Like magic.. but the tool does not seem to be available.

the cvShapeInverter plug-in for Maya is possibly the most awesome tool I've ever run into. Perfect corrective blendshape creation tool (Ryan Porter)

Thanks Chad. Just found this. Works nicely in 2013 – except for one thing… MStatus is nolonger in OpenMaya. My quick fix was to make 2 edits in cvShapeInverter.py and replace “return OpenMaya.MStatus.kSuccess” with “return 0″ (no quotes).

Woohoo! This works! No more blend shape problems for me! Thank you!!

abSymMesh (by Supercrumbly) works nicely!
