There is soooo much you can do playing around with all these sliders! Remember though that to apply these effects to terrains independant of the rest of the scene, you have to have "Object-Standard" selected. Just play around with it all using two simple materiasl, and you'll get used to it. Then when you start mixing materials that are themselves already mixtures of other materials, you can really get some wild effects. Download bloodsong's "Whole Mountain" materiasl from the Vue Free Stuff here, for some really good examples of how it's done. They were made in Vue 3, but they work fine in Vue 4 too.
