We start with the Camera Facing Billboard "Band of Clouds" This forms the primary backdrop and saves having to construct HUGE AMOUNTS of Cloud GROUPS in the scene.

BTW- Everything you see in this little Cloud Tutorial can be
done with VUE 4 and VUE 5- as well as V5 Infinite. I'm not
using the ECO-CLOUDS at all here. So this should work for
everybody out there. The nice thing of course for V5 and V5I
users are the Camera Facing Billboards. That's a big time saving tool when you are moving your camera around and knowing that your clouds are following you around like baby ducks!
