CK2 Dev Diary#26: Considerable Converter Capabilities

Hello all, and welcome back to another CK2 Development Diary. If you didn’t notice last week, we now do CK DDs on Mondays to match up with the Medieval Monday stream. Anyway, getting on to the point of this DD: We’ve been updating the Converter!

Development in EU4 will now be based on the state of the world in CK2. Holdings, Buildings, Hospitals and Prosperity all count when determining if your capital should be the new Paris or not. The development of the default 1444 EU4 provinces (within the converted area) will be redistributed in a way that makes sense for your world.

Dynamic fort placement. No longer will forts be placed exactly as they were in the default 1444 setup, instead forts will be placed in strategically appropriate areas for each nation.

Revamped Tech Groups. Now, as Tech Group no longer actually affect your technology cost (that’s handled by institutions), your group will be based on the geographical area of your capital. This is then used to improve your experience in many ways, i.e. through custom idea generation!

Dynamic ideas. No longer will your nation simply have the ‘National Ideas’ set, instead a unique one will be generated for you based on your situation in EU4. These idea sets will give you appropriate ideas, so no naval ideas if you are landlocked or just have one port.

Institutions have been revamped to account for the vastly different world that is a converted game. The institutions will spread in a much more dynamic way, and no longer discriminates in favor of Europe (especially not if India or the Middle East manage to get a high Development converted over!). Institutions such as the Printing Press do not necessarily have to spawn in Germany, either.

Converter-centric idea picking for the AI. With most converted games missing a Portugal, and in some cases even a Castille or England, the AI has been readjusted to dynamically assume these positions. One nation will try to assume the role of Portugal - be it Iceland, Scotland, Korea or Majapahit you won’t know until you play!

Traits now convert over from CK2. Did you have a midas touched genius ruler or a possessed imbecile lunatic ruler? No matter what, you will recognize them by their traits in EU4.

Improved Sunset Invasion setup. For all of you who wanted the New world empires to be even mightier we’ve improved the High Americans with new missions and unique units. High American units tend to have many Fire pips, so beware their power!

The Converter will be updated alongside the release of Rights of Man on the 11th. That’s all for now, but I have even more Converter stuff to talk about next week.

That's what I get for having been a CK2 exclusive for so long: i keep thinking in those terms. Thankfully the code doesn't look at the values I think province have, but what they actually have, so it should be all right.
Just a note: Beijing should not be in the running, since we're only redistributing the provinces that have a CK2 equivalent.

Does it just look at total development and map province values directly over? If I have a large military province (mostly castles, lots of troops etc.) is it more likely to give a lot of base manpower or is it just going to say high development - you get X province's stats (when X province has high tax and production but poor manpower)?
 
Sorry if it was brought up before; is there a way to show information on reason of imprisonment? After many years I often find my dungeon full of strangers, some of them were obviously children when incarcerated following a siege; some were plotting a murder; some were just at the wrong place at the wrong time, like being caught having sex with a courtier and some are just there for pleasure. It's so difficult to keep track with current UI.

So, theoretically, if you have an Ireland with all maxed out provinces in CKII, you could have an Ireland in EU4 with all their provinces around 30-32 Development?

Also, how does the tech level in CKII convert over to EU4?

Will the converter convert Castles, Churches, and Cities into different types of development?

We want converted games to be more open and 'fair', so there's no way to force it. You can easily mod it though.
They will pick early Exploration ideas, so unless they're crushed by war they should explore & colonize early on.

Wouldn't it make the most sense to only allow developed coastal powers closer to the Americas get this ability?

So, essentially Japan, Korea, Ming? Rather than folks in India far away?

Or would an Indian 'Portugal' colonize Australia instead?

well Portagal also did a lot of colonizing/conquering in Africa, though those trade nodes wouldn't be of much use to an Indian nation without changing how trade worked. I really wish it was possible to make trade flow "backwards" if you(or you and enough other "upstream" nations) had enough control in the "downstream" node(s).

Well, the trade routes depict the actual historical flow of goods.

What they need to model is a supply/demand system that benefits starting nodes with Development discounts, tax boosts, and the like.

This is exactly it. We sort all EU4 provinces by their development, then sort all CK2 provinces by their pseudo-development (the mentioned value), and we give each CK2 province the develoment of the province of the same rank in EU4.
So if say Kernev was a megalopolis with all 7 settlements filled to brink, plus an hospital also filled to the brink, a trade post and prosperity 3, Kernev in EU4 would receive the development of Constantinople (or Paris).
This way the map stays balanced, but the most developed area of CK2 are also the most developed areas of the converted game.


