But that's what I don't understand, I've never had to "smooth" the V4 mesh ever when importing her into Vue, she always comes in as is without problems.

Maybe you could do some screen grabs of what you're ticking and not ticking when importing.

Is your Esprit version 9?

Does it have the 3 options for the Poser SDK, you may be using the wrong one, there is one of them that has what we used to call at the time, The "hulk" effect because it affected Poser tesxtures so badly, turned them green mostly, it could be this problem you're experiencing if that is the SDK that you are using.
