Y'know- I did a christmas animation with Poser 4 and was getting 12 sec/frame 720x480 on a P4/2Ghz 512Mb RAM. It was going to take forever. I blew the money, downloaded the Poser Pro Pack then rendered in 3D Studio MAX and got 2 to 4 sec/frame render times. - and got better output to boot. Batch rendering worked just fine with Windows XP home edition and I'm still using MAX 3.1... I just set it to batch render, went to bed and everything was ready for After Effects when I woke up :)
