Do _s.dds & _sk.dds textures work properly on bodyslide belly?

[indyskyho]

Using UUNP and everything seems to work fine, except the stomach always appears to be completely flat color in any lighting when scaled to larger sizes.

 

I can see the effect at certain specific angles if I rotate the camera a lot, but in general the belly seems to just be the flat base .dds texture...

 

Is this a common thing? Is there a way to enhance specular maps and subsurface ENB tecture effects on the stomach to match the rest of the body?

 

Thanks
