In the morph animator and or morph creator, there should be separate sliders for the left side and the right side.
If you want your character to flex one arm only, you can't. Or if you want your character to show swelling from an
injury to one leg or arm, you can't. If you have separate sliders for the left side and right side of the limbs, you can.
That would add some more realism to the characters.
This should be available for CC3 too. So when we use IC7 and 8, with morph animator and creator, we would be able to
animate single parts of limbs (arms, biceps, hands, legs quads and feet).
I hope this would become a new feature in the next updates.
