No. To be honest the new features don't turn me on as much as other people around here yet. Poser 4 seemed much simpler and easier to grasp. Although I know the new material room has potential, it was much easier just to add a texture map to a white model and be done with it. I would have perferred them to add more functionality to already existing Poser features like conforming clothes that will instantly conform to any body morphs used for the figures and a better lighting system would have been welcomed as well. Perhaps I just feel this way because of the learning curve involved with the new rooms, ask me again in 6 months and I may very well have changed my mind.
