Re: Windows do not cast a shadow

@montrealwizzy Windows are working properly in my game.  Keep in mind that the time of day and positioning of windows has a lot to do in determining whether light streams through them strongly enough to create patterns on the floor.  Have you already tried viewing the room at different times of the day?  You can also try rotating its position.  You should be able to see light streaming through from at least one side of the house.  From your image, you didn't have any windows at one end, and perhaps that was the direction from which light would have streamed. 

If you aren't getting light streaming in from any direction no matter what you do, please try the following steps: 1) Remove all mods/CC, 2) clear your cache, 3) repair the game via Origin, 4) start a new save, and 5) test the windows in the new save.  You should also make sure that your graphics drivers are fully up to date.  If none of the above helps, please let us know.
