I've got a great book, Real World Bryce 4, and it states that I should be able to restrict part of the Terrain Canvas subject to editing by using the clipping bracket. Despite my best efforts, any changes made to the terrain while clipped are still being applied to the entire terrain when unclipped. I'm using both the clipping bracket and the gradient tool in different combinations, together and alone, and am also working from both the top and bottom, but the result always seems to be the same, the effect is applied to the entire terrain. My idea is to create an island which would have smooth beaches around the edges, and rougher texture higher up. I'm sure I'm missing something simple, but can't figure it out. Suggestions, please???