A lot of the converter can be modded, it is one of the way we encourage people to improve the conversion to fit more with their vision of what it should be.
To answer the specific question, the personality trait conversion can be modded to add more or remove those you don't like.


We have found the issue, and a branch should be available.

@Moah, this might be last minute to implement immediately, but can you please add an element of change to East Asia depending on the state of Western Society?

Ming formed as a result of the fall of the Yuan dynasty, which was itself a Mongol Dynasty that only existed after the fall of the Tang, the rise of the Song, the decline of the Song and the rise of the Jin, and the fall of the Song and the Jin to the Mongol Yuan Dynasty.

All this happened during the CKII era.

If the Mongols don't spawn, or are driven back from the west in defeat, the Yuan would never overrun the Song.

Can we please have a more varied China, Korea, and Jurchen in conversion?

Butterfly theory, @Moah, butterfly theory. @rageair, what do you think?

@Trin Tragula, @Darkrenown, @Doomdark???

another question about the converter: will large Muslim nations no longer be broken up into clusters of PUs and just have vassals? after all Personal Unions aren't available to non-Christians in the game.

and on the subject of Persnal Unions, will there be a possibility that large nations where the ruler has multiple titles of the same rank have his realm broken into PUs(especially if crown authority is low/council power is high)? or will that have to be something reserved for manual editing?

It's a cool idea, but it's outside the scope of this converter update. It's really outside of the scope of the converter itself since it doesn't really touch Asia.

If it isn't a bother can you say what was the issue? Curious about what was making such a huge difference.

Turned out to be a code thing, some MP things were being checked in SP and wasting a lot of time.

How bout a nice 0/0/0 instead?

I don't remember if it's 1.18 or RoM adding it, but you could always abdicate ;)

To be fair, so is america and that doesn't stop sunset invasion from making the new world into a completely different environment.

What CKII version will the converter be compatible with? Do I have to restart my current game in the current version if I want it converted?
Almost certainly 2.6.2. Anyway you most likely will be able to load up your save in 2.6.2 and then convert instantly unless you are using a version before the last map change. (Not sure when that was; has there been changes since Horse Lords?)

My problem in that I didn't patch up with conclave so, it hopefully not breaking the save, would need to go to the command console command that allows the auto change of all laws. Then, I would need to go through every realm. Still, it would be worth it.

Why would you need to change laws through console?

And as mentioned you should be able to load a 2.4 game and then convert instantly. If you try to actually unpause you might get in trouble, but just converting without unpausing ought to work. (I know that 2.4. saves at least could be converted with the 2.5 converter, since I did that.)

I’m working on modding the Converter for the HIP mod project. I have some questions which don’t seem to be answered anywhere and I’m hoping since this is being updated, I could get an answer to any of them. I recently reported a Converter crash, with fix, for y'all so can I parley that into some aid here? :D
  1. How nation_table.csv works – it doesn't seem to always convert CK2 realms to their mapped EU4 tags. Does order matter – will it prefer to match k_castilla rather than d_castilla just because the former mapping comes first in the file?
    1. What do the entries do at the bottom of the file, with blank CK2-title entries? They say “exists in EU4, not in CK2,” but that’s true of lots of tags not listed.
  2. Generally how province_table.csv works – how does it handle many-to-one, one-to-many, and many-to-many relationships between CK2 and EU4?
    1. E.g.… if 3 CK2 counties are mapped to one EU4 province, and A controls two of them while B controls the third, does A always get the province in the conversion? Does that depend on the order the mappings are listed in? If the third mapping were tripled, would that mean B now gets the province?
    2. Whether the third column "Filename" of province_table.csv matters at all—given that about 15% of the entries in that column don't point to actual province history files?
    3. What is the sense in having duchy titles in that table (as it has in at least some places)? Why would they matter for province mapping?
    4. There are some lines duplicated, with a comment saying it’s to increase the weight of a certain option. How does this work? To what extent is it deterministic vs random?
  3. What’s the point of border_provinces.csv? Especially since the map has expanded to the east since that file was changed?
 
Beijing: 33
Paris: 32
Milan: 30
Rome: 28
Constantinople: 23
London: 22

Moah probably meant post-event Constantinople.

I keep forgetting that London was nerfed following the change to development as my only game that involved conquest up there ended early due to my third 13 year regency within a century made me rage quit. Thanks for the data!

That's what I get for having been a CK2 exclusive for so long: i keep thinking in those terms. Thankfully the code doesn't look at the values I think province have, but what they actually have, so it should be all right.
Just a note: Beijing should not be in the running, since we're only redistributing the provinces that have a CK2 equivalent.

Will there be some meshing of development values between the untouched east Asian provinces and the rest of the map? Seems like things could get jarring without it.
