With all due respect, I'm not sure I buy that you could have up to 8 characters, unless the textures are low-res. I'm not saying you didn't do it, but I can't get Poser to do more than 2 or 3 with high res textures even at 1024 or lower settings. Transmapped hair generates a lot of memory too, as do some props or characters. And I have a fast machine (2.5 Ghz Athlon XP, 2G ram @ PC3200). Poser 6 only lets you set the max memory usage in the preference settings to 1G. If you go higher, it thinks you have NEGATIVE memory, and nothing will render. Sorry, but I'm so frustrated with Firefly. I think the should get rid of it in the release.
