Nope, you did nothing wrong ;)
that's the problem I'm talking about.

Vue has a special importer, to convert .pz3 files to normal scales.
But Poser ITSELF, internally, uses a bloody mad set of TWO scales.
It's "displaying" things based of a 1 Standard FIgure height  = 8' high (approximately)
But the obj models themselves are at a TINY scale...it's magnifying them for display and render,sort of

Your importer thinks it should be scaled to metre, feet or whatever and shows that, so it's totally barmy, ain't it? ;)
