Levels of detail can be added and modified in the object panel. The object panel also contains new tools for generating levels of detail, setting up levels of detail based on object names (useful for importing), and clearing an object's level of detail settings. This is meant as a game engine feature, though the level of details settings can be previewed in the viewport.
