Reposing inside Vue is a waste of time, it can be done yes but it really isn't worth the hassle.
I have both Poser and Vue 7.4 open at the same time, if you repose inside Poser and resave it, Vue automatically sees the change and asks if you want to re-import it.
It also re-imports it to the same place in your scene, useful if you've moved it's position from the initial import.
This is  a much easier, quicker and better way of reposing if you need to.

Injustice will be avenged.
