Texture issue in nifskope.

I'm trying to port an object into Fallout 4 for learning purposes but I'm having some problems when adding materials to some of the meshes. The issue is that the textures do not display correctly even though they display perfectly in Maya.

Thanks for any help in advance.

If anyone else has this problem, just make sure you invert the textures and it will solve the problem.
