Thank you for your interest in Propaganda Campaigns!

In this guide you will learn how to add your own posters to the mod. Basic knowledge about HOI4 modding is required for this guide, as I don't want to concern myself with questions like "how do I edit a mod file" or "how do I upload something to the Steam Workshop".

If you are new to modding, please check out the HOI4 Modding Wiki[hoi4.paradoxwikis.com] or the numerous YouTube tutorials on this topic. Thank you for understanding.

Unfortunately I currently have very little time to work on this guide and it might take a while for me to finish it. All materials for creating a submod can be found below, so please work yourself into a subject if you can't find information about it in this guide. Sorry for the inconvenience.

Anyway, have fun modding!

All necessary documents can be found here: GitHub[github.com]

In this guide we will work with the files linked above. As an example we will add new posters and propaganda campaigns to Poland. (Lucky you if you want to create a submod for Poland)

Included in the documents are the following:

• A complete mod template for Poland
  
• The original Photoshop documents for creating posters

The Photoshop documents use Smart Objects and frames. Please see for yourself how these features work. You don't need a deep knowledge of Photoshop to edit the images however.

Note: You can download files on GitHub via the green button "Code" and then "Download ZIP".

To help you find your way around, here's a list of all the files you will need for the mod. I also included some information for what each file is used. As you can see, you don't need many documents to build your submod. I've tried to make the mod as lightweight as possible.

This is where you enable the "Propaganda Campaigns" view for your country:

Here you can add new "Propaganda Campaigns" and "Hostile Leaflets":

Here you can define which decisions should be activated if the enemy drops a "Hostile Leaflet":

This is where you store the tileset for the posters:

This is where you tell the game which tileset to use:

Here you can add your translations:

The first thing you want to do when creating a submod is to assign the necessary country flags to your nation so that they will be recognized by the main mod.

To do this, you need to modify the following file:

The document should look like this. Of course, you will need to replace "POL" with the country tag of your nation.

The first two lines are the place where the magic happens. In the first line you tell the main mod that your country should use the features of Propaganda Campaigns. This includes the GUI in the decisions menu, as well as departments and preparations.

With the second line you can specify if your nation can receive Propaganda Leaflets from other nations. Note that any nation can send Propaganda Leaflets to other nations as long as this is enabled in the target country. This option is optional but recommended.

The next line is relevant if you want to overwrite the default poster of a country that is already included in the main mod (e.g. Germany). This option is optional and will disable all standard Propaganda Campaigns (poster decisions) for that nation.

The next line gives you the option to use a special variable for the recognition of the poster tilesets in addition to the country tag. This is an advanced, optional function, which will be explained in more detail later.

The last line was used for the detection of obsolete submods. This feature is no longer used however, for which reason this option is now depreciated.
