thanks for reply.
hmmm, I tried with voronoi+ but did not get the desired results.
IceFlow seems to produce only flat-ish ice-shelfs, but no "broken off, steep cliff walls".
I remember, there was a node in Geoglyp (addon for world machine) that looked like square-ish steps
, varying in height. But could not find something similar in Gaea atm.
maybe you can give some more advice on this, please?
