Ground debris is another story of course, but I still would like to try my hand at some of the shown sand structures (if time permits). Using some well taken photo's and derived displacement maps in combination with TG ground can be very nice, but only in front and sparsely used. I used the stone pop for some wood splinters and branches in some renders, in a bit of distance that works fine, but you can't populate huge areas, or you can have a holiday whilst populating.
Sand, huh...
