Exporting seasurface normals as tiling bitmaps

[Steve Green]

Hi,

it would be handy to have a way to easily export the surface normals of a seasurface as a tiling bitmap.

You can render selected at the moment, but if you use choppiness the sea does not have a straight edge, so (as far as I can see) you have to have duplicate sea surfaces to fill the seam.

Thanks,

Steve
