Where is it? How is it done? What actually makes a character decide to use a particular portrait? The example mod simply overwrites an existing portrait, so if I was using existing cultures I could IN THEORY dig through the entire list and figure out what is which culture (but I hella ain't doing that) but it seems as if you literally could not add a new cultural group for portraits even though everything else about it seems open to mods: there's a KingsRecipe.binary in /Portraits that must be doing something. Is it documented anywhere?

Also defs/Characters/Portaits, I assume, is misspelt.
