Hi, I'm very new to Bryce and I want to create a river. I can see that I could make one by putting terrain objects over the entire landscape and make sure the lowest points form a long, winding area, then add a water plane. However, that sounds tedious and difficult, plus I wouldn't be able to have it flow down a mountain.
Then I got a suggestion to use metaballs: put them half-submerged where I want the river and give them a water texture and make them positive, Boolean-wise. Then put a large rectangle over them at ground level, make it negative, and group them all. But I found there's no water inside the metaballs, so to speak, just the gray stuff. So that didn't work, unless I'm doing it wrong. Help! Thanks, Willow
