Set of five asteroids, each one in five different LODs. Complete with diffuse and normal map.

Triangle count:
LOD0: ~1500
LOD1: ~750
LOD2: ~300
LOD3: ~150
LOD4: ~50

Of course you could use each LOD seperately, but there are also two different kinds of prefabs for each asteroid:
High Profile using all five LODs and a mesh collider using LOD4
Medium Profile using LOD2 to LOD4 and a collider using LOD4. Good for mobile applications.
