This is essentially, the same render as the blanket version. However, I changed out the blanket for a shallow beach. The beach is a plane with a concrete shader. The tiling on the shader is multiple vertical but only 1 horizontal to get that banded look. This seemed to work pretty well. But, I'd like to get some actual sand type shaders for Iray. The whole idea on this render is to get that shallow shoreline look like the white sand beaches in North Carolina. There is some sky reflection and diffusion where the model enters the water.
