Just a little more information on this one. If you wish to use transparency in conjunction with osgOcean you will have to disable the full screen effects (depth of field and cross hatch glare) as they overwrite the alpha channel of objects rendered within the scene. In order to use these effects at the same time as transparency you'll have to add another render pass for transparent objects and then combine it into the scene. If you want to add that functionality i'd be happy to add it...
