Thanks Chris for taking your time to answer my question. That gave me a better understanding of openscenery. Unfortunately, I have a few custom scenery errors that have recently showed up since I converted over to x-plane 10. Even though I am tempted to zip up the airport scenery and send to you, if I don't figure out how to do it, I won't be able to solve my other scenery issues. I understand what you said that there is not object called "objects/furniture/lights". Is there a way to delete just that "object/furniture/lights" reference using openscenery or is it required to use WED? Unfortunately, I have never used that program. My goal is to just remove the error from popping up in xplane 10 by eliminating this line. Thanks again for your help. John
