I agree. Color, bump and displacement for surface detail like grit and stone and dirt can be done as well in Vue as TG without bitmaps. That's what the above sample was about. However, the sculpting of the terrain itself is a different story in Vue than TG. I don't think you can get close to this particular TG render without using bitmaps or grayscales from World Machine or Geocontrol or TG itself. I think the underlying structure needs to be done in the terrain editor as opposed to mat displacement and then surface detail applied. In Vue, I think the ideal solution is a combination of bitmaps and procedurals. I doubt it can happen with procedurals alone. Just mho...
