Success! After opening the PZ3 in Poser 5 and resaving, it seemed to 'reset' everything so that Vue could understand it, including mesh directories and texture directories. So that's apparently my problem, if I'm gonna import a pz3 to Vue, I'll need to open Poser first and resave it. Not a big deal, since I usually tweak my PZ3's first before saving them. Thanks for all your help, people!
