This converter will allow you to take a game from the end of CK3 and convert it into a playable EU4 save, continuing your game. It will be compatible with the EU4 to Vic2 and Vic2 to HoI4 converters, allowing the player to play a continuous megacampaign from CK3 through HoI4. This project is a successor of the CK2 to EU4 converter project.

Features

Requirements

• Crusader Kings III with optional expansions, latest version is required.
• Europa Universalis IV, with optional expansions, latest version is required.

Incoming Savegames

• Converter supports compressed save games.
• Ironman saves are supported.

Outgoing Mod

• Converter will produce an EU4 mod.
• Using the front-end, the mod will be copied to EU4 mod directory, located in the user's documents, usually C:\Users\User\Documents\Paradox Interactive\Europa Universalis IV\mod.
• Without front-end (running the converter manually), the mod will be exported to the converter's output folder, and will have to be moved manually by the user.

Bookmarks

• The converter ideally supports two starting bookmarks - 1444.11.11 and the date at conversion. Players starting earlier will have to wait for 1453 to begin with regular tech progression as technology during CK2 era does not change much.
• Starting before 1066 will require the player to embrace Feudalism institution as it canonically starts at 1066.

Map conversion

• Converter tries to alter the map as little as possible against vanilla. If a land is out of CK3's scope, it is left untouched. This applies to country histories as well - most out-ot-scope countries will have a history (monarchs, leaders, advisors) identical to EU4 if they start at 1444.11.11 bookmark
• For those countries inside CK3's scope, the conversion treads lightly, only updating necessary elements, e.g. which provinces are owned and which not. Further details on how this is done will be added.

Religions and Cultures

• The religions have been expanded, and EU4 conversion will support mappings for all CK3 faiths, although sometimes merging them with other religions. These religions are also compatible with EU4toVic2 and Vic2ToHoI4 converters.
• All CK3 religions have both reformed and unreformed variants, and it is possible for a surviving unreformed country to reform their religion within EU4 timeframe.
• Cultures have been expanded greatly, and CK3 cultures are not imported on 1:1 basis - instead they are split up. Italian can break into Tuscan, Lombardian, Umbrian, Venerian and so on, as the converter tries to emulate EU4 style of cultural groups.
• Countries can be named after their Dynasties (though they retain canonical tags and have canonical missions and ideas), and some of these dynasties have custom flags. This applies to countries with cultures that support such a renaming.

Buildings, Development and Wonders

HRE and Empire Shattering

Frequently Asked Questions

Q: Is this the official converter?
A: This converter has been done by the same team that specializes in other Paradox converters: CK2->EU4, EU4->Vic2, Vic2->HoI4, CK2->EU3, EU3->Vic2, Vic2->HoI3, and relatively soon, Imperator->CK3 It is not official, but the team is experienced.

Q: I have an ironman save. Can it be converted?
A: Yes.

Q: What about mods?
A: Unless they change how cultures, religions or flags work, sure, use mods. Total map overhauls are not supported (of course), and whatever new cultures and religions are brought by the mod - you'll have to add manually in the files in configurables folder.

Q: How can I customize my game after converting?
A: Use the guide in after_converting.txt in the converter subdirectory. Scan through configurables/ folder and look into the myriad of configuration files - a great majority of these files is intended to be modified by users to achieve specific conversion results.

Quick Troubleshooting

Q: When starting conversion, conversion immediately ends, not producing anything.
A: Inside the converter folder there is a file called VC_redist.x64.exe. This is Microsoft's C++ redistributable package the converter relies on. Install it and re-run the conversion.

Q: The generated mod was in a different language than my savegame.
A: At the moment, CK3ToEU4 only guarantees English localisation, but German, French and Spanish are nominally supported.

Q: Some/all country names appear as X25, FRA etc.
A: This is an issue with the localisation. Only English is guaranteed, and you may be running EU4 in some other localization. Also, CK3 often lacks named and adjectives for various titles in non-English languages. We try to use English localisation when this happens.

Q: I loaded my mod, but nothing changed. What's wrong?
A: Is the mod enabled in the launcher? If so, then EU4 refused to load it due to possible errors. Respond to the forum thread and upload your save, log.txt and errors.txt so we may debug.

Q: The country crashes upon selecting a country and pressing play (at map selection)
A: Upload your save, log.txt and errors.txt to the forum thread for further study.

Q: The game forbids me to select nations.
A: Upload your save, log.txt and errors.txt to the forum thread for further study.
