I have been looking for a terrain building program myself, so last month I downloaded the demos for all three. Each of them can import Poser models and each of them creates a truly beautiful end result. In the end I chose WorldBuilder. I am also a 3D Studio Max user and WorldBuilder has a better interface with Max. Though Worldbuilder is not as easy to learn as Bryce or Vue, it is not in my opinion overly difficult (compared to Max). It also seems to be a more powerful program. Granted, I am new to Poser and only used the demos for these programs. Perhaps someone with more experience will answer your post. Jay
