"Life Modding finds a way."
A simple GUI for extracting OVL and OVS archives and modifying their contents, as well as editors for the associated in-house file formats. Also includes a model plugin for blender.
Get the latest source code here and unzip to a folder of your choice. You need to have installed:
- Python 3.7 x64 bit (make sure you add it to the system path during installation; 32 bit versions of python will hit their memory limit trying to read large OVLs)
- Microsoft Visual C++ Redistributable 2017 x64 (needed for texture conversion - you will likely have this installed already)
- Microsoft Visual C++ Redistributable 2013 x86 (needed for lua decompile - x86 version for now)
- pyqt5 (run:
pip install pyqt5in cmd) - imageio (run:
pip install imageioin cmd)
- Remember to backup all mod files and stock files. Any patches will reset or break the mods and will need to be redone and re-released.
- Not all model files are supported at this time. Some may crash on import or export. Even if they (seemingly) import and export fine, the result is not guaranteed to work ingame.
