Quote - Can you tell me more about using the script in P6.

P6 introduced compressed geometry (OBZ) files.
The supplied figures have these instead of OBJ files.

To uncompress these, you can either use the supplied script (Windows menu | "Python Scripts", then on the script pallete, "Utility Funcs" | "UnCompress Files"), or use something like WinZip  or 7Zip.
You may have to change the extension to GZ, if your chosen program isn't recognising the files as an archive.
There is also a program in the FreeStuff (by kawacki if IIRC), and ISTR at least one python script (check the Python and Poser forums).

As you only need to unpack the OBZ files to OBJ, I'd try that if you don't get anywhere with one of the other methods.
