Genetics Overhaul Collection: Better Inheritance (Preview)

Finally I made one of the most challenging and wanted projects I planned to release. This mod collection provides completely another genetics system.

The Better Inheritance module adds more specific rules for inherited attributes.

You possibly know that often children have a skin color or even type that different from the parents' ones? That's because the game considers only skin hue when applying the genetics. Skin hue is a table of warm, neutral, cool skin tones (+ occults). Then it applies the blending between parents skin tone, and you'll receive an approximate skin tone for an offspring.

This module makes the game consider skin value (how dark or light the tone is), type (natural / fantasy) and archetype (Asian, African, Caucasian and so on):

Besides, I turned off skin tone blending, so an offspring will have either skin 1 or skin 2. MCCC setting 'Inherit Parent Skin Tones' makes similar thing, but it works only in the live mode, while this module works in CAS too. And it's very helpful if you want this feature to work with the main mod, because it requires turning off that MCCC setting.

Plus, the mod also makes the game consider archetype of eyes and hairs to avoid a strange combination of dark skin, white blond hair and blue Asian type eyes.

Check the compatibility status HERE

REQUIRED

Nothing, Base Game compatible

CONFLICTS

With mods that change Client_GeneticTags and with the settings that apply skin tone replacement (this mod will override it anyway). Regarding MCCC, just disable 'Inherit Parent Skin Tones' setting.

This mod has longer Early Access because it's a very complicated mod and I want to test it more carefully. I hope you understand.

Also, this is the most difficult thing I have ever made, so I'll be very grateful if you decide to support me 🙏

Thanks! I'm not sure if I release this version, because it seems that skin blending causes the skin bugs as well I'll make a research one more time but can't promise
