This greeble pack was made specifically to be used with the "Plating Generator And Greebles" Blender addon created by Mark Kingsnorth, as such all models are prepared and arranged accordingly.

The collection contains 271 meshes that you can use to spread across the hulls of your spaceships, stations, roofs of futuristic cities and other projects you may have, in order to quickly make them look much more detailed and complicated in your final renders.

The pack contains various objects arranged in folders ranging from sensors, vents, signs, fuel storage, hatches, scaffolding and many more other random objects and simple shapes.

If instead you're looking for a greeble pack where all the meshes are in one single file please see see this product: "Greeble Kitbash Lowpoly Pack".  But keep in mind that pack is not suitable for use with the Plating Generator addon.
