From my viewpoint, I bought Vue5 esprit and had nothing but trouble with it so after many discussions with their tech support I upgraded to Vue 5 Infinite and my own personal experience is that this has been much more stable and useable than esprit was!

 So if you do take the plunge go for Infinite!

You can import directly Poser pz3 files although I do believe it doesn't like dynamic hair but I've not tried it! I actually use and like poser more!

Injustice will be avenged.
