Texture mapping

[rat7894]

I'm trying to add my own weapon to skyrim, iv got the model, and my three texture maps but when I put every thing in to my nif files my diffusion texture map doesn't show up, my specular and normal dose so at the minute I have a black and white version of what I want.

Has anyone got any ideas why it wont find the diffusion map?. (and I and sure I have the right file path)
