A way to combine a vertex shape with a pose? I have been doing some rigging recently on a character I made, I was trying to make the fist pose and found out that the only way to having a realistic fist pose is by moving some mesh vertices around while keeping the bones at the fist pose (bone deformation almost gave me a heart attack)  is there a way to retrieve the fist pose from the pose library along with the shape key of the adjusted vertices automatically so they form a total fist shape? I dont think drivers will be of help for me, cause this involves many finger bones and the shot is not worthy of this setup.

Thank you.
Per hand Driver Approach,

Add a custom property (for example sake "prop") to the hand bones (assuming names "hand.L" and "hand.R") of your armature.  Use this property to drive your fist shape-keys.

Hunt down the hand bone as the variable target, make it a single property variable type,  with pose.bones["hand.R"]["prop"] the data_path.



Each bone custom property is saved with the pose.
