""Render water surface" - renders surface of water in Rivers mode. Note that this surface is still opaque, to render transparent water surface you need to add additional layer of water and to use "Water depth" map to restore original river bed. I'll show later how to do it."
How is this done?

In short, you need to add additional spherical object having exactly the same position and size as main planet. Use Water depth map as opacity mask - this forces this sphere to be rendered only where real water is, this greatly improves render time. Use Surface layer with Water shader as child layer to render this sphere. You need to enable "Render water surface". To ged river bed you need to "restore" actual river bed by displacing flat water surface by "Water depth" map.

should work. In fact, this works, but with problems. This is why I delayed explanation - I hoped to figure what's wrong in this scheme. Sometimes where are multiple bright green sparks in the scene. I remember I created simple scene with simple river to upload here, but it was all in green sparks. It seems this depends on camera position and direction.
Here I attached other scene, in the most cases it is rendered ok, but sometimes the sparks are still there.
If someone finds what's wrong here, I'll be very grateful.
This scene is designed for 2048 resolution (my favorite resolution for rivers; higher resolution isn't needed usually if "Render HF details" is enabled"; but this scene can be loaded to free version - resolution is reset to 1024 then.

When is the complete classic erosion user manual coming?
I am still slowly working on it, please excuse me for long delay. For now please ask me without hesitation if something isn't clear - here in forum, via PM or email, I'll provide detail explanation, possibly with .tgd files.
