Greetings!
This short video shows one example of using Two Bone IK.
With the Two Bone IK Animation Blueprint node, you can control two-bone chains, such as a Skeletal Mesh, character's limbs, to make contact with the Effector Location or an end point, using the Joint Target Location reference point to control the bone chain's middle point.
