Title: Run Aground

Nemo's miscalculated a bit and run aground on a sand bar. Have to wait for high tide.

Plants - Xfrog
Nautilus - Ogre

Fun! Looks good too. Did you build the ship?

Sorry, I hoped the model credit was made clear in the first post.
The model was made by Ogre and thanks for his generosity.

This render took about 24 hours. Detail 9, AA 8 , GI 3,4.    It does not do its final wrap up promptly.
As some others have reported, this render goes into a "not responding" state for
about 15 minutes after the last bucket is completely posted to the screen. ( in this case it's a bucket of water  :))
I don't know what is going on, but
I did watch the memory usage of the Terragen process go from 2.8 gig to nearly 4 gig in that 15 minutes and
then in the final seconds memory use goes back to about 1.6 gig.
Though it may not be apparent there are a
lot of plants populated. The start up populating takes nearly an hour as I have a lot of ground cover.

24 hours... that's a long time for this size , fleetwood. The result is really nice, though! I like the rocks as well as the subtle voronoi lighting of the bottom of the sea. But maybe with less detail and AA the result might have been quite similar and much faster. Did you try that? And where are all the plants? I only see some trees. The distant greenery may be easier/faster to do procedurally?
But; great image!!

Thanks,
My machine is previous generation, Intel  Q6600. It is slow by today's standards, and I chose
high cloud quality in 4 layers plus such a large area of water.

You're right, of course, about the plants. Mostly they are showing only as distant shades of somewhat green.
That should be my next project to learn about getting good distant vegetation effects procedurally.

Fake stones can be used for distant trees and shrub.

I like this composition very much. A touch using the painted shader getting vegetation where you want it should be an easy task.

Thanks, choronr about the painted shader.

If I see what you mean,  defining the areas of plants with painted shaders would  reduce the amount of work
the Terragen populating routine finally has to do. The way it is, if I forget and close Terragen, it is an automatic
hour added to generate the pops, just to do a test.

I guess I need to scrap the easy but slow overkill approach blanketing big areas with small plants.
