CK2 to EU4 Converter Release Thread

[Zemurin]

Over the course of past few weeks we have created an alternative CK2 to EU4 converter. It's been hugely fun and enjoyable experience, and now we proudly present to you the result.

How conversion works - see the details:

Map conversion

• We try to alter the map as little as possible against vanilla. If a country's not in scope of CK2, it is untouched. This applies to county histories as well - so this means most countries will not have a history (monarchs, leaders, advisors) identical to EU4 if you convert before 1444.11.11
• For those countries in scope of CK2, we tread lightly, only updating necessary elements, like which provinces are owned and which not. We try to be very careful there as well, resolving collisions by looking at which ruler developed their land the most, or has maybe built a great wonder there.
• All of the provinces in CK2 have been painstakingly remapped against 1.29 map, and if we missed a spot please tell us.

Religions and cultures

• The religions have been expanded, and EU4 conversion will support most of CK2 religions. These religions are also compatible with EU4toVic2 converter.
• Cultures have been expanded greatly, and we do not import CK2 cultures on 1:1 basis - instead we split them up. Italian can break into Tuscan, Lombardian, Umbrian, Venerian and so on, as we try to emulate EU4 style of cultural groups.

Advisors, Rulers, Queens and Heirs

• You'll find councilmen you had in CK2 available for hire in EU4.
• Rulers are converted ad-verbatim. If a ruler is too young to rule, a regency council will be set up for them.
• Queens (or Prince-consorts) are also imported where possible, to help you stabilize the realm at start.
• Heirs are imported where possible. Since we do not have access to memory-state of a running CK2 game, we had to make educated guesses for some of the more obscure succession choices, so do not mind a lack of heir that sometimes can happen.

Diplomacy, Vassals and Personal unions

• For a christian ruler that holds multiple crowns (of same level), he will find his realm split into multiple states, under a personal union lead by him.
• Non-christian rulers in the same situation will simply absorb the other crowns.
• Large vassals, holding inappropriate amounts of provinces (compared to the total country size) will be split off into vassals at conversion.
• Royal marriages are not imported, and neither are alliances. Unlike CK2, in EU4 diplo slots are few and with some of them already taken by vassals and PUs, we did not want to choke the player.
• Tributaries are also not imported at this stage.

Buildings, Development and Wonders

• We do not import any buildings. Only building that is supported at game start is the humble Fort.
• Small countries (but not OPMs or similar) will only receive a capital fort, while larger ones will receive a fort in every state or territory they mostly control.
• Unlike buildings, development does map directly against CK2 development. the more castles one has in a province, and more buildings inside each, more manpower is received. Similar to cities and production, and finally to temples and tax development.
• Wonders are imported in the same fashion as the official converter does- as permanent province modifiers granting powerful bonuses.

HRE and Empire Shattering

• Entirely player's choice, the HRE can be kept as an unified country or shattered in EU4-style microstates. If shattering is enabled (which is recommended), the converter will carefully choose which tags are to be turned into free cities and electors.
• Which empire is to be the new HRE is also up to the player - you can HRE-ify Byzantium, Rome, or any empire you choose.
• Empires all over the map can be shattered into smaller independent kingdoms, in case your CK2 game was too blobby.

And that's all for the first release. More to come as we fix more bugs, work on more cultures etc.

[Zemurin]

Barcelona Release brings several new major expansions, fixes and features.

Conversion Features

Bookmarks

• Converter now offers two bookmarks - a fixed 1444 start, and a floating bookmark at the date of conversion.
• The floating bookmark is the canonical one and all rulers, heirs, and game world is transferred directly from CK2.
• Floating bookmark will have technology frozen (same as CK2 in its entirety has technology basically frozen), until 1453 when regular tech advancing starts.
• 1444 bookmark will have some oddities like 500 year old rulers (for a 500 year skip, but aside for this issue (which will resolve itself within months after game start) is perfectly usable.

Mod Support

• Since CK2 save games carry no information about mods used, we have introduced the Rummage system.
• Converter will rummage, uninvited and unbidden, through all the mods installed in CK2 mod folder, and look for definitions to those variables it lacks. For example, using a mod that introduces new dynasties is now possible.
• Where the converter fails to find such data, it will still default to reasonable educated guesses and no conversion is likely to look like Swiss cheese.

Ruler Bling

• Prestige is now transferred in a scaled fashion - prestigious rulers will have their countries start closer to 100 prestige, while virtual unknowns will have their countries start at a large penaltiy.
• Money is transferred in a similar fashion (and only for positive coffers), but do not expect more than some 100-200 ducats even if you held a million in CK2. Time passes, and prices inflate.
• Being in debt to Jewish moneylenders will in fact transfer as a starting loan - while not large by any means, it will have a significant interest rate.
• Excommunicated rulers from CK2, transfer as such into EU4 - this applies, naturally - only to Catholic and Fraticelli rulers.
• Monarch history is now imported and monarch now receive proper regnal numbers - so John III would remain so after conversion, and his heir, if named John, will become John IV on succession.

