in case you're wondering exactly whats different well I posted this at simhq and thought I'd bring it here..
"mostly the rain is a slightly different color..the winds are changed,and the sky colors are different..as is the blending where the upper sky and horizon meet(gotta thank Dueces and TK for alot of help).I changed the night sky and changed the stars brightness.some were in teh weather ini file and others in the partical ini.thats why the new upgrade isn't anything but 2 ini files.
The clouds are the V2 atmosphere clouds,I'm working on more but they aren't ready yet.I'm working hard ot make the sky as real as possible..and I have to say the community has some very good people that have helped me a lot and TK has been great on answering all my questions. "
