Help with modding textures

[wanderindarkness]

Hi to all, this is my first post here so if there's any customs you'd like to introduce me to I'd love to hear. So here's the situation, I have created a custom model for a Katherine Warren nude mod. I've gotten everything except uv's and i've also got an odd texture. Since the body is mostly the same color I can texture it but there's an odd grey pattern that covers the model. It's only slight but it's enough to change the color of the body so that it does not perfectly match the head. I've attached the screenshots of what it currently looks like, any help would be amazing.I've double checked all of the layers and channels of all the texture files i currently use in the mod. Which are the albm, atos, nrmr, and the wetmask.
