I plugged a powerfractal into two twist and shears with opposite values and merged them, except I used the original power fractal again as the control node. It was a nice terrain, it twisted one way on the low sections, and the other on the high sections. It would probably render faster if I cloned the power fractal and removed a lot of the octaves from it and then used it to control the merge shader, but it works and looks pretty. I love the idea of subtracting the terrains, that's a stroke of brilliance, what gave you the idea of doing that?
