Sorry for not responding sooner. We really didn't do any serious work on this converter to make vanilla great works compatible with anything custom in particular. But from what I gather your great works are imported ones? I don't think we put any specific limits on cultures or religions for imported stuff.

In any case, easiest fix is to edit them manually and drop all requirements. I don't plan to do fixing for this as this converter is on maintenance only.
No worries, I appreciate you taking the time to answer!
 
"Where secesful" isn't a word.

The converter finished. It had a ton of errors because you used a cocktail of mods which are not supported by the converter. As usual. You keep using mods that change entire game and none of those are stuff we support.

I installed the converter on Linux using the version currently on git and the .mod files it created had two version of the path variable. One was mod/[name] and the other was /whole/path/to/mod/[name]. The EU4 launcher did not like this! I replaced the initial path variables with the more complete path variables and removed the duplicate path variables (so the only path was path=/path/to/mod/[name]) and it seems to be working now.

Edit: On another note, it's strange that the Roman Empire is assigned Autocracy by the converter by default instead of the Roman Empire government reform. That can be easily changed on my end, though.
 
CK2>EU4 Question:
Is it possible, after the converter has created the mod file, to edit the mod to where it only uses the data for one specific nation (ie: the one you played in CK2)?

Basically, I want to play through CK2 with my nation/dynasty, but when I import it to EU4, to have my nation be the only one changed but the rest of the map reflect the 1444 EU4 start.

I have some experience modding in this engine so I'm sure I can figure it out; I just wanted to ask before looking into it if it was possible. (Or if I would be better served just doing an uncapped custom nation in vanilla EU4.)

You could, technically speaking, painstakingly delete all historical data for every province not owned by you and so on but with custom religions, cultures and whatnot (especially foreign cores!), there's too much intermixing for this to be easily doable.

It's much easier to just start vanilla EU4 and create a custom nation with your custom dynasty and whatever ideas you see fit. There are mods that remove point limits in the custom nation designer so you can make it as large as needed.

Hello, with the official announcement of eu5 i was wondering if there were any plans to develop a ck2 to eu5 convertor? i feel as though ck2 does a much better job simulating this era in history compared to ck3.

There is a plan, yes. How it goes or who will be fronting the effort will remain to be seen.

Hello!

I was notified I should make a bug report here instead of the Github, so here I am.

I'm noticing an issue with some of the files for cultures that split into various sub cultures, specifically noticed this for Mongol and German cultures, but IDK if it's an issue for any similarly splitting culture. No matter where they are, the heirs and wives of the Mongols automatically become Astrakhani, whereas the Germans become Alsatian. I have an example history files attached, one for Germans and the other for Mongols. Let me know if you need any other files to help!

Please upload your ck2 save and conversion's log.txt. You can find it in the converter folder after conversion.
 
Hey there! I'm using the converter on a CK2 save on the latest version, vanilla, no mods with all DLC enabled. It sent out this error log on a CK2 save that ended in 1456.

Thank you for the report. I have pushed a fix for this issue. Please update the converter and retry.
 
I noticed the province mappings on the Anatolia border are not very good. Obvious corrections should map CK2 Aintab to EU4 Ayntab (ck2 = 734 to eu4 = 4298), CK2 Edessa to EU4 Urfa (ck2 = 699 to eu4 = 2308), CK2 Tao to EU4 Tao (ck2 = 680 to eu4 = 4303), CK2 Theodosiopolis to EU4 Theodosiopolis (ck2 = 704 to eu4 = 331). Its probably worth it to review the whole region.

Jesus man, those mappings haven't been touched in over 5 years. They were atrocious. I redid entire anatolia up to persia, and upwards to caucases. Update the converter and retry.

Its a bit better. Thanks.

However, now you don't have Mosul mapping to Mosul and Irbil mapping to Arbil.

Its also may be worth noting that modern Diyarbakır historically replaced Amida. So Amida should probably map to Diyarbakır

Also Ani should probably map to Kars. The Turkish name of Ani is Kars in CK2

After looking through the Turkish and Greek translations in CK2 and EU4, if we take this as a clue for mapping provinces, this is how they should be mapped:

CK2 682 (translated in Turkish to Van) to EU4 2307 (Van)
CK2 672 (translated in Turkish to Erivan) to EU4 419 (translated in Turkish to Erivan)
CK2 681 (translated in Turkish to Kars) to EU4 2204 (Kars)
CK2 703 (translated in Turkish to Erzurum) to EU4 331 (Erzurum)
CK2 683 (Amida) to EU4 418 (translated in Greek to Amida)
CK2 680 (Tao) to EU4 4303 (translated in Georgian to Tao)

Other corrections:
CK2 697 (Mosul) to EU4 411 (Mosul)
CK2 685 (Irbil) to EU4 4293 (Arbil)

The problem with mappings in general is we try to stick to geographical matches as close as we can. Mapping city X from one game to another can be done directly but if we do that exclusively then we break a lot of mappings around those specific provinces. And provinces with the same name differ a lot geographically across the games, and often aren't even in the same spot at all.

So, it's about balance. If you want to change stuff, go right ahead, but I'm pretty ok with current anatolia and middle east as it is right now.

But hey, you can use the provincemapper and try to do a better job, I don't have an issue merging contributor fixes, on the contrary.

I know it may not be perfect. But you must admit Mosul not mapping to Mosul is a little egregious don't you think?

I will also post an updated file here once I am done looking through it.

Update: I have attached the fixes. If you decide you don't want to apply them, I will not be offended.
