From what I have seen of the other Beth games, the textures are not entirely assigned in the game's data files. Rather they are also assigned in each individual .nif (mesh) file as well. You have to open up the .nifs with a program like
Nifskope. In Skyrim's .nif files you do it this way:
CODE
Open .nif file.
Expand the NiNode on the left.
Scroll down to each NiTriShape and do the following in each:
Find BSLightningShaderProperty and expand it.
Go to BSShaderTextureSet
Go down to bottom pane and expand the Textures line.
Edit the values of each *.dds file line. Leave off everything in the path before the textures folder (so it looks like: textures\somethingfolder\somethingfolder\mytexturefile.dds)
It might not be exactly the same with the .nif files of Morrowind, but it is probably pretty close.
