with maxwell sea we can't add uv set ; scatter ; grass ;
if it is possible that we can convert the sea to mesh

Can you post-process it out of an orthographic z-depth render of a camera looking down?

I think z camera distance is usually stored as a function of 1/z so that infinitely far equals 0.

Actually, I think it would be really cool if we would have this feature to "export" or convert Maxwell's modifiers to mesh or to something which we can work with afterwards.
I know it would be very dense object, and data probably would be fairly heavy, but I guess sometimes it worth it.

So it would become some sort of "modeling tools". Which could be very useful.
Like something everyone wish to have is export displaced mesh (after displacement of course) say, for use in 3D printer for instance
