Well, trying the load morph target on the Head object I get the error that the target has the wrong number of vertices. If I choose the body and then load morph target Poser crashes and burns.

So I exported only the head part of the figure, reimported that obj, applied the magnet (which works fine on the obj), then exported that as a morph target.

Then cleared Poser, loaded the hair figure and loaded the head morph target. It load fine, but the dial doesn't do anything...

I haven't really successfully done external morph targets before, so I'm probably missing a step. Did I need to do something to save the magnet information?
