No matter how many times I run TES4LODGEN and TES4LL, I never get LOD in modded areas to be as gorgeous as vanilla Oblivion.

In vanilla Oblivion areas, it is fine and everything's beautiful as it should be. However, what I get in different parts of Tamriel is different.

I see empty land and no statics. Once I get closer, they pop into sight. What are the tricks of getting good LOD? I want good LOD for Elsweyr: Deserts of Anequina and TWMP Hammerfell.

You need LOD meshes for all statics you want to appear in the distance. LOD meshes have the same names as their proper versions, but with _far added to their file name. TES4LODGen will only work for statics which have LOD meshes. If the mods you are using don't have them, the statics will pop in once you get close. The only thing you can do about this would be creating the LOD meshes yourself, but depending on the complexity of the statics, this could be difficult to get right. LOD meshes need to be far less complex than the proper meshes, since too many distant statics tend to slow the game down a great deal.
