I picked up V4 in the last minutes of the closeout sale, and I'm having a great time with it. I'm amazed that there is effectively no documentation on using it. In fact, the manual was buried in the download zip and did not install to the working directory. It took a tech support call to find it. Oh well. My question: Can someone point me to a tutorial that discusses how to blend the junction between two terrains? I don't have the image here, but I can describe it: a forested island terrain embedded in a beach terrain and all surrounded by water. The water/sand junction is hard-edged, which is fine (though a wet perimeter would be nice...), but so is the edge where the foliage on the mountain meets the beach. In 2D, the fix would be feathering. I don't suppose it's called that in 3D, but there must be a way to do it. Please, not in postwork. Any ideas would be helpful. Thanks, Mick
