Repeating the processing scheme ripple

Most of the water rendering, due to the use of a normal map Wrap, resulting in long-range observation watermarks, have a greater sense of repetition
that we can use normal maps 2+ sheets, plus a mask diagram (4 channels ), by sampling lerp mask map, and then choose which one to use normal maps
this mask drawing as large as possible, so remote rendering out of the water, repeat sense than the end of
fact, the above methods, the use of a huge normal map can also achieve the target.
