Sorry that this topic has not been very active for a couple of weeks. One of the software programs I use to create RealScenery is produced by Laminar. A few weeks ago, a bug was found that didn't allow for two neighboring scenery areas to edge-match correctly to each other along their boundary. We managed to get this bug fixed, but then another very strange bug appeared where a hole to the center of the earth would appear near the junction of neighboring scenery areas. Now, I'm happy to report that this bug has been fixed, too, and we can move on with production. I now have a special build of the software and one that should be very robust going forward. I'm grateful to Laminar for taking the time to help me with this over the past few weeks. While waiting for Laminar to investigate these bugs and code the fixes, I started work on a much improved technique for smoothing/flattening the airport terrain. The current method used in RealScenery products works, but not as well, or as consistently, as I would like. I'm going to finish up the programs to smooth the airports, then re-run the scripts which generate the final scenery using the, hopefully, bug-free software. Thanks again for your patience!
