Windows 10 1809+ or Windows 11 are now required due to the upgrade to Qt 6 and Python 3.11.

Unfortunately, MO2 cannot support Windows Store / Gamepass versions of supported games. The virtual filesystem is simply incompatible with the way the games are packaged.

For version 2.5.0, the installer will wipe any third party plugins as very few from 2.4.4 will be compatible with 2.5.0. If you've already installed a 2.5.0 beta build, I'd recommend simply overwriting the files using the archive download.

For older MO2 versions, a clean install is highly recommended if you do not use the installer as leftover files from 2.4.4 can and will break parts of 2.5.0 in addition to leaving old, extraneous files in the MO2 directory. You can migrate old portable instances by copying the mods, downloads, profiles, overwrite directories and modorganizer.ini file to the new install. If you use any third party game plugins, it is highly recommended to wait for an update before loading those instances.

Category Revamp

The default categories and Nexus category mappings are no longer hard-coded. When you create a new instance or load an older instance, you will be prompted to import and map the Nexus categories. You should be able to preserve your old categories if you had custom categories configured or use the old default mappings.

The updated category editor has a new interface to import the Nexus categories. These categories can be mapped to your custom Mod Organizer categories or imported. Importing the categories can replace or merge with your existing category setup.

In addition, you can automatically reassign categories based on your Nexus mappings using the right-click context menu or through the modlist dropdown action menu. For users updating from older versions, we can only map the category if you still have downloads with Nexus metadata available. As you install or update new mods, the Nexus category ID will be saved to the mod info as well. Mods without a valid mapping should be left untouched.

Finally, when you install a download from the download pane, missing mappings will trigger a prompt to update your Nexus mappings. You can also disable this feature entirely. This can be changed at any time from the Settings pane.

Python Plugin Updates

Python and Qt have both been updated to newer versions and Boost Python has been replaced with pybind11. These changes necessitate that most Python plugins be updated to be compatible with 2.5.0. On the other hand, you can now use Python 3.11.x features.

Basic Games

The basic games game support plugin system has had multiple updates to add and improve support for various game platforms, including EA Games, EPIC Games, and more. There are new utilities you can use to build more robust game plugin support with Python.

Game Support

Starfield

Starfield has full support with some general caveats. This includes save parsing, archive extraction and packing, plugin management, automatic archive invalidation, INI-enabled plugin and archive detection. This support virtualizes both the My Games Data directory and the game Data directory. This provides maximum mod support with minimal work needed by the end user. MO2 will create the Data directory in My Games, but due to the nature of the virtual filesystem, no files will actually we written to or read from this directory. This also allows SFSE plugins to be correctly loaded from the game Data directory.

Caveats

  • Plugin management is only possible by using the Plugins.txt Enabler mod. This can be loaded either with SFSE or an ASI loader. If you use the ASI loader you may want to disable this check. You must also remove any sTestFile entries from your game INI files.
  • BSA Packer currently does not support the newer Starfield archive formats and will pack files in the Fallout 4 BA2 format. This appears to work just fine and we will update to use the Starfield archive formats as soon as we can.
  • The BSA extractor has some trouble with archives containing numerous directories. Most archives are fine but you may experience extreme load times with the meshes / geometries base game archives due to them containing hundreds of thousands of individual directories.
  • Due to the nature of the game engine, only ESM files have relatively decent support and using another plugin type will generate warnings to describe the issues with using those plugins.
  • All Starfield diagnostic warnings can be disabled.
  • LOOT sorting is currently disabled by default as the LOOT team has decided that the issues with the engine make sorting too problematic. You can enable sorting in the Starfield settings. This could be useful if a future libloot / LOOT update allows sorting and can be hotfixed in MO2.

Known issues

Download Issues

  • There are still occasionally issues with index errors, we plan to resolve the remaining issues in 2.5.1

    • Often the download will still start regardless and this can be ignored
    • If not, usually just triggering the download again will continue normally

Other

  • There are a few graphical issues due to Qt 6, particularly when using themes
    • Some dialogs have strangely colored text which changes when you mouse over it
    • Some icons can be doubled with a slight offset
  • Archive files with a lot of directories can take a very long time to load for BSATK, this is typically only an issue for the Starfield meshes / geometries archives
