    This is a simple script that uses UnrealPak to decompile 4.23 paks and recompile them for 4.26. This automates the conversion process that Yuri/Jonah demonstrated on YouTube. Unfortunately, many mods do not convert so easily and may act broken or crash the game. It seems to work best on mods that focus primarily on texture replacements.

    USAGE:
    This script is particularly useful for batch conversion of .pak files from 4.23 to 4.26. I originally made this for myself to batch convert about 100 TSW2 mods quickly.

    REQUIREMENTS:
    You must have the Unreal Engine 4.26 editor installed, available from the Epic Games Launcher. Everything else is included.

    INSTRUCTIONS:
    1. Install UE4.26 Editor from Epic Games Store
    2. Locate the path of UnrealPak.exe, e.g.: "C:\Program Files\Epic Games\UE_4.26\Engine\Binaries\Win64\UnrealPak.exe". Location will vary depending on where you choose to install the Editor.
    3. Open "4.23_to_4.26_converter.ps1" with any text editor and replace the directory specified by $UnrealPak with your own directory. Make sure to save your changes. BY DEFAULT, THE SCRIPT WILL POINT TO "C:\Program Files\Epic Games\UE_4.26\Engine\Binaries\Win64\UnrealPak.exe"
    4. Run "4.23_to_4.26_converter.ps1" with PowerShell. You may need to run with Administrator privileges.
    5. Let the script complete fully, which make take a while. You will find all converted .pak files in a folder called "newpak".


    NOTES:
    There may be unintended consequences by converting mods directly from 4.23 to 4.26, particularly with sound mods, and some may not work at all. If so, they might need to be redone from scratch by the original creator. MANY CONVERTED MODS WILL CRASH THE GAME, so pay attention to which ones do and don't work.

    Brilliant work, many thanks. It's a shame 4.23 sound and blueprint mods won't work, I hope we don't lose too many of them.

    Updated to remove QuickBMS dependency. Now uses UnrealPak for decompilation.

    Cheers

    Unlikely since it is a blueprint mod. You will have to wait for the mod author to manually remake it.
    Yes.

    I know this is a stupid question and it probably will not work.

    But do you think we could use this to Recompile NEC: New York for 4.26?
    And if so, how would the game react to it?
    Would it crash entirely?
    Would the route show in Route List?
    Would it play and work?
    Would it get to a Somewhat Playable state?

    I will be trying this over the next few weeks

    I know this is a Stupid Question, but its worth it

    He means the link to the converter mod not the link to NEC and only DTG could make NEC work in TSW2 as you need the original uncooked game files, and theyve said its not going to happen.
