IK Leg stretching
Hi everyone, i'm working on a rig following the tutorial Creating a Comprehensive Character Rig from Maya Learning Channel. I made the left IK leg rig perfect, is stretching, but I'm doing the right leg and when i used the same Mel script, it doesn't work, I think maybe is because the Translation X in the left is positive and in the right is negative, I need help with that.
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. |
I consumed alot of tutorials on rigging and this channel is one of the better ones on Youtube :happy:
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 |
