# Empty normal map after baking in cycles

I tried to make simple normal map, but if ray distance isn't 0 the final result isn't displayed correctly. If it is 0 things obviously are getting worse. The only difference between high and low poly meshes is lack of windows on low poly one. (windows are just little square extruded inside the mesh thingies)

• How are windows constructed? Is there any bevel / smoothed out angles or are all the angles between the faces 90 degrees? If they are then there's no information to bake into normal map, it doesn't see such information. – Mr Zak Aug 24 '18 at 19:32
