As the title suggests. How would one go about this? I tried get alt, surface layer with terrain as child with maximum alt, and with a surface layer as a mask with maximum alt and solid white colour. None of these even effect the terrain or cut if off at the desired altitude. I even tried offsetting by "crunching" the tops with a minimum alt but wasn't getting right results.
Been trying to make plateau type scenery using just PFs as the shapes provided are often very nice compared to warping/fractalizing a SSS imo, but can't grasp how to get my tops right, being mainly just flat, but some curve to the ledges.
is this what you mean?

was playing with soft maximum / minimum a while ago and got this.
play with the "softness" node to round / harden the edges
Of course! Duh! I love my Disp to Scalar! Thanks a lot digitalguru, who knows how long until that dawned on me. >.<
I have just found out with some testing that this can be used rather reliably with high Noise Variation on a noise flavor like Voronoi Billows to create canyons, that are both floored, and ceiling-ed.
