one is black and white and seems to be the mesh form that is lingering behind on your invisible underwear sims(I say that because a nude skin would be the next step). package files created by Color magic you end up with two textures that are editable and have the RGB layers and alpha layers. NOt sure if this has anything to do with it but in the. With female bodies the default underwear is always visible - even the textures are empty images - I search through the 4 895 textures and - I'm sure - there is only 2 textures resources (normal and Multiplier / Specular) to define the female underwear default texture. And I really don't understand why it does not work for female bodies. But It seems this method works fine only for male body. To do this,it's simple - I thank - we only need to set an empty texture for female and male default underwears into the normal and multiplier / specular texture of the default underwear.

It works perfect for male bodies but not for female as you can see on the joined pictures. So I try (first phase :-))) ) to make TS4 female and male nude skins.
