I am assuming that you want just a single frame from a Poser "clothifying" session. I've never been able to work comfortably with Vue's animation (not enough practise), so I go about it from the "other end"....

In Poser, create and collapse an animation:

1. Create dynamic animation. (I always try to have extra frames after the end of the posing to allow the cloth to settle. Sometimes needed, sometimes not, but usually better to have the choice.)
2. Move to the "best" frame of the animation and export just the cloth as a .obj - no options set except possibly "existing groups" for texturing purposes. This is the only way I know of saving "posed" clothing as a single entity.
3. In the Animation Editor grab the whole of that same frame and move it back to frame #1. Delete the remaining frames (leaving just a single frame).
4. Delete the clothing then import the saved .obj (again, no option set - especially ensure "% of figure size" cleared.
5. Save the scene (as a new .pz3 file).

After the above you should end up with a single frame which has both the pose you wanted and the clothing that fits that pose.
Edited to add: The export/import route will lose any special Materials applied to the clothing, including transparancy values. Either re-apply them before saving the single frame, or re-do the materials in Vue (probably better). This is one of the reasons for saving the groups when exporting ...

In Vue:

1. Import that single frame. Actually, since it's a single frame, you won't have the option of setting a frame number anyway.
2. errrmmm... there is no 2.

I have Poser 5/6 and V5I. It works with those, so should work with later versions..

Hope that helps,

Cheers,
