While trying to add an elevated protraction (raised forward movement) to my shoulder rig with Transformation Constraint, I can’t seem to find a way around the sudden “popping”, even with rigorous setting fiddlings
These are the constraint settings in local transformation with XYZ euler and Mix: Add
The settings for the Source are meant to keep the constraint from activating unless the clavicle is raised in the abduction pose (raising the arm), because I don’t want it interfering with the Action Constraint I have to enable proper tilting of the scapula in neutral forward movement.
Pink scapula is reference bone so I know the constraint isn’t ruining my Action Constraint for abduction.
Also, any suggestions to do this double variable activation movement (X and Z rotation of clav bone) would be very much appreciated.
I’ve already tried doing another Action Constraint using the Z or Y rotation of the clav bone so it doesn’t interrupt the protraction Action Constraint using the X rotation of clav.
This results in my start and end poses of my abduction Action Constraint for the scapula being corrupted despite testing changing the Action Constraint stack order.
Also tried my hand at Drivers but my math/equational thinking is too weak despite trying to find other tutorials that I could modify to either to drive the Y rotation of the scapula bone with double variables or simply to have my protraction Action Constraint be reduced from 1.0 to 0.5 to reduce influence over my elevated protraction Action Constraint.
