how are you importing to C2? Facet mesh or vertex primitives? vertex primitive, with polymesh per material works best for me. I have some odd ways of exporting from Poser, I tend to 'group' my export by exporting my figures separately from the scene and combine them in Carrara. (keeping my scene as one object, therefore keeping the object list shorter) Making sure NEVER to export the world or floor, of course. Then making sure my options are unchecked for autoposition. (and making sure all my meshes are scaled up 2100 percent, as poser meshes are too small) never had a memory error, even with big scenes and even when I was on a P3 with 256 ram. (my computer is better now, of course)
