The details of this process are outlined in the Bryce manual. They were copied four times and rotated around in a circle to create the final tree. You can download it by clicking on the picture to the right. I was happy with this scene for awhile until I decided that I wanted something more dramatic. I decided that what it was lacking was a good sky.
Skies are a crucial element in a landscape.
I created a three layered sky. The first layer was one of the preset skys that comes with Bryce. To that I added two infinite planes of clouds to create the final striking result. My final step was to position the camera in a place that I liked. I ended up changing the orientation of the image and widening the field of view so that more of the sky was shown.
