Modifying Nifs in Oblivion

[Zetaman]

Hello all, I am relatively new to modifying Meshes through blender and then converting and checking in Nifskope. I have been trying to make a modified version of the Muscle girl race on Nexus. I basically have taken the Nif and readujusted the meshes proportions to be more thick and endowed so to speak. However, after I export from blender and replace the old nifs OBJ with the new modified one, it appears in game with color but no specular maps. Its a flat diffuse map with none of the original materials. Im wondering what im doing wrong or what im missing to get the texture to show up correctly in game.
