I'm very new to the world of adding mods to skyrim so I was hoping some of you good folks could recommend a decent mod to repair the gaping holes that have been left in the game world by it's graphics artists, probably because they were rushing the game to meet the release date. The one I saw today was a large rock with the bottom portion missing with the terrain visible behind it...I'm all for new content but having the pre existing terrain left incomplete really bugs me!
