I’ve been pondering a workflow that would do a geological simulation to generate a bunch of mask maps before launching into WM. It would be handy to have a sedimentation device that could lay down ocean floor or volcanic ash layers. Layer thickness controlled either by a mean thickness parameter or by a thickness guide map.
I want to fill in low areas without eroding the high areas, so the erosion devices aren’t ideal for this. I’ve got a macro that approximates the desired behavior by doing some arithmetic and a “max” on an input terrain heightfield and guide map, so this is a low priority.
