Body Hair Traits 2.0.1

For men: This mod adds 7 new traits that replace the game's body hair gene, each trait visually modifies the character with one of the six vanilla's body hair genes: sparse, average, dense, sparse (low stubble), average (low stubble), dense (low stubble), and a new smooth variation with no body hair. There's very little difference between the normal variations and the "low stubble" ones. Only male characters are affected and the NPCs are seeded with a random trait (if they don't have one already) after the age of 18.

 

For men and women: Since version 1.1.0, the dynamic pubic hair trait has been added with the 3 states: Hairy Pubes, Trimmed Pubes and Shaved Pubes. This trait, unlike the Body Hair, is not congenital and it's seeded by script, it also does not change the character portrait with any gene.

 

Since version 1.3.0, a new congenital "bad trait" has been added. With "Alopecia Universalis" character will have no hair on their body. (note: if you're adding it from the Ruler Designer, you have to manually remove hair and beard.)

 

For the court: The court position "Royal Shaver" will be available for county or greater titles. The employee rules will follow the martial rules of the realm. When employed, all courtiers and the liege will slowly increase the Hairy Pubes trait to the shaved state.

 

Feel free to report bugs and give suggestions, as this is a very clunky genetic mod. Special thanks to Luther Slade and Cheri, for the seeding traits structure is just a simplified version of the Carnalitas one.

 

⚠️Compatibility: The mod should be compatible with any other mod, but if they change the body hair gene, they should be loaded after this one to avoid errors. If using a total conversion mod, the log might throw errors during the initial play, yet these should not persist. If you found any conflicts, please share.

📃 Notes from the version 1.6.0 forwards

 

The update is a 'revamp' mostly edited by Claude AI and Github's Copilot. Things changed so there's less strain caused by the scripts. The traits are no longer distributed as a simple random list or as copy of a 'father' character. Some things like the decision to shave body have been removed, though shaving pubes is still present. Religions do get doctrines about pubic shaving, but I couldn't manage to make them appear on the UI. The new architecture is described by Claude as the following:

 

Hairiness is a number now

var:bh_hair_value, 0–100, stored on every character including women, so maternal inheritance works. It is built as:

1. baseline 50, shifted by heritage (flavour pack only)
2. blended toward the mid-parent value at bh_heritability_value (0.62)
3. plus noise of ±22
4. plus a few points in the mid-twenties and again around thirty

then banded into the existing traits. Two consequences worth knowing: mixed dynasties now produce sensible intermediate children instead of copying the father's tier, and you tune the whole distribution from seven numbers in bh_script_values.txt instead of editing four random_list blocks.

The old father-only check has been replaced entirely. It also read scope:real_father in contexts where that scope did not exist, which is where most of your error log came from.

Total conversion support

The failure mode was never the logic — it was that faith:ashari resolves when the file loads, not when it runs, so no guard helps and a TC that lacks the faith gets a hard error. The fix is quarantine:

• Faith attitudes are assigned by a heuristic over doctrines every faith is guaranteed to have (doctrine_pluralism_fundamentalist, the adultery and deviancy crime doctrines). Any map, any custom faith, no named references.
• The flavour pack then corrects the four cases where the heuristic is wrong, and it matches on religion rather than listing forty faith keys — so reformed, hybrid and custom faiths inherit the right attitude for free, and there are four references to break instead of forty.
• Assignment only ever touches a faith that has no attitude yet, so a faith that declares one itself is never overridden.

To run on a TC, copy optional/zz_bh_flavour_vanilla_TC.txt over common/scripted_effects/zz_bh_flavour_vanilla.txt. Do not delete it — the core calls both effects by name.

Distribution

Indo-Aryan and Iranian cultures move to the top tier (+22), where the anthropometry actually puts them; the old buckets had them mid. Turkic and Mongolic are separated from East Asian rather than sharing one bucket. Only heritage keys your 1.19 log proved valid are used. A comment in the flavour file lists the Sub-Saharan and All Under Heaven heritages worth adding once you have checked their keys against common/culture/pillars/ — until then those cultures sit at the neutral baseline, which is dull but errorless.

Religion

The -45 realm-wide opinion penalty is gone. Nobody can see this, so it is a secret now (secret_grooming_transgression), criminal under an illegal doctrine and shunned under the others, kept in sync by bh_refresh_secret_effect. bh_expose_grooming_effect is the hook for spouses, lovers, physicians and the Royal Shaver to discover it.

What stays public is what plausibly would be: piety drift and clergy opinion via faith_modifier on the trait.

Performance

Removed: ai_character_pulse, on_birthday, on_weight_changed, on_title_gain, and the every_living_character sweep at game start (which now means 20,000+ extra characters on the 1.18 map).

What remains is one yearly pulse gated on bh_is_relevant_trigger — player, any landed ruler, or anyone in a non-AI character's court — plus lazy seeding from the places that actually read the value. Most of the world is never touched.

The Royal Shaver runs from the employer on quarterly_playable_pulse, looping every_courtier: one scope per court, four times a year, instead of a trigger per character per pulse. That also kills the 89 "event queued twice with the same data" errors, which came from several on_actions firing the same event on the same character on the same day.

Decision intervals went from ai_check_interval = 3 to 24–60 with ai_check_interval_by_tier on top, and the ~20 repeated faith = { has_doctrine = ... } lookups per ai_will_do collapsed into one cached bh_faith_attitude_value.
