I recently wondered about this too because I find that the terrain materials in Vue are not as "rich" as some of the Bryce mats. For instance, in Bryce I have a terrain material that is sandy at the base of the terrain and gets rocky and grassy as the terrain altitude moves up. It's great for islands. A sandy shore and then a mountain. The base materials in Vue don't seem to have one with a similar effect and my attempts at creating one have failed. The only thing I've thought I could do is have a separate sandy shore flat-ish terrain and then a mountain terrain each separately textured - but Must I? I will try the Bryce export method and see if I get "satisfaction". Dave
