Hello, thank you for purchasing our product!
We are sorry you had trouble setting up the asset on Unity.
We would just point out that this particular kits you purchased are not setted up in Unity, like, for example our Scrap City Assets. In that case we also added a .unitypackage file with all the prefabs.
This isn't the case, but we divided and collected all the assets by category, since they are a lot and there are many little pieces and parts!
We wanted to make sure they could be used both in Unity or Unreal Engine; if an asset comes with an Unity Package file, we usually add that in the product description.
Hope this made some things a bit more clear!
We are really sorry you had trouble with them.
Thank you again
