Just so we stop hijacking poor Trance's thread.
I finally figured out WHY I been having such a hard time making a hi-rez workable UV for that silly wall piece....Apparently some mod I have loaded moves or rotates one of those two wall pieces. https://www.dropbox.com/sh/d8kmrjmt186uahi/Ii44NzpgMQ. I just loaded in the CS for the heck of it and was in shock when it agreed with Blender. I been wracking my poor brain all night why what I was seeing in Blender (where I KNOW I had the walls lined up perfectly to each other) was not matching what I was seeing in game. I've spent the last six hours trying with varying textures thinking textures were the problem. Loading up only Morrowind.esm and seeing Blender agree with the CS was my Aha! moment. More to follow later after sleep.
