I have used World Builder 2.2 and it is nothing less then awesome. I have tried to import obj files exported by Poser4, and have had about the same success I have had importing them to Bryce4, which isn't that good. Of course, I am no expert at any of this either. As for AWB2.2, the animations you can make can have things like individual blades of grass blowing in the wind, clouds moving across the sky, rivers flowing around rocks, and waves crashing on the shore. I only got to play with it for several hours, but what I produced in that time was unbelievable. I would like to buy version 3, but for a toy, it is sort of expensive. If you are a graphic artist by trade, you should try it out. I am sure you wouldn't regret it. I also do not work for them. My daughter goes to Kendall College of Art and Design and some of her friends use it.
