I have a problem with FBIK Rigs that were created on the Mac and they are no longer able to achieve the Stance Pose. After much testing of everything I could think of I discovered that the mac maya FBIK is broken somewhere. The same file works perfectly under Windows Maya 2008/2009. Even when imported into a fresh scene, saved and opened on the mac I am unable to get back to the Stance Pose.
Can anyone shed any light on this subject? It is strange because any new FBIK rigs can achieve the Stance Pose no problem.
