HOI4 Modding Your Own World 

it is 1.9.3 and this doenst seem to work anymore, ive followed all the steps of this tutorial but it doenst even crash my game, my map just isnt ingame

Baumus mine randomly crashes around the “loading checksum” thing

Thank you very much i am in 1.10.1 and it works !!!!!!!!

@@baumus8278 i did it on 1.10.7 so you must have done something wrong. In fact i am sitting in front of my "Mega state". Now i am working on the 2869 States in my world :D

@@wh965 yeah no ive got it to work, i thought that apart from the tutorial it would be everyhting i would need to do, turns out map modding is a huge fucking headache

hello, wanna create a mod with me, i got big ambitions

@@mistarnoob1495 interesting, explain them

@TranscaucasusMapping kek, maybe

you absolute chad this is so helpful

no snow?

Luigi Aparelli i made one! :p

Gacha Plam beautiful ❤️

So how do assign it?

Lmao zedong hey! There’s an easy way to do this, there’s a mod I use called easy buff, it adds another row of slots with different things in them, the mod is used for cheats but you can copy and paste and edit them easily. I can make a video soon I’ve just been very busy as thanksgiving week is when teachers love to cram in a lot of projects and tests.

@@rebelsj2159 Thanks!

@@rebelsj2159 Also, I have another question. How would you be able to edit the map via specific terrain? I'm not familiar with paint.net. And how would you create impassable regions?

Mao Zedong hey, to edit terrain, use nudger, in database tab there should be a section where you can paint provinces, and to make a state impassable simple add “impassable = yes” in any state you want to be impassable

@@rebelsj2159 Thanks again!

i know this comment is 5 months old but heres a few ways to fix that method #1. Right click on HOI4 in your steam library and open properties. Click on Set Launch Options and enter -debug then press enter. method #2. Open the base HOI4 game files along with your mod files, copy every country from the base game's common/countries file path into your mod's common/country file path. method #3. Open the base HOI4 game files along with your mod files, copy the generic.txt file from the base game's common/national_focus file path into your mod's common/national_focus file path. method #4. Install notepad++ or use any other text editor other than Notepad. Go to Documents\Paradox Interactive\Hearts of Iron IV\mod and right click on the .mod folder created for your mod. Paste this at the bottom of the code for it: replace_path="common/ai_peace" replace_path="common/ai_strategy" replace_path="common/ai_strategy_plans" replace_path="common/ai_equipment" replace_path="common/bookmarks" replace_path="common/decisions" replace_path="common/decisions/categories" #replace_path="common/technologies" #replace_path="common/autonomous_states" replace_path="common/ideas" replace_path="common/national_focus" replace_path="common/on_actions" replace_path="common/scripted_effects" replace_path="common/scripted_localisation" #replace_path="common/scripted_triggers" replace_path="common/units/names_divisions" replace_path="common/units/names_ships" replace_path="history/countries" replace_path="history/states" replace_path="map/strategicregions" replace_path="map/supplyareas" #replace_path="music" replace_path="events" replace_path="portraits" replace_path="country_leader"

clxne I got no errors and it still crashes. What now

​@@thezombiecreeper For me, for some reason, adding the 'generic' national focus tree in 'common/national_focus' fixed it. I also got no error, and that was the only thing i changed.

@@clxne8312 Thank you it worked for me.

Jonnymur sorry for the super late response, I haven’t seen this before, any major errors in the error log about maps or definition file?

nudge tool is a bitch

wut

Hi, that’s very strange, is it possible that you can send me your mod files on discord and I can look at them as im unsure why that’s happening. My discord is Rebelsj21#4351

@@rebelsj2159 Hello, sorry for the late reply, I managed to find the problem, turned out that i was missing a province id in the definitions file and since the provinces weren't in the correct order it kept crashing. Thank though

koola saurus ah ok. Glad to hear it’s working.

@@rebelsj2159 Hello. When I launch the game, it loads properly. But when I start playing for the country I created, there is a crash. The log also only has "map / weatherpositions.txt is empty.". Can you help me?

