They work with all the Maxis skin details such as muscle slider, age categories, weight sliders and are for both genders and all age groups. They are found by default with Maxis skin colours and act as such. These are not new skins, they are new skin colours.I came away knowing more about the game and some awesome new colours that don't look jaundice or ashy. I could not be more happy with my first, and possibly last foray into the world of TS4 skins. After a bit of research, diving into the clientfullbuild files, lots of backwards and forwards into the game for testing, hex editing to edit the colour swatches because s4pe threw errors, I finally came up with the lightside and darkside skintones. There is a serious lack of dark skin colours, and the light ones have left a lot to be desired. Today I bring you an experiment that came about from the selection of skin colours available in TS4.
