Paradox has released an official Maya exporter which opens up easy and officially supported 3D modelling in their games, if anyone has any experience with using Maya and 3D modelling programs then please let me know so we can get in contact, as having some custom 3D models for the mod would be absolutely amazing. The exporter is free to download for anyone with a Paradox account and works with HoI4 and Stellaris fully (when they are released) and is partially compatible with EU4 and CK2 to make unit models. For more details read the post I linked to. If anyone feels like messing around with it in a test before posting here then this is the official paradox guide for using the exporter (note that Photoshop is not necessary, alternatives like GIMP work as long as you can export to a .dds)
'A Game of Thrones' is a user modification for Crusader Kings II not affiliated in anyway with Paradox Interactive or the rights holders to 'Game of Thrones' and 'A Song of Ice and Fire'.
