Hi I have a question I was wonder someone could help with.
I am creating a sand dune simulation, and so far I am having fairly good results with displacement generated by maya’s built in water system to create smaller ripples / details on the dunes. In order to complete the effect, I need these ripples to appear only on one side of the dune (the wind facing side). If anyone had any thoughts on how to control the displacement effect based on the slope / direction of the sand dune I would be grateful if you shared that information:)
Thanks!
