First, what version of Poser are you using? If poser 7 and above, you could use the mat room for the light. Depends tho, on the way the building's materials are set up. Is there a separate glass mat for the windows? If so, you could use the Ambient setting in the material room. It's on Poser Surface. I don't know how to do the random effect but maybe some of the Poser Mat Room experts here can help or you could play around or experiment with it..

My bad should of responded to this instead of making a new message. I am using Poser Pro 2012.
