I have made some tests with right and left collars and all works fine. If you want, you can send me the file of the right collar morph, so I can verify if there is something wrong in the code. My email is info@codetwister.com. Usually the mesh exported from a 3D CAD contains the list of the vertices and the list of the faces of the mesh. The file generated with Morph Master is smaller because it contains only the list of the vertices. This because Poser ignores the faces when it imports a morph target. CodeTwister
