Hey everyone, just having an issue that I haven't been able to work out a solution for, hoping someone here can help! I'm attempting to recreate the effects of the Ramp device in World Machine, as I'm very curious to see how it reacts in 3 dimensions. Essentially, it mirrors a curve some number of times (determined by settings), which can create some interesting patterns that I find incredibly useful, especially in texturing. I've worked out a way to recreate a Ramp device with a frequency of 2 in World Machine, but am having a difficult time figuring out how to translate that into Terragen. The workflow I've made in World Machine goes:
1) Clamp input terrain to 1/2 maximum height (I've found it easiest to clamp the lower values to 0)
2) Using Select Height device, use the clamped values to generate a mask
2a) If clamping lower values to 0, invert the generated mask
3) Route the initial (unclamped) terrain into an Invert device, masked by the results of the previous step(s)
The same effect can also be achieved much simpler by manually drawing a curve, but I've noticed that Terragen doesn't have a curve node (at least, not that I've been able to find), so I tried to go about it in a way that I think could translate to Terragen. I have a feeling that, if this is even possible in the first place, the secret lies with Function nodes, but I'm not sure if I'm just not understanding them correctly and using them wrong as a result, or if there's something else going on. All I've managed to do so far is accidentally create a bunch of terrains that make zero physical sense (Such as infinitely tall pillars, or seemingly inside-out spheres). Any help or insight anyone can provide would be greatly appreciated!
