This is the cleaned up version without the obsolete nodes, non-native objects and references to images used for masking purposes.
Inside the project you'll find some notes with what I think is essential information on understanding how the set-up works. [attachimg=3]The Detail render shows the impact of changing the "Gradient patch size" from 5 to 255 in one of the 'Floating Islands'.
Have fun playing with this one!
