Nerd- I tried an experment awhile ago, I wanted to delete the eyebrows from the P4 woman's face (I can't stand them, I'd rather paint them on the map), after pulling the polygons for awhile I said this is crazy (they are really close togeather), and I just cut out the whole area and bridged it with new mesh. I new Poser wouldn't accept it as a morph unless it had the same vertex count, so I cut polygons till the count was the same, and guess what, Poser took it! But as soon as I moved the dial.... As you may have guessed, her head sort of exploded. I now under the impression that the morph vertexes are referenced by their location in the object file, which, now that I think about it, is the only way it could work. But it was an intresting experment, all the same.
