Once Poser 5 for mac is out, I honest still see myself rendering in Cinema 4D. I have a G4 800Mhz 512MB RAM and I don't run into much trouble rendering in cinema. Poser on the other hand.. yikes. I give it everything I've got and a few large textures makes it crap out telling me it can't find the texture files, and leaving me with all-white figures. it sounds like P5 is not going to be much of an improvement over P4 efficiency-wise, but I hope OS X memory manangement works in its favor. -Adam