Claims

• De Jure territory now transfers as permanent claims.
• For example, a ruler of e_scandinavia will start wit permanent claims on all unowned territory that was mapped from CK2's e_scandinavian provinces (even if these claims extend into Russia or elsewhere through de-jure drift.

Tributaries

• Converter will now transfer all tributaries, ad-verbatim, to EU4.
• This means even christian countries can start with some tributaries in tow.

China

• China is now dynamically assigned to an appropriate chinese dynasty tag. For example, if Han control China, MNG is replaced with HND.
• Celestial Emperor has his dynasty, religion and culture preserved.
• Western Protectorate is integrated into China mainland.
• Western Protectorate's tributaries are transferred to China, in addition of preserving all historical tributaries from vanilla 1444 start at both bookmarks.

Fixes and Changes

Countries, Names and Flags

• Countries will now start with their custom names they held in CK2. If k_lithuania was created by a Prussian (pruthenian) duke, and had name swapped to Prussia, it will now remain Prussia (although still having LIT tag)
• All muslim kindgoms and empires will be named after their ruler's dynasty. This will not affect their tag, ideas or missions.
• All muslim countries can now use custom flags representative of their ruling dynasty. We have created flags for a dozen dynasties, and more will come in future.
• Many new countries have proper tags - most notably the entire plethora of holy orders (for all religions)

Provinces

• Province mapping algorithm has a glaring flaw that allowed some vanilla EU4 provinces to bleed through, along with their countries. The hole has now been plugged.

Cultures and Religions
Note: All of these changes are supported through EU4 over Vic2 to HoI4.

• Jewish cultures have been broken down akin to all other major culture groups.
• Roman culture suffers the same fate.
• Qarmatian is now a recognized religion.
• Personal Deities were assigned to Khurmazta (with accompanying new graphics).
• Fetishist religion has been updated significantly, receiving new cults due to new religions.
• With new religions in tow many decisions have been fixed to include these (Prussia can be now formed by Waldenesians).

Aside for these, many minor under-the-hood fixes and patches were implemented, as always.

​

FOR CK2 [3.3] AND EU4 [1.30]​

We've been holding on for 1.30 release, so the list of updates grew quite large. Here are the most important ones:

Conversion Features and Fixes
Sunset

• Sunset can now be toggled as an option during conversion.
• Sunset has been reworked from ground up. High Americans have an already reformed religion, will be able to build ships, and will most certainly be able to spawn institutions. Expect them to be quite a challenge, unless Incas and Mayans die in mutual clashes, seeing how they are historical rivals (and they have no one else to rival anyway).

Shattering

• You can now provide a targeted list of empires to be shattered in shatter_empires.txt and enable it in the converter options. This is highly advised in case your CK2 game ended in a bunch of megablobs.

Country Names

• Instead of tying dynasty names for countries to religion, we've remapped it to use cultures instead, with a handful of exceptions. In case of a Christian Turkish Capet ruler of Persia (actual example from saves), expect to see "Capet" nation, with probably a few "Capet Arabia" or "Capet Egypt" countries as PUs.
• When several countries shared the same name (d_bohemia separate from k_bohemia), we now generate new names to differentiate them - Greater Bohemia, Lesser Bohemia, etc. Up to 5 variations for the same name are supported.

Cultures

• Cultures have been painstakingly checked and tweaked. Specifically German and Italian culture are better differentiated outside their home regions. Rome will remain Umbrian.
• Turkish and other asian cultures have received tweaks and differentiation.
• Roman culture will now correctly break apart across the continent (and outside of Europe).
• Tartars, Jews, Africans, cultures all across the board have been polished.
• Wrongly mapped ex-burman cultures have been correctly moved into tibetan group.

Religions

• All religions have reformed and unreformed variants.
• Unreformed pagans can reform by taking a decision once they control all 5 Holy Sites, even in EU4 timeline.
• Tengri from far east (outside CK2 scope) will unreform, regardless of the state of Tengri in CK2 scope.
• The bug with countries and rulers defaulting to their historical dynasty religion has been corrected.
• Buddhism (Theravada) has been split into Theravada and Vajrayana along geopolitical lines.

HRE Electorate

• Instead of choosing electors at random, converter will now attempt to assign electorate seats to CK2 electors, if at all possible.
• Bug where free cities could become electors has been fixed.

