after finishing the regions I would like to create a WAC esp for tamriel heightmaps ...as well I have removed all the underwater region dara..and plan to create a seperate esp (like the provinces) just for the seas...

Sounds good! I'll try to be patient.

I finally installed this last night and then ran through (literally) Valenwood and Summerset Isles with a test character.

I am in awe of this work.

I really hope you'll manage to do something similar for TES5 as close to release as possible because I would very much like to work on a part of something like this. And if for some reason I don't make mods for TES5, maybe I'll come back to this and pick something up. It is quite extraordinary work. My deepest respect to the people who've done work on this so far.

It's a shame that the horizontal scale of Skyrim will be pretty much the same as that of Oblivion. How will you edit the heightmaps for it? In Oblivion, you have the heightmap stretched north/south, but Skyrim isn't in the relative center of Tamriel, so that plan wouldn't work. Maybe a fan like stretching where the provinces get wider/more distorted the farther south you go?
