Don't know how much money you want to spend, but I bought Vue Infinite and it imports Poser PZ3 and PZZ scenes in directly and flawlessly, no need to save it as an object file. All the materials are all there and even the hair transmaps are correct. As an added bonus, I can run Poser and Vue at the same time, and if I want to make a change in a pose, I change the pose in Poser and save it - and here comes the great part - Vue detects that I have resaved the scene in Poser and asks me if I want to re-import the scene, and if I do, it brings the PZ3 back in with the changes.
