Ok so here is a snapshot.

As you can see, this is a physical node setup rather than cycles because the Principled BDSF didn't seem to go into how to do transparencies and liquid. (Aside from that, the guide was also unclear on how I would adapt a leaf texture set with the classic opacity/transparency maps.)

On a physical node I would have dialed down the opacity dial, plugged in all/most of the maps and possibly messed about with the scatter settings I barely get. Not terribly satisfying to be honest.

This one is the raindrops on Puddle from TextureCandotcom that I mentioned above. Only four maps with this one.

And lastly the Tidal Pools material from freepbrdotcom above. Since this is only partially transparent and there are no tr maps, this looked nothing like intended.
