I am straight up new to the modding concept and have no idea how to get this mod in particular to work. after downloading the file I am unsure where eactly to put it in the data files of the "Morrowind" files. I believe it would be under textures, but am unsure if that's it or it would then continue to be moved to file location "bb" with in the "textures" file or if Im completely wrong on this whole thing. please help.
