Its worth checking your system library>materials>water drop any of these onto any model. If you find a water preset (preset folder) pop that in your scene then drag a material onto that, press play and you should have some moving water. The action on the plane can be used on any shape even sphere which can look great.

As for the water plane as what @Sage1969 was talking about is very much doable without animated textures already.
The PBR material has the diffuse, normal roughness etc.. but also 4 detail layers with both diffuse and normal, all textures have their own uv modifications of offset, scroll and scaling, which all used together with different normalmaps can produce some very interesting results when it comes to water. As mentioned before, the only thing that is missing is some form of volume for underwater(mix of post fx and camera trickery) and vertex movement for the surface of the water.
All the opacity and and alpha is taken care of. As for edge depth transparency, this is a bit more special case as it requires a unique depth buffer to be passed into the material. We did this with the new ocean system on an older dev version(still unreleased lol) before shaders were being upgraded.
When I come to the water shaders again which should be next few weeks if I'm lucky, I can take a look then and see how we can go about trying to support everyone's water wishes lol
edit: Starfire got there before me

We do have to water plane which can be applied to any mesh shape and size. This contains a vertex section to create the waves and the standard material with normals on multiple detail layers. This can produce an animated water.
In the V2 we have removed the water plane in favour of the new ocean shader which looks nice at the edges with depth blending.
You will still be able to add a water material which will emulate the refractive / reflective surface distortion. Boyancy can be created with the physics and a little script.
Our current aim is to be able to populate big game worlds with awesome lighting, the water is a nice bit of eye candy but unless the game was heavily ocean / surface water centric most ocean systems look great.
Now water we would like Nvidia water system oh yeah!

But my point was not about S2, per se, but about the water it uses (ocean, rivers, and lakes). If the developers of Skyline can learn something from it, then why shouldn't they have a look? There are some unique ideas in the engine that could be made better in an engine like Skyline.

I like that I can ask here and it is answered or addressed. There are base tutorials that exist so you can work the basics of development right way and for me the learning curve was more of a straightaway, which is always a good thing.
I do agree on the need for a water plane. Could that surface not just be an animated texture you assign to your model (cup, bowl or well) with the material editor? I did a coffee cup that way. It is the easiest to guarantee the shape you want/need. I just needed the cup to look like it had coffee in it though I did not need it to scroll or anything.
I also did some work with a waterfall and stream head in a similar way. The waterfall looked a little questionable the stream head was fine (with lots of scroll direction adjustments). I admit that a pre made plane will increase ease for the developer though you can still do a lot now manually. So far my only limitations have been how much work and time do I want to put in.
ie.. the water fall had something like 35 plains to make it look almost acceptable to me. Just add particle for mist at base and you could be off to the races rather quickly.
Just suggesting to maybe look into, not saying how you should do it!
