I don't have the supermodel Vicki, or else I would have a look at her geometry , but I do know that over-morphing can cause problems at the polygon level. I do alot of morphing too, and it's something you have to always be conscious of when you're planning on exporting for rendering. WEhat works and looks good in Poser wiill not necessarily look good in Vue, due to the vast difference between the render engines.
