Do you have both the textures in question? The normalmap (usually suffixed _n.dds) is just as essential, but Nifskope doesn't tend to indicate that. If the textures are all present and correct, the only other thing I can think of is incorrect weighting, though that shouldn't be the case if Nifskope pasted it without complaint; in which case the advice of someone a bit more experienced may be required... yeah i have both >_< ugh, im probably giving up lol, ive spent all day on one thing.
