qwerty, thank you very much 
justin1278, nice to see that you’re into this as well now! 
I wouldn’t say that the 5.5 version is easier than the earlier ones, as I tried a demo of Bryce 2 back in the late 1990’s (it may have been 1998 or so). It was almost identical to this one, at least the interface. Now of course, new functions have been added, and better rendering. If you’ve already tried 5.0 I guess you have a clue how it works.
There are tons of great tutorials on the net, but I would gladly give you tips! I just don’t know where to start, there are so many kinds of things you can do. Three things I used for the latest picture:
The Sky Lab. You find it by clicking the text “Sky & Fog”, then the little cloud with a ring - just to the right. You can also just press Ctrl+K.
The Terrain Editor. You’ve probably seen it, just select a terrain you’ve created, and click the little “E”. Here you can do anything to create altitudes! I used a feature to improve the resolution; on the narrow and high dock in the upper left corner, there’s a square/grid. Chose something better than 512, I had 2048.
The Materials Lab. It’s a great feature to change the scale of the materials you put on your object. This is made from the box in the upper right corner; you’ll probably see three thumbnails of textures, and maybe the text “World Space”. From here you can change the material in many ways.
Let me know if you need some sceen posts to find these things, or other tips!
Btw, here are some great plants, grass (which I had in my scene) and stuff!

EDIT: I was curious to compress the br5 file (the scene) with 7-Zip’s 7Z format. It went from 54 MB to 5.9 MB!!!
