Hi all,
I have been regenerating the scenery for US-Tennessee.
I've gotten to a good point to do an initial release.
See below if you would like to download the scenery or just want to keep track of the progress.

Be aware that I raised the level of detail substantially beyond that typical of World Scenery 2.0, so good hardware will offer the best experience.
If you give the scenery a try, I'd be interested to know what frame-rate you experience with your hardware. In the somewhat near future, I'll produce another version that is more frame-rate friendly, so I need a sense of how much to reduce the complexity.
