A while ago we had a discussion regarding modifying the pieces of armor on the human model. The consensus was that the "unarmored" model should have some pieces of armor, so that he isn't walking in chainmail pajamas. He also has a gigantic crotch bulge that we wanted to hide. In addition, we wanted to distinguish the light and medium armors. I believe gavlig had intended to do this and didn't get around to it, so I took it up.
Here is the commit: https://github.com/Unvanquished/Unvanqu ... 443040d3cd
I've taken some time to annotate the files, so that you now know which piece does what. To remove a piece, simply replace the value with "gfx/null" and it will disappear. I've also presented some default values that I think look okay, but please feel free to change or reset them as you wish.
As follows, here is my proposed "unarmored" human, as well as light and medium armor. Standard human comes with boots and a vest. Light armor adds knee/shoulder pads and a helmet. Medium armor adds arm/hip guards.
