Hey Badger ... about the spires you mention, I might have ideas that may lead to a direction you have not thought of, but I am working on. Attached is a WIP of the first and second level of displacement for those rocks. Colours are ment to please me and may/will change in the final render.
Ulco: 2 years ago I did a silent restart for myself doing some too fancy stuff to be satisfied, but seeing that renders of those days were beyond my capabilities of my days.
I guess that I will/must stay with my no water/sky/vegetables renders for some time
Danny: I still like those Eff-Luxes, too
