I'm attempting to generate LOD for a mod that alters a small area of Tamriel. The area is just northwest of Whiterun and only affects three cells, all in the same quad, -8,0. I have tried Oscape, Tes5LodGen, the CK itself and DynDoLod, with no results. Not sure what I'm missing. I have done LODs for custom worlds dozens of times without issues but this has me stumped.
When I load up the mod in Oscape, I tick Skyrim.esm and the mods esp (there is no worldspace other than Tamriel in the Mod). I select Tamriel tick Feature map and Surface map then extract. When the preview of the height field comes up, all is good but the area where the changes to the landscape are made is empty (black). I don't know why. All the changes made are really minor. The land is raised slightly and the snow is removed from the mountain in the area and replaced with a vanilla grass texture, that's it. When all is done and the new files are in place, from a distance the snow is still present on the mountain, and there are holes in the landscape where the land has been raised. But as you approach the area and the lod fades and the actual textures appear, all is how it should look.
I tried importing the Tamriel worldspace into the mod but all that did was crash the CK (which was kind of expected, I even went as far as trying to rename Tamriel worldspace to match the mod, but again crash). Regenerating the Tamriel LODs in the CK took almost 17 hrs with the same results. The mods author said someone had done something similar for one of their other mods but that person hasn't been on the forums for a while (didn't mention who it was).
I would like to be able to help him as I have seen a preview of the mod and it is very well done and running through it quickly has put a lot of time and effort into it. The only problem is the LOD.
If anyone has any suggestions or a solution any help would be appreciated.