Jaden Lawrence sorry for the super delayed response, yes that file should have generated with the MapGen when you made the mod. If you dont have it I recommend regenerating your map as that file is necessary

​@@rebelsj2159i regenerated the map but its still doesnt give me the map file

Dm Inc. you got it to not crash while loading? How?

idk how honestly i just did something i guess. i dont know anything about modding. also, the issue wasnt solved sry. i really dont remember what i did tho

Dm Inc. ah ok

If there’s sea provinces it should work, also make sure you do buildings in the nudger, if the port looks like it’s in the middle of the province use the building tab in nudger cause it won’t work then

Oh I didn’t know that’s what boundary input was but I know what ur talking about now thank u

@@rebelsj2159 EDIT TL:DR edition: I actually tried long ago and it didn't work, but now it works. One question - did you always do nudge from main menu or console? I generally did from console but it didn't work till main menu which I think I saw you do in the video. i think I tried buildings in nudger but I'm assuming I just didn't do some required things to get it to work. When I get the next map done I'll try again. How much of the mod was done before you used the buildings in the nudger? EDIT: Oh ok my thing when I try to do that says 'Found Invalid Provinces" that explains a ton. So you were giving the correct info, but it turns out there's something wrong on my end, meaning another 10 hours of searching...yay... But hey. You gave me the answer "Yes it can work on a mass naval map" which is half of what I wanted and I learned what the issue was. Cool! Thanks man.

Shadow Wolf oh cool glad it’s working, if you have any problems let me know, and if u need to send pics of errors I have discord too Rebelsj21#4351. Happy modding

@@rebelsj2159 So oddly enough a friend of mine wanted me to start his mod for him because everytime he tries it crashes horribly. And in the beginning before I sent it to him and only one state had a nation or any details, I did the same thing with nudge and...nothing happened. This might explain it - I was doing that all along but it wasn't working so I think the worlds needs a certain amount of states and nations before nudge can actually generate all of the buildings which would make sense. Also I tried looking for your discord and IDK if I was doing it wrong or if you put the wrong number (I am fairly new to it) but it wasn't working.

challenge gamer tech is super complex and very annoying, I’m currently adding it into my mod, I will try to make an easy tutorial soon

Premiere Ball hey, can you add me on discord? It’ll be easier to help there with pictures. It’s Rebelsj21#4351

Thank you. For the crash do you have any other errors, check the bottom of the error log some hide down there. Weather positions will really never crash your game I still have that error cause I’m too lazy to do the weather. Make sure every province has a strategic region cause that will crash your game if some provinces don’t have a strategic region, if you need any help dm me on discord I’ll help more there cause you can share pictures, mines Rebelsj21#4351

Rebelsj21 that’s the only thing in the error log. Nothing else but the weatherpositions.txt error.

Hm that’s strange, normally you should have a lot of errors, I apologize also if I take long to respond I am in school throughout the week days. Later today when I get home I’ll look into what happened. Have you got every province into a strat region and state? Make sure all your state files have a state category, and atleast 1 manpower in “manpower =“ also make sure you have the default focus tree in your mod. Those are just some things that might crash it

Rebelsj21 I have everything you’ve told me in my state.

I’m not too sure. Is it possible you can send me your mod folder on discord that way I can look at it? That would be easier

did u fix it yet? cus this seems similar to me

@@shadowbadgercat I fixed it by the “replace text” in definition, just how he did in the video.

You can only have a maximum of 20,000 provinces. Anything more will crash the game or ruin the graphics.

go to your mod setting and click on mod tools and their you go

Protein Bepis either you forgot to generate state files or it might have not worked or broke, you can regenerate in map gen or you can use a number lister online, list all your provinces out, check definitions file to see how many you have, then copy and paste all the numbers into one state file, then break them in to smaller ones in the nudger as you please. Lmk if you need help

@@rebelsj2159 Hi Rebel, I've put all the numbers into one state and yet I'm still getting the pop up, any idea what to do now?

