Quote - I've had an idea on how to deal with the asymmetric versions of expression morphs. What if I had, say, two controls for the smile, one called 'Smile' and one 'SmileBalance'. The former would work exactly like now, but the latter would add to SmileLeft and subtract from SmileRight.

Interesting idea. If I dial in a smile, I might want one side to be weaker, but I'm not sure I would want the other side to become stronger. How about a dial that attenuates the morph on one side, depending on which way the dial is spun?

You don't want the parameters palette to become junked up with too many dials, so if you did the above, you could actually save space. For example, instead of having three visible dials:

EyeClose
EyeClose_L
EyeClose_R

You could have only two dials:

EyeClose
EyeClose_LR

In this set up, if you wanted only one eye closed closed, you would dial in EyeClose at a value of one, then dial in EyeClose_LR at either one, or minus one. An EyeClose_LR value of less than one would leave one eye fully closed whilst the other would be partially closed.
