So I have designed a little map in blender but when I export the fbx (when selected in object mode) the model when dragged into the scene view appears half completed without materials. There is no floor and the tops of the walls are missing, Please help me fix this, Here is some pictures:
It looks like you have your normals backwards. Go to blender, select your object, go to edit mode, select all your faces, then press space, then type “Flip Normals”
