I'm gonna throw in on this one as well, and say that you still need Transposer.

Mainly for large scenes where memory overhead is critical.  When you import stuff using the Carrara importer, you are taking the bones and all the posing into Carrara which causes a lot of memory to be used.  It's the same thing when I try to pull DAZ Studio formatted files into Carrara as well.  I can get away with multiple V3/M3 figures with Transposer as the importer, whereas I'm lucky if I can get two done without memory allocation errors in a fully built scene. 

And for the record, the most characters I have pulled off in a scene are three V3's, an M3, and a Don, all fully clothed in the Mog Ruith interior, all handled through Transposer...
