I had a similar experience when working with a Micheal Model that I morphed a lot. My first attempted looked like FrankenMicheal, a lot of the seams between segment showed. I reimported the image and got better results. I will now do touch up work in Photoshop. A lot of these things can be fixed with post production work in a paint program like photoshop. Your other option is to render it in Poser (or whatever editor you use) and composite it to to your Vue scene using alpha channels. You could also import the Vue scene and use it as a backround pic, but that won't look as good at high resolutions.
