in my case, it can only import P7 pz3 files consisting of primitives or early characters (p4woman) which don't have obz files located outside the geometries folder. tried to import jessi.pz3 and all I got was the skullcap. tried to import miki.pz3: caused carrara to crash. sydney.pz3 came in empty. I think I've got transposer, just didn't install it, but then they're saying it doesn't work with P7. the main thing it can do (in my case) is import runtimes into content tab and open cr2 files from said runtimes.
