This mod aims to unify the skin tone on Noct's head textures, and to fix the neck seam on official attires as well as (my) Steam Workshop mods showing a lot of skin.
The issue with the seam on official attires is only present due to extra collarbone shadows on the 4K version of the ambient occlusion texture for younger Noct.
The bros also have shadows included on their official head models and those shadows then show up in Prompto's snapshots. Mods showing a lot of skin thus look horrible in photos. I cover those shadows by partially including necks in my outfit mods. For that I need to blend the modded skin with the original neck as much as possible but since almost each of Noct's official head textures contains a different skin tone, I had to unify those as well.
