Thank you all!
QuoteYou can keep this foam, but add some new around the rocks.
That's what I planned and what I did.
Here's an iteration. Not sure if I'll go on with this one, maybe too populated with cliffs... Still thinking... But anyway the surfacing, or parts of it, will be ported to another project; I like it too much.

After that do some tests with a foreground patch of rocks so the camera has some solid ground to stand on.
Oh, almost forgot: I'm doing some tests with negative displacements.
