Hello, I'm testing Maya's Pose Interpolator for corrective blendshapes. Every source I find online dictates its an RBF Driver, but somehow I feel like its completely broken and does not do what an RBF driver is supposed to do.
This is just reference that demonstrates the theory of RBF: https://vimeo.com/120117324
Here is a voiceover video where demonstrate the issue: https://youtu.be/oTqndG37ySo
This is a stripped down example. I was rigging an elbow to create blendshape correctives. It seems as though poses that are near opposing angles have incredibly inconsistent results with the way the RBF should blend in between poses. Attached is the file to scene below.
