AURORA CAK FOUNDRY / THE SIMPLE VERSION
CAK Foundry is the tool inside AuroraForge NT100 that reads your game's CAK archives and writes your own mod CAK. This page walks through it once, in order, with a picture at every step.
Read the archive. Copy the files you need into your own folder. Check your mod in game before you ship it. AuroraForge NT100 uses the Oodle library already included with your installed game, it does not bundle game files, and it never writes back into your original CAK archives.
PART ONE / OPEN IT AND FIND YOUR GAME
CAK Foundry lives inside the main app. Open it, tell it where your game is installed, and wait until it says it is ready.
In AuroraForge NT100, click Inspect & Convert in the sidebar, then choose CAK Foundry. You land on the Aurora CAK Foundry page.
Everything happens inside this one window. There is no command line and no extra download.
Set Game version, then click Choose Game Folder and pick the folder that contains WWE2K26_x64.exe. It is usually under SteamLibrary\steamapps\common\WWE 2K26.
PART TWO / CHOOSE AN ARCHIVE AND READ IT
A CAK is the game archive that holds the assets. CAK Foundry lists the archives it found, then shows you every file inside.
The Archives found in your game folder list shows every CAK it found, with its size. Choose one, or click Browse for CAK if the archive is somewhere else.
Click Open Selected CAK to read the archive you chose. Click Open All Game CAKs to combine every CAK in the game folder into one searchable browser.
When it is ready you will see the file count, the folder count, the expanded size, and how many files are ready to extract.
Search by name, hash, or type. Use the Ready files filter and the All file types filter to narrow it down. Tick the box next to any file to select it. Use PREVIOUS and NEXT to move through pages.
PART THREE / COPY FILES OUT
Extraction writes a copy into a folder you choose. The CAK itself is never changed.
Check the files you want. Scroll to the bottom of the panel and pick the folder the copies should go into. Use a folder of your own, for example Documents\AuroraForge\Extracted.
There is also Extract All CAK Files if you truly want the whole archive. It is huge, so use it on purpose.
A small box asks: Extract 2 selected file(s) into the separate output folder? The CAK will not be changed. Click OK.
If you are not sure about a file, cancel and check the name first.
The counts update when it is done. Your files are in the output folder you picked. Open that folder and check that the files look right before you use them.
This is the Check part of the rule: look at what you copied.
PART FOUR / BUILD YOUR OWN CAK
This part takes a folder of extracted, edited files and packs it back into a CAK your game can load.
Click Choose BakeMe Folder and pick the folder that holds your extracted and edited files. AuroraForge NT100 excludes that folder's own name and rebuilds its contents as a protected WWE 2K26 FDIR archive.
Click Save BakeMe Folder. In the Save box, give the file a .cak name and pick a save location outside your BakeMe folder.
The build runs the same toolchain the app uses. When it finishes you will see AuroraForge NT100 CAK rebuilt successfully and Ready to use.
Your new CAK is a separate file. The game archives are still untouched.
The error Save the new CAK outside the selected BakeMe folder is not a broken build. It means the save location was inside the folder you are rebuilding. Pick a different folder, such as Documents\AuroraForge\Mods, and run it again.
Most problems are a wrong folder choice or a save location, not a broken tool.
Pick the folder that contains WWE2K26_x64.exe itself, not the folder above it. If you use Steam, open Steam, right-click WWE 2K26, choose Manage, then Browse local files.
Confirm the game version and the folder, then choose the folder again. If you moved the game, point CAK Foundry at the new location.
That library ships with the game. Make sure you chose the real game folder, and that the game files are still installed and not moved to another drive.
A full CAK can hold tens of thousands of files and many gigabytes. Search for the file you need and extract only that.
Save the new CAK in a different folder, for example Documents\AuroraForge\Mods, then rebuild again.
No. CAK Foundry reads your game archives and writes new files in folders you choose. It never edits the archives in your game folder. Stage and test your mod with the loader before you play with it.
