Alright, if I can create random coat of arms gfx by religion only, then I can create a set of heraldic symbols/styles for each Catholic, Orthodox, Pagan, Sunni, Shia, Zorastrian, etc. for them to use instead of the flags folder, right? I presume I would need to use the same code used for Muslims so titles don't use the flag files but use a random one.
Is it possible to create two COA gfx sets, for example, for Catholics, one used for dynasty coa and one used for title coa?
I'd like to do a mod where all the COA/flags are random for everyone, but certain religions get different symbols. Would be nice to do culture too, but oh well.
