Very cool, ArtPearl!

Its great we are discussing this here. Also its refreshing to have others participating in finding good solutions. As you said the function editor is wonderful (and powerful too). It allows you to really dig deep and come up with new or better solutions.

Sounds like you have quite a profound understanding of the function editor. That`s good to know...

Just checked out your positioning method and it works fine too. You`re right, defining a position instead of a distance makes sense.
What I also like about your version is that you do not have to "convert" the value for the texture map node, just change the sign.

Now we can go ahead and add a couple more heightfields :-)
