LOD generation should be one of the last things you do to your worldspace. And it does matter if you want distant terrain and objects such as trees and buildings to be visible in your world. Once you generate the LOD for your world it is a good idea to walk your entire space to see if you are happy with the results or need to change a few things to give it a more natural look. But if you do change the lay of the land or add more objects such as trees, rocks, or structures you will have to regenerate the LOD. With the new tools that are available for LOD generation it is a much easier and less stressful than before. http://www.nexusmods.com/skyrim/mods/4727/? http://www.nexusmods.com/skyrim/mods/62698/? Make sure you download the Vanilla Tree Billboards file also. Good Luck with your mod. Thanks a lot. Couldn't find a straight answer anywhere, you really helped me out. Cheers.
