I have been stuck for a couple of days trying to work out how to apply corrective shapes to a houdini kinefx rig.
I have a rig set up with multiple rig pose nodes including IK. I would like to get a value at the end of posing of some joints, like thigh x/y/z rotation. I can then say if thigh is rotated in the x by a certain amount, apply this corrective blend shape. However I run into gimble lock issues when I get the rotation of the joint from "localtransform" attribute supplied by the rig pose node.
I have read that pose space deformations can be used but I cannot for the life of me figure out how to use it and there doesn't seem to be any tutorials on it either.
How would a professional go about applying corrective blend shapes to a kinefx rig?
Thanks.
