I'm currently trying to finish off a rigging tool I've developed, and the last step to do so is adding an expression for squash and stretch on the spine.
I can't for the life of me figure out how to do so through MEL, however. This is the expression I'm trying to add:
Code:
$scale = curveInfo1.arcLength/($arcLength * root_anim.globalScale); $sqrt = 1/sqrt($scale); ik_spine_joint.scaleX = $scale; ik_spine_joint.scaleY = $sqrt; ik_spine_joint.scaleZ = $sqrt; ik_spine_1_joint.scaleX = $scale; ik_spine_1_joint.scaleY = $sqrt; ik_spine_1_joint.scaleZ = $sqrt; ik_spine_2_joint.scaleX = $scale; ik_spine_2_joint.scaleY = $sqrt; ik_spine_2_joint.scaleZ = $sqrt; ik_spine_3_joint.scaleX = $scale; ik_spine_3_joint.scaleY = $sqrt; ik_spine_3_joint.scaleZ = $sqrt; ik_spine_4_joint.scaleX = $scale; ik_spine_4_joint.scaleY = $sqrt; ik_spine_4_joint.scaleZ = $sqrt; ik_spine_5_joint.scaleX = $scale; ik_spine_5_joint.scaleY = $sqrt; ik_spine_5_joint.scaleZ = $sqrt;
If anyone could guide me, it'd be greatly appreciated.
