I just started using Poser 5 sr3 and after hearing all the griping and complaining here I must say, it's actually not all that bad. As a matter of fact, plain Firefly renders look lotz better than my best P4 shtuff ever did with lots of work. My main concern with Poser 5 service paks and Poser 6 is memory management. I'm sorry but Poser 5 sr3 is still an absolutely lousy memory manager. Being able to make subfolders inside of the runtime folder and have infinite files = exquisite!! All the material room options = fantastic!! Raytrace rendering capability with other rendering options = a great step forward from previous releases. Having to constantly play the control-alt-delete song = SUCKS rawcore!! Memory management kills all other spectacular features of Poser 5. Please please please support better memory management. I love the user friendly interface and all the other features but it's like a tank being powered by a gerbil running on a wheel. I"m really looking forward to Poser 6!!! Lotza luv, finski
