How to increase AI desire to commit incest marriage and drastically decrease/forbid non-incest marriages?

[notwaaagga]

Far Eastern Cultures CK3 screws up Mandatory Consanguinity mod in a way that i can't enact family-exclusevely marriages anymore, unless MC loads after FEC, but then mazdayasna and messalian are left with that nasty "cousin marriage". How do i force AI not to marry outside of family, by editing FEC files?

Mandatory Consanguinity  isn't updated yet i think. So its old and maybe not working.

Shooting from the hip, looks like these are the necessary steps:

Copy the MC triggers over to FEC, in there replace doctrine_consanguinity_mandatory with divine_marriage_doctrine and replace several occurances of

relation_with_character_is_incestuous_in_my_faith_trigger = { CHARACTER = scope:recipient }

in 00_marriage_interactions.txt (copy from the game files and place in FEC) with

OR = {

    relation_with_character_is_incestuous_in_my_faith_trigger = { CHARACTER = scope:recipient }

    relation_with_character_is_not_incestuous_in_my_faith_trigger = { CHARACTER = scope:recipient }

}

 just like MC did.

 

It might work with the interactions file in MC, but some new CK3 version stuff might be broken then.
