so I am new at UE. I created my kitchen in Blender. All the normals of the faces are pointing into the room. Now I import this room to UE. And now some strange thing happens:
As I want to have, the walls are invisible from the outside (the normals are pointing to the inside), from the inside they are visible. But what I don´t want to have:
The sunlight shines through the walls into the room. and only the walls that are pointing to the sun are casting a shadow…
Does this mean that I have to create faces with two normals?
