If you are using Max 3.1, then BodyStudio is not an option since it only works with 4.2 and 5.x. The Habware plugins are max2obj and obj2max and are available at www.habware.at. They're free but they output a separate obj file for each frame. You can assemble them in Max but it is a real hassle. There is Maximum Pose II. They have a demo version but the commercial version is about $100. What it does is to convert the pz3 into a maxscript. The website is www.ev.ca/konan. I used the Poser Pro Pack plugin for a while with Max 2.5. I had the same problem but I was running on a Pentium II with 512 MB of memory. It seemed to crash more with the larger files. When I moved to Max 4.2, I got a faster machine with 512 MB of memory and it worked fine. It was still slow. Your machine should be adequate. How crowded is your hard disk? If mainframe memory is insufficient for applications, Windows uses disk space as memory. Also, I seem to recall some messages about Norton's antivirus being a problem there but it has been some time since I used the PPP plugin.
