I would love to have the ambient light tied to a property. That would make it a piece of cake to write a nasal script to generate one or more properties to drive building lighting. The big win with this method is that you don't want the lights to turn right on, since that light is added to the ambient light in OGL resulting in a very bright building. You just want to make up the difference as the light fades. In real life, the light thrown on a building has very little effect until the ambient light gets very low and everyone's pupils open up to the point that they can detect the artificial light. OGL doesn't have that kind of range, so I have to play games to make it look right. Josh ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
