I want to be able to morph dial them UP or DOWN and NOT effect anything else with other expressions or morphs.  When I do this - JUST for the head - what happens is if I  bring the morph in and I set it to 1.00 - remember the other custom head morph is already there so I have to back it down to 0.00.   The sum of the two can never be more then 1.00.

That is because I have loaded a full HEAD MORPH.  I just want eyebrows only - kind of like BLINK morph.  I can BLINK all day along and it doesn't affect anything else just the VERTS in the eyelid.  Make sense?