Government Reforms

• A large amount of effort has been invested so that countries, according to their laws, rulers, geographical position, culture, religion and features, would start with an appropriate starting government reform. However, these reforms do not include the new ones introduced with 1.30 patch.

Development

• Converter now offers an option to retain EU4 vanilla development, which is quite necessary for very early conversions where entire world will otherwise be a swamp.
• Development has been eased from 12 to 10 buildings per dev point. Baronies themselves are still worth 0.3 dev each.

Provinces

• We missed a few of the provinces introduced post Holy Fury and have now mapped all CK2 3.3 and EU4 1.30 provinces.

Dead Cores

• We now distribute dead cores of primary cultural nations, unless those exist as extant countries. For example, if Scandinavia eats France, you can expect to see French cores in french provinces, so the country may be released during EU4 timeframe.

Siberia and Africa

• Converter will no longer purge those Siberian tribes with more than 5 provinces as they are no longer insignificant.
• Saharan passes are now sterilized to separate african primitives from predatory countries of northern africa. This gives them time to develop and prevents immediate blobbing into subsaharan africa.
• Passes will not be cleared if a nation already holds both ends of a pass.

Frontend

• The old Frontend program has been replaced with a brand new one, called Fronter, which does everything the old one did as well as display conversion progress. Yay, a technological leap! Backwards! From C# to C++!

Aside for these, many minor under-the-hood fixes and patches were implemented, as always.

NEW VERSION NOW RELEASED!
(DIRECT LINK TO THE DOWNLOAD)​

FOR CK2 [3.3] AND EU4 [1.30]

This release is dedicated to three special snowflakes, each more exceptional than others. These are the Pope, the Fapope and the HREmperor.
In addition an imperial ton (metric not invented yet) of fixes and patches has been applied.

Conversion Features and Changes
Culture differentiation

• Better generation of Italians, Slovaks, Slovenes, Greeks, Bretons.

Ages, Ideas and Institutions

• Ages, ideas and institutions have been fully patched to 1.30.
• Special age abilities have been divorced from named tags and opened to anyone with appropriate culture/religion background.

Countries, Reforms, Decisions, Estates

• Holy Orders have been patched to work better.
• New 1.30 government reforms have been fully integrated and available to nations fulfilling their requirements.
• Targeted government reforms now work again.
• Qing can now adopt Manchu culture.
• Dead nations no longer get to have permaclaims on DeJure provinces.
• Updated formable decisions have been patched to work alongside their vanilla counterparts, difference being they allow a wider range of religions/cultures/other conditions where applicable.
• Some estate interactions have been fixed to allow wider use.

Map fixes

• Arabia, Balkans, Tartary, India, Greece, Urals have revised mappings.
• When multiple provinces vie for an EU4 mapping, they now correctly do Battle Royale with their development, wonders, capital statuses and similar.

Development

• Development from baronies (0.3) and individual buildings (0.1) can now be manually tweaked in dev_weights.txt so that users can adjust total world development to their liking.

Optional Vassal splitoff

• Splitting off major/influential vassals into autonomous countries can now be disabled in configuration, though we recommend leaving it enabled.

The Snowflakes
Pope and Fapope

• Popes now directly assimilate all land they own, bet it France, Jerusalem or Romagna.
• Assimilated countries under pope do not leave cores behind, but national/cultural cores are still generated as usual.
• Popes have a priority as electors if in HRE.
• All Papal/catholic decisions/mechanics now have Fapope/Fraticelli counterparts with slightly different effects. Fapope will be better at preventing reformation.
• Papal names and localizations have special overrides and mechanics.

HREmperor / HRE

• HREmperor's capital is the single most important province in the world and will always belong to him.
• After deleting e_hre and probably HREmperor's kingdom, his primary duchy will be set to the one containing his capital.
• If he holds no duchy over his capital, his capital county becomes primary and will be able to PU/annex other owned counties/duchies.
• Baronies no longer qualify for becoming the HREmperor.
• All Dejure HRE land held by others will now be marked as such in EU4.
• Electorates are no longer giver to junior PU members; when distributing PUs, the tag flagged as emperor/elector will automatically become senior.
• Free city generation is now fixed to exclude juniors in PUs, electors and similar.

Fronter

• Instead of relying on all mods present on the system, the Fronter has now been expanded with mod detection so the user can pick those mods that were actually used in the game.
• Fronter now also allows users to use spaces in custom output mod name, which previously didn't work.
• Instead of relying on common-sense directory paths, Fronter will now prevent usage of paths that "don't exist" (notably when OneDrive symlink folders get in the way). Previously this produced a hotbed of confusion for users.

Aside for these, many minor under-the-hood fixes and patches were implemented, as always.
