Isn't there an automatic detection in Vue that an imported/loaded item has changed? I think so. It definitely is for Poser imports - but for obj or 3DS I had this too.

What Vue version do you use?

AND, isn't there a demo version of Poser so that you can try yourself?

Last but not least, with Poser and its ps3 import you can use DBurdicks SkinVue Python script which is a big improvement of the workflow as well.
