Can anyone help explain why I'm getting the dark splotches in the sand areas of this render? They appear to be shadows of some kind? They do not appear in the preview window.
Looks like a displacement intersection issue. What if you vary those values (if that's the case)?
Thanks, I'll give it a try.
This has given me some problems too over time, and the trouble is you can't see this happening in the preview, only when rendering.
I sometimes run into strange artifacts too. I think the only way to find out what's causing it, is to disable clouds, textures etc. one by one and do small test renders of that area until it disappears.
I have tried everything I can think off. I would appreciate a second or third pair of eyes. Attached is the Scene File. The heighfield file can be found: https://drive.google.com/open?id=1g-4fWfeTBiSCoDJFWk1Pb1_DOAVqSJS8
OOPS!
Also it is frame 270.
The rock textures will be missing and I have deleted all of the populations.
This is just the default vanilla scene, can you re-upload please.
Sand ripples are excellent well done

Sand ripples were downloaded from a thread here. Sorry but I cant remember from whom I borrowed them.

It's very frustrating.
You have "Lock subdiv to frame" enabled with frame 1 selected. You have a very large camera move and with terrain geometry dependent on detail calculated at frame 1 (and Level of Detail being dependent on distance from camera), you are ending up with very low resolution geometry in the foreground. Disabling the Lock Sudiv option resolves the problem. If you did not enable that option to troubleshoot/resolve a specific issue we recommend not using it. It's really just there to deal with a few problem cases that are not otherwise easily handled.

I saw that you have a displacement intersection indeed, but am tied up today and tomorrow by a very tight deadline, so I hope someone else will have an indepth look.
