I imported Victoria's Egyptian skirt into Vue, using the invisibility method mentioned above, and there was no sign of the body handles or any black dots. I've included a picture of the rendering. I also imported the skirt using the other method I mentioned and it rendered exactly the same. I suppose it's possible that under certain lighting conditions the black dots you mention might appear. Or the version of Vue may make a difference. I'm using the 4.06 patch on my machine.
