Just playing with the future V9 (version 9) of the weather system. I offer already the EEP addon on it but the sunrise and sunset has always the same time (6am/6pm). On this version, sun elevation will follow exactly as RL (not 100% but close as I divided sun elevation in 22 bands using 320 EEP skies in total. Had to set some few fixed values for azimuth but what gives the day or night lenght is the sun elevation. so.. just doing some tests and its working so far..

Working also on a Wolf Territories version with the Wolfviewer/wolfstorm as it would work only here (so its deployed to work with customized lsl scripts from grid, so one no longer would need use/rez the sculpts for the rain/snow. it comes from the viewer. Will post it here when I`m done.
