CK3 to EU4 Converter

Description
CK3 To EU4 Converter

Welcome to the CK3 to EU4 Converter project! The goal of this project is to allow a Crusader Kings 3 campaign to be transferred and continued in Europa Universalis 4, so you may continue your game uninterrupted, from 867 to 1821+, and further using our other converters to Victoria 2 and Hearts of Iron 4.

Running a continuous campaign from CK3 all the way to HoI4 is called running a mega-campaign.

Converter is not a mod - it is a mod producing application
  • This converter currently supports EU4 1.30 and CK3 1.1. EU4 DLCs are optional, as are CK3 DLC.
  • This mod is not intended to be enabled in game. It is only a delivery vehicle for the converter's download link.
  • You can also download the converter directly from our forums thread[forum.paradoxplaza.com] or from Github.

Setting up the converter.
To set up the converter, you’ll need to follow the simple steps below:
  1. Subscribe to the this mod.
  2. If the mod does not immediately begin downloading, you may need to start CK3 launcher to trigger the download.
  3. Go to your mod folder (usually C:\Program Files (x86)\Steam\steamapps\workshop\content\1158310\2241203093, or elsewhere if you moved your steam library)
  4. Inside it find and open downloadLink.txt.
  5. Within that file are direct links to the converter's stable and development versions. Pick one and download it. Development versions are fresher and usually better.
  6. Unzip the downloaded converter by right-clicking on it and selecting Extract All…
  7. Finally, go to the extracted converter's directory and fire it up by running ConverterFrontend.exe.

If you downloaded the converter directly from forums or github, you only need to execute steps 6 and 7.

How does it work?
Every converter has a detailed documentation available at its wiki page[ck3.paradoxwikis.com].
Very generally, it takes your Crusader Kings 3 saved game and converts it into a Europa Universalis 4 mod.
You then have to enable that mod when starting EU4 launcher:

  1. Start the EU4 Launcher. Click Mods.
  2. Click Manage Mods.
  3. Click Initial playset and select Add new playset (or select the playset you're currently using).
  4. For a fresh playset, directly select the converted mod. Otherwise, on an existing playset in the bottom right corner click Add more mods and add it.

Troubleshooting and Suggestions

We are always open to suggestions on improving our converters and will gladly help you out if you hit a problem.

Best place for discussion on improving the converters are our Paradox forum release thread[forum.paradoxplaza.com] and development thread[forum.paradoxplaza.com].

When resolving issues we will always need if your conversion's log.txt. You can find it in your converter's folder after conversion. Come to the release thread linked above and upload your log.txt there, along with a detailed description of your problem. We may need additional data like your running savegame or mods used, which you can also upload to the forums directly.

Keep in mind Steam discussion below is not suited to troubleshooting as you cannot upload files we need.

@Projekt Neptunia: Wouldn't know, never played the game, sorry. Hopefully there are some mods that can do that.

"rack up revolt power and reduce domain limit."

Only that there is no rule in CK3 where you can set the revolt risk.

@GalakisDel8: Heh, you either convert closer to 1444 ot you just play the earlier bookmark. There's no good solution as EU4 doesn't support variable bookmark starts (so we could define two sets of dates and ages).
GalakisDel8 Nov 18 @ 1:14am 
How can I use the 1444 start date without everyone dying of old age immediately?
 [author] Nov 16 @ 4:16am 
Yes.
GalakisDel8 Nov 16 @ 1:25am 
Could it be because I am using the 1444 start date?
GalakisDel8 Nov 16 @ 1:23am 
When I convert to EU4 nobody has heirs and every ruler is 250-300 years old.I have no DLC other then Emperor

Just saw "Responsible blobbing", that's perfect ! Seems like a must for a megacampaign, i will definetely use it.
For now CK3 is too blobby, but i will try to emulate the diversity of a low centralized blob ( having 6 vassals eating diplo point seems a good penalty, as you will have to work around, free some, give estate privileges to manage that, and fight to keep the thing in one piece, delaying the blobbing...)
 [author] Nov 14 @ 2:17pm 
@Diskiant: There is precious little we can actually do with a blobsave. If we release more than a few vassals, you'll start with negative diploslots eating your diplo points. Best prevention is to reduce domain size in ck3 itself so people never get powerful enough to blob. In CK2 I told people: If you want a megacampaign, run with quarter demesne and halved vassals. Same applies here, rack up revolt power and reduce domain limit.

You can further mitigate this by using eu4 clamp mods. I wrote one (Responsible Blobbing) that punishes blobs hard, and there are many more you can use.
Diskiant Nov 14 @ 12:21pm 
Yeah it could be an option, blobing is a huge problem in both games for megacampaign. I'll study the code and what could be done and if i have an idea, i'll post on the developpement thread, but i understand that vassals management are not your priority at all ^^
Thank you for your time and for your work !
