To add a new portrait, you have to update three files:
common/graphicalculturetypes/[whatever text file you have there].txt
common/cultures/[whichever text file that has the culture that you would like to edit].txt
interface/portraits/[you can name this file whatever you want].gfx
Text files in common/graphicalculturetypes/ define graphical culture types. Graphical culture type is an umbrella tag for all culture-dependent graphics, including unit sprites, holding icons, and portraits. Since you are adding a new portrait data, you need to define a new graphical culture tag. I recommend that you make your own file so that all you need to do whenever CPRplus gets updated is to move that file into a newly installed CPRplus.
Let's suppose that we want to make a new portrait set called "prussian". Make a new text file in [CPRplus folder]/common/graphicalculturetypes/, and simply add
Code:
prussiangfx = {
skin_tone = 0
}
Note that the "skin_tone" entry doesn't change skin tone; the entry is referenced in the event characters with different "skin_tone" entry have a child and result in a "mixed" child. I'm not sure how exactly this works, but you can basically expect a mixed child between chacaters with skin_tone values of 0 and 3 to be born with some graphical culture with the "skin_tone" value of 1 or 2. I don't know which graphical culture actually gets chosen, though. AFAIK it's not entirely random. In vanilla, some of the earlier patched seemed to prefer the Turkish portrait, while more recent ones seem to pop up the Cuman portrait more often.
Now that you've defined a graphical culture type, you must give that graphical culture type to the culture(s) you would like to have it. So, in this case, open up common/cultures/00_cultures.txt because that's the file that has all the cultures whether you play with or without SWMH. Look for "prussian" and do this:
Code:
graphical_cultures = { prussiangfx ugricgfx }
Note that I kept ugricgfx so that Prussian characters use Ugric unit sprites. Basically graphical cultures get loaded in this order, leaving whatever graphical culture element is missing to the next graphical culture defined:
Code:
[culture group] = {
graphical_cultures = { 3 }
[culture] = {
graphical_cultures = { 1 2 }
}
}
So if you have this -
Code:
celtic = {
graphical_cultures = { westerngfx }
welsh = {
graphical_cultures = { bretongfx celticgfx }
}
}
Welsh characters will use bretongfx's portrait, then will use the Celtic unit sprites, and will use all other graphical culture stuff from westerngfx (e.g. councilor sprites, holding icons...)
Lastly, you will need to add portrait entries for the graphical culture you defined. I won't get too much into detail here. Just make sure that, for every entry that starts with "portraitType", you have the newly defined graphical culture type's name. For example:
Code:
portraitType = {
name = "PORTRAIT_prussiangfx_male_early"
. . .
