📋 About This Mod
but i don't have enough time to update it as much as I want
I'll leave this with all the old files and the repo in case someone want's to help out. For now I would recommend using Compatibility Framework for subclasses, they are doing an amazing work with it.
Mod Patcher Repo
Here's the new Project in case someone wants to check on the updates:
BG3CompatibilityPatcher RepoBG3 Compatibility Patcher is a Python-based application that dynamically generates a .pak file by merging Progressions.lsx from automatically selected mods, making them compatible.
Now with fully automated supported mod selection!
If a mod is not on the logs, the patcher skipped it.The main causes for this are:
1. The mod does not need a patch with your current load order.
2. It has an invalid Progressions.lsx (this doesn't mean it is not compatible.)
Requirements
None. Everything comes packed in the tool.
-
[]Dynamic Patching: Seamlessly merges Progressions.lsx files from multiple mods.
[
]Class/Subclass Support: Specifically engineered and tested for Subclass mods.[]Automatic One-Click Compatibility: Made so even grandma can use it.
No Installation Required
-
[]Run bg3patcher.exe.
[]Open BG3 Mod Manager and put the FFTCompatibilityPatch mod generated into your load order and save.

Always put the patch at the bottom of your load order.
The application automatically removes any temporary files upon closing to prevent bloating your temp folder. If you wish to keep the generated patch, make sure to move it to a different location before closing the app.
Icon Combination Feature
This tool has implemented an icon merging system that uses ImprovedUI Assets, injecting mods that aren't already compatible and makes them so. Ufortunatelly to make it work I had to make a decision: Remove the auto-packing feature because the lslib tool
-
[]Run bg3patcher.exe.
