I tried to do it by myself using tesannwyn after I found this website: http://projectmanager.f2s.com/morrowind/2x2/index.html
In the readme that comes enclosed in the Tesannwyn rar there's a tutorial to rescale the terrain from bloodmoon, giving it a 2x size. I followed the instructions and applied them to morrowind.esm(changing the values where necessary, that is same command lines with the correct numbers like map height)but the esp that I get in the end shows no enlarged vvardenfell, nothing looks different at all, and I dont know how am i supposed to achieve the results showed in the pictures in the mentioned site.
I was wondering if anyone has tried this, and maybe could help me pointing what I am doing wrong.
Thanks to everyone in advance,
