Practice makes perfect -- or at least closer to perfect. Two years ago when I started working with Bryce I relied heavily on Ray Dream to do most of my modeling. Then I would import everything into Bryce and render. Now I hardly use Ray Dream or Strata unless I have a very specific need. If you are on a PC, there are many free or very reasonable modelers out there. There are fewer for the Mac that are free or reasonable but they do exist. Personally, I think you can make some very nice dirigibles in Bryce by using primatives, terrains and symmetrical lattices. Sarah
