Mark. To get to Elevation, I guess you have to insert Terrain Distribution>Custom?

I just can not work out where on the shader list (See previous print screen)  to actually place this--and then, looking at the things to adjust seems rather daunting to know what to actually set!

(I am enthralled by Enhance C but the complexity of using is pretty daunting--NOW that might be  a tutorial CD idea that I might buy?---AFTER you fix MY problems!!!!!)
