Older tools occasionally generated formatting tags that the current HOI4 engine rejects. Inspect your exported focus tree file (found in your mod's common/national_focus/ directory) for these common errors:
As of 2026, HOI4's codebase handles national focuses through complex text-based script files located in /common/national_focus/ . While manual coding is possible, it is time-consuming and error-prone. A specialized provides a visual interface to:
Allows for easy mutually_exclusive connections and automatic icon linking. 3. Paradox Wiki's Text Editor Template

Ensure your exported text file is placed in the correct directory of your local mod folder: \Documents\Paradox Interactive\Hearts of Iron IV\mod\[YourModName]\common\national_focus\ 2. Verify the Opening Tags
To help narrow down the specific code or setup issue you are facing, could you tell me: Which were you originally using? What error message (if any) shows up in your debug log? What country tag are you trying to build this tree for?
