Graphics modding

There are two parts to graphics modding:

  • Assets (images or models), stored inside /gfx folder
  • Logical names (starting with GFX_ prefix) mapping to these assets, defined inside /interface/*.gfx files.

Logical names are then either referenced from other script files, or are based on naming convention hardcoded in the engine.

EditorsEdit

Some recommended editors include:

FormatsEdit

FoldersEdit

CharactersEdit

Main article: Portrait modding

This folder contains bits of faces that are stuck together to form portraits.

Coats of armsEdit

Main article: coats of arms.gfx

Contains flag frames and CoA pattern & frames.

FlagsEdit

Flags are used for titles above baronies, but only for religions where has_coa_on_barony_only = yes. The game typically crashes if the flag is any of the following: is not 128x128, is not 24-bit, or is uncompressed.

Warning: a missing flag for a title in flags\ folder will cause wrong flags to appear for most titles, due to a shift. a good way to work around this while working on other aspects of the mod, is to give the nations placeholder flags.

FontsEdit

See [Tutorial] Custom Map Fonts.

InterfaceEdit

Main article: Interface modding

Main game loads from /interface/ for christian religion group, but some assets are overridden when playing religions from other groups:

  • from /indian_interface folder for indian_group religion group
  • from /muslim_interface folder for muslim religion group
  • from /zoroastrian_interface folder for zoroastrian_group religion group
  • from /jews_interface folder for jewish_group religion group
  • from /pagan_interface folder for pagan_group religion group

New religion groups load from /interface/ folder, and cannot have their own interface.

Mods cannot override assets in religion group folders, as the override is only processed for main game.

Loading screensEdit

For optimal compression, loading screens should be saved with DTX1 compression / no mimaps.

The order loading screens appear is random, except:

  • load_0.dds, which is used as splash screen
  • the image with highest file name (ex: load_13.dds) has a far more likely chance (50% as of patch 2.8.2) to appear first.
