Re: clamp expression is needed...

[Adam Sale <adamsale(at)shaw.ca>]

an example would help though..

 

for a jaw open close shape driven slider and a wide left corner mouth slider

 

MAX( MIN( -Man_Face.jaw.kine.local.posy , 1 ), -0.3 ) * ( Man_Face.mouthVolume.kine.local.posy + 1 )

and

MAX( MIN( ( Man_Face.sync.kine.local.posx + 1 ) / 4 * Man_Face.sync.kine.local.posy + MAX( MIN( ( Man_Face.mouthEmotion.kine.local.posx + 1 ), 1 ), 0 ) * MAX( MIN( ( Man_Face.mouthEmotion.kine.local.posy ), 1 ), 0 ) * ( Man_Face.mouthEmotion.kine.local.posy + 1 ), 1 ), 0 )
