Now Pro users can load their .ls4 file into an existing scene. After selecting a file a new dialog let you choose to import light, models, imports or any combination of them. My favorite new feature is that lights now have an extra setting which makes them turn on automatically at night and can even be randomized so they do not turn on all at once. All you have to do is animate the sun position to create a nice effect for night scenes when this new feature is active. Now glossy surfaces are drawn with improved quality by removing errors and improving the filtering of the reflections. You can even create artistic images by enlarging the moon. In Lumion 4.5 you can directly control the size of the moon with a movie or photo effect.
