I'm not sure you exactly follow the discussion until now

It should be feasible to integrate orthoscenery with the water shader so there's "some form" of improvement. It's a case of adding orthotexture coords to water geometry, and swapping the current floor texture lookup(s) in the shader with the ortho-texture lookup. The othophoto code author Nathaniel Warner should know how to do that, if he has time. I thought this was where the discussion was at when I last checked the list.

What you'll get is some hint of a transition. The photo already contains water with a sky colour/sun&view angle/depth effect, and integrating it into the water effect will pile a bit more water with a different sky/angles/depth on top. It might look odd when there shouldn't be any blue in the scene - overcast/hazy days, low sun etc. The effects of a blue sky comes bundled with orthophoto images as they need mid-day/visibility. But this should more or less give a sense of transition in areas that don't have much already (like rivers, and river mouths), which is the big thing lacking until WS3.

If you are using a build of next for orthophoto scenery etc. try to use an older version of fgdata, or copy the following folders from an older FGData: Effects (water*.eff), Shaders (water*.frag), and data/Texture/Globe - the current water effect and texture formats are undergoing a bunch of changes, and will be construction site for a while like the Compositor was.

The water is slightly broken currently (and at the time of your posts) - it has bottomless depth/unported depth issues, due to some texture format changes, which is why those pictures of the water effect look like a uniform/flat deep blue.

See this forum topic for what the water effect normally looks like, and how it changes with overhead clouds:

This old, low settings, screenshot shows an older depth effect in action near islands:
