Drag the subcontours button to the left 0n your duplicated terrain and I think you get the effect he was going for maybe? You then have to shorten the y axis a tad .. and I did rotate the whole terrain ever so slightly .. but in general I managed to get the effect.. oh I also increased the resolution and made the terrain solid before I duplicated it. My self I am afraid I found the tut very confusing overall.. I gleamed the general idea but I think to get the most out of this you REALLY have to understand the DTE and how materials , textures and components interact .. the whole thing gives me a huge headache ;-)
