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
