So I followed the instruction on the faq but the mod still doesn't work.I put all the meshes in the mesh folder and textures in the text folders now there was one other thing in the texture folder it's called the land default tga do I get rid of that?.and the mod came with something called reset to vanilla.mit I put that in the texture folder as well was that a good move?.and the faq said something about clicking the mod to turn it on in the data files but when I click the morrowind icon and go to the data files the mods don't show up what am I doing wrong?.

I have no idea what SWG FAQ you're talking of, but the enclosed ReadMe file has all the details on what the different Sky files are for and where to place them (if you want to use them... since some are optional variations of the same thing)

The .mit files are for changing the ini file with the enclosed "MorrowINI" program. This is optional, since most people tweak their own ini manually.
The Reset to Vanilla.mit does as it is named.
None of them go into the Textures folder.

Basically, install the mod just like any other mod. Place the correct files into their designated folders. (as described in the ReadMe)
This mod has no esp, since it is a simple mesh/texture replacer.

Be sure to also install the 'Night Sky Fix' from the same page, and install it last.
