The real answer is 'It depends'. Things like textures and transmaps -should- import from Poser to Vue with not problem, as Vue has the best out of the box interconnectivity with Poser.

However.

The first gotcha to be aware of the the pathing. Poser does a recursive search if it doesn't find a resource where its supposed to be, or if the path is incomplete. External programs don't have access, so they depend on all the pathing information to be explicit. If the pathways listed in the CR2 (or PP2 for props) are accurate, that won't be an issue.

You -might- have to tweak the imported textures; poser and vue implement some features differently. Not a hideous difference.....more along the lines of what Poser considers transparent vue considers opaque. Off the top of my head I don't remember what particular features need tweaking, but it is almost all literally moving a slider from one extreme to the other.

If your system can run them both, then once you get things set up, you should have no problem importing a pz3 scene file into Vue.
