Thank you both!
@ SubRosa - I used NifSkope to do the retextures just like I did for the Oblivion retextures, and they looked great and loaded easily into the Morrowind CS (after several renamings) - but once in the CS the new textures didn't show up on the meshes.

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)
THIS is exactly how the guy on the internet described how the Morrowind file system works too, so Ghastley is right that I need to study the conversion information for Skyrim!

I believe the texturing node is different in each of the three - Morrowind, Oblivion and Skyrim. They added new graphic capabilities as DirectX provide them, so the nodes all have different names.
The interesting thing is that the Blender import/export uses Morrowind format for Skyrim and there are steps you do in NifSkope to adjust from one game to another. That means the conversion process is documented for Skyrim, and you can learn a lot from the tutorials.
@ Ghastley - This is some great info, especially learning why/how the nodes differed between the games (why I couldn't bring Morrowind NIFs into Oblivion, lol) and definitely about those steps to adjust NifSkope between games - that is something I need to learn!
I have no idea how to make a mesh, I only use NifSkope to retexture existing meshes to my own liking and preference.
Somewhere on the internet I read that problem had to do with the file naming system in Morrowind (and I believe it, the file names - even the Bethesda Official ones - are like "a," "b," "x," etc - VERY short, and very few file divisions too.
From what I can figure out from the CS warnings while I was uploading the meshes, the Morrowind CS only allows for 32 letters (to include the path names).
So you have to force NifSkope to shorten the path file as much as possible, then name your file with very staccato descriptors:
Example:
in_wall_wood
ex_wall_stone
(interior, exterior).

Since all the mods I loaded up were/are working smoothly; I looked to them for some clues to what I was doing wrong.
Some of the mods just dumped the new textures loosely in the texture file and some divided them into small-named files:
Example: Ice's files are divided by the mod name:
(Ice's Hideaway file name = "1ih" Inside the file there are few to no divisions, any there are named "a," "b," etc.
So technically, you have to either give a short code name and make your own list so you know what each mesh/texture is; or try to use mini-descriptions (which is what I'm attempting to do in my personal Morrowind meshes/texture files right now - just revamping file names on everything I uploaded for my own use before it grows too large to fool with - like what happened in my Oblivion mesh/texture files, lol)
Thank you both, very much !!!
