIV.ASI will force game load your archives form “mods” folder.

Finally, OpenIV fragment models viewer got support of GTA V .yft files. This will allow you to view GTAV vehicles models.
Critical bug fixed
We also have fixed some critical issues in our code. Now you have less chance to corrupt your files.
Open IV for PC version of GTA 5 is an editor with many features. Thanks to this editor, the player has ample opportunities for editing textures, models, texts and, in general, all game files - it all depends on your level of knowledge about modding. Also, Open IV is required to run some add-ons.
Starting with version 2.6, the developers have significantly increased the scope with which you can interact:
Version 2.6
- Added access to edit files.
Version 2.6.3
- Fixed critical errors and program freezes.
- Fragments Models Viewer is an application thanks to which you can look at transport models in gta 5 with *.yft extension.
- Texture Editor is a very powerful texture editor that makes it possible to edit *.yfd texture files.
- Open IV.ASI 1.1 - Now the original game files will be safe, because all add-ons are now stored in a separate folder - "Mods". It is enough to move the add-on file to the mods folder and start the game, then the editor will do everything by itself and GTA 5 will start with all the modifications made. If suddenly you want to run the game without add-ons, just remove Open IV.ASI and ASI Loader using ASI Manager.
- ASI Manager is a manager that will help you uninstall or install ASI Loader and related plugins.
Version 2.6.4
- Audio Editing - editing of *.awc files is now available, which is an audio recording of the sounds of weapons, vehicles.
- Audio export – adds the ability to remove *.wav audio recordings from the game.
How to use OPEN IV for GTA 5
- Download and install Open 4 for GTA 5.
- After the initial launch, configure the program to work with your copy of the game.
- Go to Tools (Tools), then to ASI Manager or use the ASI Manager button on the toolbar.
- Install ASI Loader and OPENIV.ASI.
- Go to the root directory of the game and create a new folder there called “mods” (name without quotes, letters in lowercase).
- Next, transfer the archives of modifications with the RPF extension to the mods folder. For example, if you need to modify the update/update.rpf archive, the path would look like this: Grand Theft Auto V/mods/update/update.rpf
- If you need to return to files with original characteristics, then simply delete OpenIV.ASI through ASI Manager. Thus, there is no need to constantly edit game resources by deleting the mods folder.
Finally, after almost a year and a half of waiting, the gaming community has waited for the moment when it became possible to create and install custom modifications on GTA 5. Some of them are installed by simply adding files to the root folder of the game, however, for a huge number of modifications, you need to change files in the game archives, which cannot be done without using special programs. One of these programs, and perhaps the most convenient, is Open IV. This super useful tool will allow you to easily edit the hidden archives of the game, add and modify files in them and all you have to do to get all these features at your disposal is to download Open IV. Other than that, Open IV is a very handy and probably indispensable tool for modding.
Imagine, for example, that we need to install a texture that replaces the default weapon model. How can we do this without OpenIV? Of course, no way, but with the help of Open 4 we can do it in two clicks. With the same success, you can easily add new files and folders to the archives of the game, which provides the widest scope for modding and allows you to do almost anything with the game. It's safe to say that Open 4 is an absolute must-have for any fan of GTA 5 mods.
We suggest you download the latest version of Open 4 from our website.
How to use Open IV
Click on the OpenIV icon to launch the program, select GTA 5, then your system, and wait for the download to complete.
You have entered the program menu. Everything here is similar to the standard explorer, allowing you to see all the files, archives and folders in the root directory of GTA 5. You can freely move around, open any archive, however, in order to modify or rebuild archives, as well as add or delete files, you need to turn on the mode editing, as shown in the screenshot.
Then follow the instructions for installing your modifications. Most often, you just have to replace the texture or script files, much less often you have to add new folders and files to the game archives. In any case, the first rule of using OpenIV is to make backups of all files you replace. In edit mode, the program automatically saves all the changes you have made, so if you do something wrong and the source files are not at hand, then GTA 5 will have to be reinstalled.
That's all, now you can easily install any modification, for this you only need to use the excellent Open 4 program.