Protein Bepis how many of these errors are there? And check the number on them. Tell me if it’s something like this: the error says province 100 lets just say, but in definition you have only 50 provinces. If that’s the case then your province map probably has errors, let me know if it’s like that

@@rebelsj2159 Yep, the error message says up to Provinces 13,217 when in definition it says I only have 7924. What should I do now?

Hello mate, did you managed to solve that? I have exactly the same issue

fix your path on .mod file

German the map generator does have a state generator, it just dorsnt work too well haha. Id recommend combining all your probinces into one state file like I believed i showed in the video. Make sure your state file has a state_category or the game will crash.

George hey, this is a pretty complicated thing to do and would take a large amount of time. I can explain it in full but it’d be very in depth and very hard to do, however, what I’d recommend is to copy the base game province map, and height and terrain and river maps, edit them by removing the areas you don’t want on the map, and put them into map generator and generate a new map that way. If your confused let me know.

@@rebelsj2159 Well, I could make some nice maps. But after the update did not work out. Will you have a version of software pro 1.8+?

George what do you mean software pro 1.8?

@@rebelsj2159 What i am want said is that going an update (mapGenerator) for the version 1.8.1

@@George-zv3qn The map generator won't be updated again - as he said in the video it is an easy fix to make it work for 1.8.1 though.

PoZzeidoN check your mod files? Make sure your mod uploaded correctly and that the map files are the ones you generated and not the base game, that’s weird tho.

were you able to find the solution? My game is doing the same thing

@@davidgarrett574 im sorry but no.

Rebelsj21 mine are the generated ones. There are no errors, and everything is put in correctly, but it still doesn’t load. It mainly ignores the “replace_path” things, as things like the edited bookmarks are the same when they shouldn’t be. What do I do

Are you sure that you changed the names in the localisation? "state_names_l_english"

same i'm not sure what to do.

Also my provinces have really messed up lines around them

when you create the states it generates files in user/documents/paradox/hoi4 or however your file structure is, you need to copy these into the mod folder to make them "stick"

Change the number in the mod description file from 1.5.4 or whatever version it is to to 1.9.*

@@1HardCoreGaming1 yeah i know. but some files are fucked :) (I have fixed it for myself)

Creating a mod will always pre-set it as the current updated version of HOI4, and DLC requirement is probably no.

@@maozedong6762 Thanks

Békési-Marton György yes this is a tutorial on 1.8.1. You will get many errors though as the map generator works off of 1.5 I believe, that’s why you have to go in and manually fix many of the errors. DLC is up to you if you want to use it in your mod or not. Just when posting it on the steam workshop make sure to list what DLC is required and which is not

@@rebelsj2159 Thanks

Yes, id say its actually easier to do this. You have to draw in the provinces in paint or photoshop manually though, and manually enter them into the definition file. Its actually very simple once you get the hang of it. In the ingame nudger, in database tab i believe there is a rgb generator, it will give u random colors that arnt in use, use the color it gives you, draw the province, then enter into it all into the definition file

Sorry, i just started learning today, what is a definition file?

Frozen Mouse it is in the map folder, definition.csv or something. I explain it somewhere in the video i think but each line of code represents a province, go to the bottom, copy the line above the last one, and paste it below, change the first number up one, its like 1, 2, 3, then yours should be 4. The next three numbers are the province RGB color, in that order, red, green, blue, then enter if its a land or sea province, probably land, then true or false, this is whether or not its a costal province, true means it is, then the terrain, jungle plains, hills, etc, lastly the continent, just put 0 it doesnt matter too much, all seperated by ;. Look at the other ones for reference, hope this helps

Thank you so much! you've been alot of help! I'll let you know when i finish it

Awesome! Let me know!

чёрный пёсик sorry for the late response, there could be a bunch of issues occurring, under paradox/hoi4/logs there should be a error.txt or error log. This will list any errors

Use a map of just north america in the MapGen
