No material and prefab connections


I’m working with Unity and I was really happy because of that until now. Well, I turned on Unity, and SUPRISE: all my scenes don’t work, any prefab and material connections are lost, every material is completely empty, every bumpmap is not a bumpmap and prefabs are not connected to existing objects in the scene.

Is there any way to solve this problem? Please answer because I can’t work with the risk of losing my work again.

This is caused when the Library or Cache folders in your project are moved or deleted. These folders should be completely left alone, and always included when you back up your project folder.
