Quote - Take a look at www.geekatplay.com/vuetutorialsnew.php  They have loads of tutorials for Vue.  These are the beginners ones and somewhere in the list is one about materials.

Thanks, Frank - been there and watched the beginner ones covering Materials.  As an example, I downloaded one of the JPGs, applied it to a terrain as a Color Map in the Material Editor along with as a Bump Map, and it looked, well - ayem, pretty awful. So - you see, I'm pretty convinced there's got to be more to it. and I must be missing something.
