I basically have a floor and a ceiling made from the standad square prop and walls with windows in them (Joe's Window Walls) I have a spotlight shining straight in the window which cast shadows through the window and on to the floor. Works perfectly. How ever there is a big chunk of light where the floor meets the wall almost like it is seeping through (Like light showing under a door). I have raised the floor so it well over laps the wall but its still happening. Any ideas? :) Thanks!
