Blendshape deltas


I am having trouble creating corrective blendshapes for the knees of a biped rig.I have duplicated the rigged mesh and adjusted the duplicates ready for use.The scripts I can find are not working in 2018.Hoping for a way forward…


Can you use the pose editor in Maya 2018 to do the bulk of the work? Otherwise, it looks like brave rabibts plug-in is python based and has been checked for 2018 compatibility
