John, I just say "WOW" ! Skymaxx Pro is bringing XP10 to a new level. Great piece of art and programming. I like the clouds, rays and the sky colours. The UI is superb to make changes on the fly. And frames are pretty here! For me there are just a few things left to be implemented, maybe: 1. Cloud shadows casting onto ground 2. Dynamic change in drawing distance of the clouds, referred to current XP Performance (maybe measured by FPS). So the lower the FPS are, cloud draw distance is lowered automatically. User can define the FPS barrier Once again, great work on this.
