Most of the new features in Poser 5 really are just other people's software attached to Poser4. The base program code is probably entirely the same. Really, there comes a time in every software's life, when it has to be rewritten from the ground up, to escape the drag of its own legacy. Lightwave, 3DSmax, Softimage, Maya, they all go through these phases. They try to make the easiest transitions they can, but ultimately they don't stop progressing to the next level. Poser5 was CL's rewrite wakeup call. ProPack was very obviously stretching the issue thin. Hair and cloth are all well and good, but not when you couple it to an aging basic figure rigging format. And for everyone that keeps saying "You can't have feature X in such a cheap program. And thats why we don't in Poser" are very wrong. There are plenty of cheap programs out there that have more advanced rendering, rigging etc for about the same price. What those programs lack is a method of figure content distribution that's as painless as Poser. What they spent that money on instead, is usually a full suite of modelling tools. So its really all about where those companies chose to spend the money, and not about features being too "complicated" "expensive" or "advanced" for a program like Poser. I mean if you rip the Morphing, Rigging, and Basic Rendering out of Maya and sell it on its own, how much is that worth without all the rest? Probably a lot less than the full package. ;)
