inZOI ModKit Packager

A GUI wrapper around Unreal Engine's Automation Tool (RunUAT) for cooking and packaging inZOI mods using the stripped inZOI ModKit. Built with Python 3 + tkinter + sv_ttk and distributed as a standalone Windows executable via PyInstaller.

Building from Source

Prerequisites

• Python 3.10 or later (added to PATH)
• pip

Steps

1. Open a terminal in the source/ folder.

2. Install dependencies:

   pip install -r requirements.txt
   pip install pyinstaller
   

3. Run the build script:

   build.bat
   

   The script performs four steps:

   1. Upgrades pyinstaller, sv_ttk, and Pillow via pip
   2. Runs _make_icon.py to generate icon/Inzoibuild.ico from the source PNG
   3. Runs PyInstaller with inZOI ModKit Packager.spec to produce a --onefile --windowed EXE
   4. Writes the EXE to output\inZOI ModKit Packager.exe

   A full build log is saved to build_log.txt.

Manual PyInstaller invocation

If you prefer to call PyInstaller directly instead of using build.bat:

python _make_icon.py
pyinstaller "inZOI ModKit Packager.spec" --clean --distpath output

Running from Source (no build)

pip install -r requirements.txt
python modkit_packager.py

The app detects whether it is running frozen or from source and adjusts asset and settings paths accordingly.
