Quote - DAle B how do you use the new features and how you suppose to make lighting.  Also how to with cloud layers.   Didnt we alreadhy have that.
  I am confused with whats suppose to be new. :)

Yes I can see a big improvement with rendering.  Especialy spectral atmospheres. :)

Just go to the drop down menu bar and select atmosphere; on the list you see add cloud layer, which brings up the editor pane and the libary of cloud types for the atmosphere you choose. Then just start adding and adjusting to suit.
