I'm following the directions in the post you linked to in Message #5 above.

I just tried with PP, and it worked. I still couldn't check the "as morph target" box, but checking the hair and universe worked. (I tend to forget I have PP these days.)

I'm using the hair for a cartoon-type image, so plastic-looking is the effect I'm going for. :-)

I still wonder why I can't check the "as morph target" box, though.
