Yes, that is, you will use your standard Vue water plane and its materials, but you do need to apply some a sand-like material or a sand picture to the beach plane. I've attached a small clip out of a photo of sand I shot this morning. Use the material editor for the beach plane to "Load A Picture" onto the object. (Consult your User Guide.) You may need to halve the tiling resolution of this picture once its applied to the beach plane to spread it evenly over the plane and make it look right. make sure that you've tilted the beach plane down toward the water so that it dips under the water plane.
