One of my favorite parts of Bryce is the terrain editor, and I've done a lot of experiments in it, but your unique display has helped me visualise it in a new way! This is excellent! However, I think you can thank your lucky stars that DAZ hasn't yet utilized Bikermouse's Tiffer code for making 16bit heightmaps in the Terrain editor. 65 thousand-something levels of gray would be a lot more tedious to represent!
