Larian Studios Forums Divinity: Original Sin 2 - The Modding Dungeon Divinity - Original Sin 2 - Modding Guides [Guide] Making Your Mod Achievement-Friendly

â–  While a majority of your mod files need to be moved from Public/MyModName_GUID to Public/Shared. Some files need to remain in the original directory. More on this below.

â–  Assets need to be in their original paths that were set in the editor. Meaning, if your path to a texture file was Public/ModName_GUID/Assets/Textures/, that path needs to be preserved. So keep that in the same folder structure.

â–  Your texture atlas files (i.e. Public/MyModName_GUID/GUI/MyMod_Icons.lsx) need to be moved into the Public/Shared folder.

â–  Localization files need to be renamed to not override the base ones (Shout_DisplayName -> MyMod_Shout_DisplayName). Any localization files in Mods/MyModName_GUI/Localization need to be moved to the "Public/Shared/Localization folder".

â–  All your new StatusData entries need to be merged into the base game's StatusData.txt. Get this by extracting it from Shared.pak.

â–  For your other stats, simply renaming them appears to be fine (Potions.txt -> MyMod_Potions.txt).

â–  The rule of thumb is to be aware of what you're overwriting, and if it actually needs to be overwritten. In most cases, a simple rename may work, unless it's an integral file that the game only loads once (StatusData.txt, Data.txt).

â–  Mods/MyModName_GUID/meta.lsx does not need to be moved to Mods/Shared. Doing so will actually prevent the game from opening.

A general thing to note is that packing files this way overwrites the WHOLE file, whereas modding the standard way will only overwrite specific entries. For example, a packed mod may have a Data.txt file that only has the 4-5 parameters it modfiies, but the loose version needs the whole Data.txt file with the modified parameters integrated in it.

I assume this would only work for mods that don't touch the story editor, correct

It would probably be easier to figure out a way to patch out whatever's disabling the achievements, like they did for Skyrim.

My guess is there's a check in the engine for specific information in the meta data of the main game and if something is sitting on top of it cheevos are disabled.

unless Larian changes it in the coming months.
