Yes, Dune, the birds are the Carrara seagull, it's an object. I use it often. There are actually 2 flocks here, I maybe should have left it at just one, they looked more together.
Martin: The terrain is a .ter I found around here somewhere, I think it's linked in the file sharing area, can't remember what it's called, I'm not at my own PC. I'm sure it starts with an 'S', if that's any help.
It's just that terrain, my default rock setup and finally my planetary grass shader. That's it.
