Hi Al,

Sorry for the slow reply. I have been messing about with your excellent water texture.

I used the dielectric material I've used for water previously as the starting point for using the textures. After experimenting for a while I decided on both colour textures in the refraction channel plus bump. The normal map didn't seem to play well with the dielectric material so I left it out for the time being.

I would be very happy to have more like it if you don't mind doing them. Something to give a North Atlantic stormy look would be very nice.

Here are renders of HMAS Perth I with the unusual unfinished paint job she was wearing when lost, as well as Sydney rendered in KT with your water textures:
