After noticing that Dune (in Elsweyr) wasn't showing up as a LOD, I downloaded and installed RAEVWD Anequina v2. I can see Dune now... most of it, at any rate - the city floats above the ground because the walls aren't showing up. I can see the rest of the city fine, though. Which files am I missing?
I haven't noticed any problems with the LOD for Dune with RAEVWD, other than the lights on the windows not showing up in the distance (which isn't a problem, of course - it's a feature request). I should probably mention I installed all components for Elsweyr except for the trees.
Did you verify you have everything in the architecture folders installed, and did you remember to run TES4LOD again after installing the Anequina addition to RAEVWD?
