I wanted to slice a height field into elevation zones, but the fixed band placement of the height splitter device wasn’t right. Using a bunch of height selectors, I got what I wanted, but I had to spend a bunch of time with a temporary setup of curves and combiners setting the threshold values and fuzziness/falloff so that the adjacent zones blended properly. It would be nice to have a version of height splitter where the interband thresholds were adjustable and you got add-to-one overlap automatically.
