So is paradox interactive ok with using Paradox models/created assets, for mods for other paradox games?
I think you cannot use for game a Paradox feature that was created for another game.
I mean, you can create your own Roman Empire units for CK2, but you cannot take those of EU:Rome and "pack them" as a mod for CK..
Edit: found it ( I remembered to have read it somewhere...)
7) No material from one Paradox IP(Game or DLC, includes any content in them) may be used in a user mod, unless that user mod can assure only people with that other Paradox IP installed can use it. If doing that is beyond the technical ability of the particular mod maker or it is impossible then they cannot be used.https://forum.paradoxplaza.com/foru...user-made-mods-and-edits-of-pds-games.708039/
