what does anyone need such an advanced sky system for ? Who is looking at the sky while playing their games ? Most people wont even notice any of the sky effects , and if they do , they'll just say , thats pretty koo , and never pay attention to it again . LOL , Why waste so much time and effort implementing a system no one is gone care about ?

Btw , all that stuff can be done with models , sprites , and scripting , but it seems like a lot of work for what it is , A good skycube is good enough IMO.
