Thats indeed the tutorial Im referring to. Im sure its a great tutorial for those who have a basic understanding of the function editor, but I dont have even that. Plus I use Vue 5 Esprit, and not Infinite. I have a feeling that the Infinite version has still more possibilities. Your example of a foamy shoreline is great, but I cant seem to use it in Esprit. How can I get the "distance to object below" command, for example? And I would especially like to learn more about functions for procedural terrains. I have a feeling that some really stunning terrains can be created with the function editor, but I lack even the basic knowledge to get going. I dont have the insight to learn it from scratch. Or perhaps more honestly, I dont have the patience...
