Coastline, intersection

[Artice-3d]

Hello guys, i'm still working on a project, so the next step is to create cliff intersection to create coastline stuff !!!   I know there are a coastline in powershader, but my cliffs doesn't work foe me, my terrain was created other way.. So maybe some tweaks or function to create such stuff  ) Thanks for any help   P.S.  Dune, thanks a lot for your help with clipping ))

One thing you can do is use an extra surface shader and set a minimum or maximum height and use the offset to lift or lower the ground. If you then add a mask, you can set the fractal by which this happens, and you might get some nice eroded shores.

You mean displacement stretch in horizontal way in certain attitude??!!  Yes it gives me what i want, but it stretches polygons so i can't add extra displacement detail because of that

I mean a vertical displacement.

But first somehow we need to make a horizontal coastline before to do a vertical displace

Yes, but that might be prohibited by the way you built this up. Perhaps you can use the mask for the high ground inversely to lower the low ground with a bit of color variation. But that depends on whether you used colors to displace, or the internal displacement. In the latter you can use the 'displacement to scalar' blue node to obtain a new mask, add a color adjust and set heights, then displace...

Dune you're a genius.. I found a solution based on your method with clipping, thank you very much.. When i finished i'll show the results of you valuable help )))
