Rhino Terrain

I just downloaded the new plugin for Rhino and love it. Great functionality for terrain generation that is often lacking in non-Architecture specific modeling programs. I don't have a ton of experience with it yet, but would like to know if any of you are aware of ways to apply images that are not georeferenced. Visual Nature Studios has the same great functionality for image mapping, but the need for georeferenced tif's made it a bit limited for proposed architectural projects.
