V4P main purpose is to offer Vue4 features to the professional artists. It allows the ability to communicate with other programs like Lightwave, Maya and others. Many professional artists and animators want to use the outstanding atmosphere that Vue can provide and V4P gives them this opportunity. That is why V4PRO is called PRO I think and has the extended export functions, and G-buffer render capability. Those features are a very big help to the professional artist. It would be up to the individual user that has Vue as their main 3D application to decide if the improved render qualities and faster render speeds are worth the investment. To me it is. :O) `shoop
