I've been trying to use the
IK Bone Constraint with my rigs as it makes animating much easier. However, I find that when I apply the constraint, I get twisting in the mesh. I've tried remedying this by adjusting the pole angle, and although that does remove the twisting, my joint will no longer be bending at the right angle in comparison to the, say for example, Elbow.R.IK, etc. This problem has happened to all of my models that I've applied the constraint to.
The distortion can be seen in the shoulder, and the IK constraint is applied from a Hand.L.IK onto a Forearm.L with a chain length of two.
