WIP: advanced "sandy waves" surface texture macro

I have tried to do my research on dune formation and the associated processes, types and so on with the idea of bringing some of it into world machine.

The goal currently is to create a macro suite that would allow for output of many hires seamless textures for use as detail layers on levels containing desert ergs/plains or sandy coastline areas.

The macro I’m working on at the moment uses 3 wind sources with a slipface running parallel to the dominant wind source. Here is the first screen cap as I am looking at it now.
