How to avoid bone roll on "Rotation Constrained" IK bone? For 2d cutout animation sidefacing rig (XZ plane), movement and rotation in Y axis is restricted with constraints.However even after applying IK constraints to the IK chain and location constraints to the IK target there is still rotation in the Y direction . Also bones roll on movement.
How to avoid this ?
The bones in question were in not in &quot;perfect alignment&quot; with the view axis.
On aligning them to view and setting roll with ARMARTURE - BONE ROLL - RECALCULATE ROLL - VIEW AXIS , the bone roll was resolved.
