The semi-parametric scene setup allows easy modification of the terrain. The relief is controlled by composite displacement map, the sand mask changes automatically by the displacement height. The scene is large-scale, but is not in real units.The scene uses Vray for rendering, but can be converted to any render engine. I put Standart material as Placeholder, so you can easily reassign the maps.The scene contains the light and render setup. What you see on images - is what you get.
