I was looking at a book about volcanoes for a research paper, and in there was a very interesting picture. It was a crack in a very rugged, yet flat, area(imagine fake stones, if you will). Also, in the background were bigger hills. My questions are:
1) Is there a way to design a crack with functions or some other way? I don't know how to get the heightfield erode functions working, as none of them work for me.
2) Is there a way to get one area flat, like with a mask?
I'm not good with functions. I tried using them, but I never noticed a change.
Also, the crack is very smooth at the edges. If I can get a picture of it on my cellphone, I'll post it to show you guys, but that won't be until tomorrow. I hope you guys understand my description. :P

1) I'd think the simplest way to create a crack would be with a displacement map, not with function nodes. Make a black image with a white streak (or the other way around), load it in an image shader and apply that to the displacement input of your terrain (or some shader).
2) Flatten terrain - http://forums.planetside.co.uk/index.php?topic=2614.msg26126#msg26126 (http://forums.planetside.co.uk/index.php?topic=2614.msg26126#msg26126).
Thanks! I will go try those out. :D
Hey, good idea!
