Every game that uses a lot of objects especially in a large world sooner or later must find ways to optimize the draw overload. Here EzLOD comes into play.
EzLOD is very simple and it was intended to be this way. It must interfere as little as possible with your project and therefor it must be lightweight in all the aspects. It comes with 2 components, one that tracks the camera and one that handles the LOD changes at the object level. For every object that must be displayed with LOD, a special GameObject must be created, that will hold all these separate LOD levels. Just attach the script, setup the meshes and the distances and that's it. No need to setup links between objects and camera, it just works.
Very simple to use but should very much make a difference in very large worlds with lot of objects.
