i made a model in blender, it is just a plane. i exported it into unity. the problem is, in the preview box of the prefab the object shows up perfectly, colored and everything but when i drag it into the scene the mesh shows up but it is completely transparent i can only see the vertices and edges but no color. i know the normals are fine because in the preview they are.
Plane only has faces on one side. Be sure you are not viewing wrong one in scene.
