I needed Poser5's original P5NudeWoman.obj and matching blHipNoGen.obj as keys for the cute, Anime-ish AnAn R2 Run Time Encoded figure.
P5F was not in all P5 releases due to lack of space on the CDROM, so she and other extras were made available as an add-on pack from Content Paradise, downloadable upon entry of valid serial number.
The CP link is dead, but the pack was still available from SmithMicro...

I put in my P11Pro serial, got a '404: page not found'.
Support replied...
"Thank you for contacting Support. Poser 5 Legacy is not available for Poser 8 or later. This content was limited to Poser 5, Poser 6, and some versions of Poser 7."
I had a look on Amazon & eBay, found only Mac versions. Then I thought to try my un-opened P7, from when that Spring storm and a batch of bad drives dumped me out of CAD for a decade.
Surprise ! It was an acceptable serial !!
I duly down-loaded the P5, P6 & P7 packs. Note that P5F is only in the P5 pack...
Happily, these P5 OBJs were the correct versions to serve as AnAn R2's RTE keys. Young Aiko (A3) may now have an Anime-ish friend without A4's vast polygon count...
Although, IMHO, P5F is not as cute as Posette, she'll still be useful as a background character.
