And P5 figures with SDS have fewer polygons I have to correct this. All of the objects (including figures) in Poser use the same underlying description and technology. All the features such as polygon smoothing are therfore, in fact, available to both P5 and the millenium figures (I've always assumed but never checked that this is on by default for all figures). And, to be technically pedantic, SDS (subdivision smoothing) does not exist in P5. During the pre-release hype, some people became confused between this technology and the "micropolygon subdivision" technique that is the basis of the Firefly renderer as with all other renders that are based on REYES technology. This is a polygon (not mesh) level process and occurs towards the end of the rendering pipleline allowing subsampling, displacement mapping and smoothing. Now, the fact that those people who "became confused" about these technologies and patently didn't understand what was being implemented in P5 were actually the same people who were subsequently cited as the "Poser 5 Architects" when the product was actually released a few weeks later was, for me, one of the early indications that thing were seriously amiss. In answer to the original question, however, I still have to say, albeit with some reservation, that, if you have the money to burn and you don't specifically need ProPack's export features, I would still plump for P5 just for the additional functionality. There are a lot of problems still, but they are slowly getting addressed. Nevertheless, it's definitely worth keeping your P4 installation, since setting up complex scenes in P4 before transferring them to P5 for final rendering, saves a lot of frustration if your "pushing the envelope" in any way.
