I'd opt for Poser 4/Pro Pack and Vue. I would go with P4 over P5 for reasons which I will not restate here but which have been adequately and fully stated by many. I have both Vue and Bryce. There are a few reasons I prefer Vue. It works very, very well with Poser 4 pz3 scenes. There have been times I have opted for a Poser 4/Vue scene over a Poser 4/Cinema 4 scene. I feel the Vue renderer is faster than Bryce. I prefer Vue atmospheres over Bryce, yet I agree that Bryce lighting is a bit more flexible especially for any interior work. Also, another advantage with with Vue is that you do not have the joy of having to deal with Corel, who happens to be in very dicey financial straits right now. Who knows where Bryce will end up? If anywhere. Do not under estimate the importance of this. Corel IS in very precarious shape, IMHO. My vote - Poser 4+Pro Pack+Vue. Take care, be well, keep flying. casamerica
