I have critized P6 rather hardly in former posts, but meanwhile i like it more and more, even if the bugs are still there. But i have rather complicated scenes, a lot of figures, background stuff, lights, and i think that people who are doing more portrait- and single figure pictures will rarely run into the memory bug. Furthermore it seems to me, that P6 works much better with scenes build up from the scratch in P6, but with scenes imported from P5. Another point: to work with P5 and P6 without too much frustration you should carefully read the manual-chapter or tutorials about the render-settings. Things like the 'minimum shader rate', 'pixel-samples' and so on have an enourmous effects on quality, speed an stability of the firefly-renderer. And there is a third thing: many characters like V3 use rather dirty tricks to 'abuse' the poser-data-structure in a way, that most likely wasn't planned from the developpers (or maybe planned, but then stopped, because they recognized that alle those inner morph-chains were too buggy). It must be a hell for the programmers to look for bugs in structures, that they would like to throw to the garbage, only to keep the very popular products from a competitor alive ;-)
