Thank you. Yes indeed the colors of the leaves could need a little variance. I
will look into that. The sea could be a little bit more blue. But I failed so
far to accomplish this. (I used an old material I found here at the newsgroups
and tweaked it a little bit: TdG_NorthSeaWater. I think you know who authored
this...). My main problerm is the flow itself. But it seems that I will have a
next picture within some hours. Now I abandoned the idea of several media
statements and joined all ten cloud elements into one df3-file. The result is
not the picture I intended but the best compromise I could find. Having more
than one media statement into a box seems to yield more complex interactions
than described in the POV documentation. It is not simply having a "union" with
more than one media statement or having a "difference" with more than one
density statements within a media, it is something between. I took a lot of work
to have my parts of the clouds fine (and a lot of rendering time) but putting
them together I found parts wiped out completelly and other parts "amplified" in
a way. Even the picture which will came up the next hours (hm, may be tomorrow
morning since it's slowing down actually) has a lot of parts of the original
df3-file missing.

Tomorrow I will take a break from this image. I would like to see a family of
rubber ducks around some lotus plants...
Best regards,
Michael

LOL I know that feeling.
The landscape is looking great.

Yes, and sometimes one has to enjoy life ;-) Borrowed a lot from Gill and
eMirage (lily from eMirage (BlendSwap), water and rubber duck from Gill Tran)
here is a first wip.

Best regards,
Michael

In these days of hot weather, this is exactly what we need :-)

Well composed and executed. But I hope that the pond is nowhere near 
your volcano. ;-)

Makes me want to jump right into my display.

"Rubber Ducky, you're the one
You make bath time lots of fun
Rubber Ducky, I'm awfully fond of you.

Every day when I make my way to my tubby
I find a little fellow who's cute and yellow and chubby
Rub-a-dub dubby."

If the pond is to the south east, it is safe. None of my five simulations run
into this direction. But one shall not trust them in RL.

The pool was by Gill Tran. My vulcano is still running since I decided to start
over again. Seems I mixed up some things working on more than one machine. But
first results yield old problems. It is running now with +wt6 to give me some
performance for other issues. At the moment I'm at a day rendering time with
that.

Fortunatelly the ducks are rendering faster. And I changed the one or other
thing here. First I removed Gills Water and replaced it by an own water
isosurface I created after the advices of Chris Hormanns water tutorial I read
some years ago.

Second I switched to a HDRI lighting using Jaimes patio.hdr.

Third I replaced Gill's rubber ducks by my own, but at the moment I still use
Gill's textures for them. An afternoon with Wings...

This will be the last WIP of this interim image. I only will think a bit about
the textures of the little beasts and add some focal blur for the final.

May be I will have one of them wearing sun glasses.

But this one was a lot fun.

Best regards,
Michael

One of two final alternatives. This has some obvious flaws especially to the
left. In some areas I got more density but in other areas I lost density
completely. The other one will come within the evening. Rendering time was more
than 4 days, so revisions are not possible.

Best regards,
Michael
