I just looked at it real quickly, but it seems as though all that's happening is the material is being converted to an image file? Vue does that too-- one of the terrain export features. As would be expected though, though you can export a Vue terrain with it's material converted to .bmp and import that into Bryce, even with the texture automatically applied, it loses al it's more important features, such as altitude-dependence, etc.... I assume that Bryce materials would act the same in Vue?
