On a point of order... You shouldn't distribute a morph in OBJ format unless you 'squish' it first, so that you aren't distributing a copyright mesh. Just use the FC2 approach, it's easier unless you've used magnets or custom morphs. Select your figure, and add it to the Face library with (+). If you click on 'select subset' you can pick only the face shaping morphs, and omit the expression morphs - that means that the face can be applied to a figure that has an expression set without altering it.
