IK Leg stretching
This is the script:
string $driver = "dist_l_length_IK0Shape1.distance";
float $leftThighLength = `getAttr jDrv_l_knee_IK01.translateX`;
float $leftKneeLength = `getAttr jDrv_l_ankle_IK01.translateX`;
float $sumLength = $leftThighLength + $leftKneeLength;
setDrivenKeyframe -currentDriver $driver -driverValue $sumLength -attribute "translateX" -value $leftThighLength jDrv_l_knee_IK01;
setDrivenKeyframe -currentDriver $driver -driverValue ($sumLength*2) -attribute "translateX" -value ($leftThighLength*2) jDrv_l_knee_IK01;
setDrivenKeyframe -currentDriver $driver -driverValue $sumLength -attribute "translateX" -value $leftKneeLength jDrv_l_ankle_IK01;
setDrivenKeyframe -currentDriver $driver -driverValue ($sumLength*2) -attribute "translateX" -value ($leftKneeLength*2) jDrv_l_ankle_IK01;
That's for left Leg, of course I substitute the left for the right and the "l" for the "r".
The answaer me an tell me that I need to multiply the various stretch equations by -1, but muy question is where exactly in the equation i have to multiply by -1.
Hope you can help me.

Hardcoded within this script it will always look for left sided objects because the names are set like "dist_l_length_IK0Shape1.distance".
"dist_L_length_ ..."
So in order to make the script work for the right side you have to switch out all "_l_" to "_r_" in the script.
I recommend not doing this by hand but by copy the script and paste it into f.e. ms word and do a search&replace so you don't miss any _l_ by accident.
Hope that helps
greets Oliver
