"It seems there are some items, such as complex hair, that just won't work well with Poser 5 & maybe the Firefly, vs Poser renderer." This is actually pretty true. And for good reason. These hairs (developed by 3rd party content providers) are created using one of a few variations of method that takes advantage of flaws within the Poser 4 rendering engine to produce better results. In a very real sense, they are created specifically for Poser 4, using what is, in essence, a hack. Construction of hair in that same method for most other rendering engines today will produce similar issues in high end rendering engines. So, to not put too fine a point on it, yeah, you are absolutely correct: There is some hair that is not going to work well with firefly as is. It's not your puny computer. It's not Poser. It's not the maker of the hair. It is the eternal march of progress, squishing us all. Oh but for the days of carriages with horses! Hey, that gives me an idea for a pic. On the other hand, the Poser 4 renderer doesn't give you the precision of control over shading rates, alternative shading systems, light gels, and displacement, all of which can be used to create hair which is much lighter in resources (in other words, instead of a 1.3MB obj, you can use a 130KB obj, with the resulting difference in size for the cr2, as well), looks better (hey -- you can see the layers of the strands beneath strands -- and they cast shadows!), and renders faster with smaller texture maps. I'm fully in support of P5 -- well known fact, there. However, it is different -- not just from the standpoint of the user, but from the standpoint of the maker. Poser 6 will be out next year. I'm certain of that. When, no idea. But I am absolutely convinced that it will be out within the next 15 months. It won't offer significant new stuff, either, so Poser 5 and Poser 6 will co-exist fairly well, and there won't be much in the way of things which are different. So as folks become more comfy with this new program, you'll see the same sort of development for Poser 5 as we have seen for Poser 4/PP -- that is, hacks, which take advantage of the specific features of the software. The question isn't going to be P5 or P4 for new users. The question is going to be P5 now or P6 later for old users...
