The Pathfinder Cosmetics mod, by default, adds a LOT of cosmetic options for the basic Kevlar, Predator, and Warden armors. If you're anything like me, you like your armor to look like the armor it's supposed to look like, so here's how you can disable the cosmetics from showing up on other armors:

1) Go into Pathfinder Cosmetics' XComContent.ini.

2a) Comment out (put a semicolon in front of) every line that starts with +BodyPartTemplateConfig, with the exception of the ones in the "Pathfinder Helm" section as those are for helmets. If that's too much work, see 2b instead.

2b) If you're as lazy as I am, just delete the whole contents of aforementioned XComContent.ini and copy+paste the contents of this Pastebin into it instead: https://pastebin.com/YGR0nij3

3) Save your changes and you're done!
