Some more Gaea stuff. Initially started as a tropical island, and finally ended as some sort of icelandic scenery. That's how it goes.
This is rendered with the path tracer (just because there is vegetation... looks so much better). It took twenty hours to render in 3K. Without water it may have taken only two and a half hours, I guess. Transparency is set to 0 in the water shader. I know, Ulco was mentioning not to use the water shader, but a plane with a reflective shader instead. I made some tests and found, that it doesn't make too much difference. And I really like the water shader's displacement.
The main factor for the long rendertimes in this case is as far as I can tell the viewing angle. It's quite flat and zoomed in as well, so there's a huge area of a mildly displaced and reflective surface, that has to be computed.
That's my theory. Maybe I'm completely wrong...
