How to create a religion?

[Nicolette]

I have an idea for makeing some kind of celtic polytheistic branch of christianity and start as a custom nation. The problem is though, i can't find out how to make a religion. Is it even possible?

I dont think that you can create your own religon. If you make a custom nation i know you can chose some religions that dont exist in the game (like nordic) but thats as far as i know.

A custom religion would require modding it in.

Download a mod that adds religions to see how it's done. It's in the mod folder/common/religions. Below is an example of a new group of religions from Extended Timeline. You'll observe that some religions have personal deities and things; there's another folder for that sort of thing.

I would just copy and paste the part of the below relevant to you--like maybe you're just adding a religion to the Christian group and not adding a new group--and change the details within the structure.

mesopotamian = {

flags_with_emblem_percentage = 10
flag_emblem_index_range = { 83 96 }

ashurism = {
color = { 210 210 210 }
icon = 37
province = {
local_missionary_strength = 0.01
}
country = {
tolerance_heathen = 1
defensiveness = 0.1
}
country_as_secondary = {
global_regiment_recruit_speed = -0.10
defensiveness = 0.2
}

personal_deity = yes

heretic = { BEAR_SPIRIT SNAKE_CLAN }

annex = yes
}

south_arabian = {
color = { 140 20 50 }
icon = 35
province = {
local_missionary_strength = 0.02
}
country = {
tolerance_heathen = 2
tolerance_heretic = 2
}
country_as_secondary = {
prestige = 1
land_attrition = -0.10
}

personal_deity = yes

heretic = { BEAR_SPIRIT SNAKE_CLAN }

annex = yes
}

harmonized_modifier = harmonized_mesopotamian

crusade_name = CRUSADE
}
