How do I create a morph in Poser.

Above is a sample of my first attempt.  This is what I did:

1. Using Wings3d I exported an object as an OBJ file (a helmet in this case). Next I enlarged the helmet chin strap a little and then exported the enlarged object as an OBJ file.

2. I imported the first OBJ file into Poser.

3. Next I went into the properties tab and chose Load Morph Target. I loaded the second OBJ file.

4. Now when I turn the morph dial the object simply crumples into a heap of polygons. It doesn't enlarge.

What am I doing wrong? How do I create a helmet with a morphing chin strap in Poser from Wings3d? There must be a step I'm missing somehow.  :(

Many thanks for any help!
