Well after much toil I managed to get things to work!

Thank you, for all the help. Just one or two questions. I have a very large world space with terrain outside of the havok bug limit that was only there for LOD and look pretty. Some places you can walk right up to cell 64 to 65. Dyndolod has a worldspace size limit too? Does Dundolod also break after that size limit, or what's the reason it's being limited?
And the other question, I have another worldspace on an esp, it never showed up in the lists of worldspaces Dyndolod could generate lod for. I have done terrain lod on it with SSELODGEN64 and it has the lod settings file. There's not much in it, only a couple of trees.
