Also- any serious modeler might want to consider the excellent Flight Simulator Clouds shown in this thread. The Free GMAX can be downloaded and used along with the really great Flight Simulator Cloud Texture Maps (of course these cannot be re-sold or freely re-distributed--- they are for reference only).

These maps can be recreated using PhotoShop, which is what I'm doing now- building my own clouds for personal use.
