• Object Parameters Rollout (HD Solver)

  The Object Parameters rollout lets you set IK parameters for an entire hierarchical chain.

• Position / Orientation / Bind to Follow Object (HD Solver)

  Use the controls in these group boxes to bind objects in a HD IK chain to the world or to follow objects. Use the various options to modify the behavior of the bindings.

• Precedence (HD Solver)

  You can use the three joint precedence controls to alter how the IK Solution is calculated.

• Copying, Pasting, and Mirroring Joint Parameters (HD Solver)

  Use the Copy and Paste buttons in the Object Parameters rollout to copy and paste the joint settings between IK controllers. You can also copy joint settings from a non-IK controller to an IK controller, but you can't copy from an IK controller to a non-IK controller. With an HD IK solver hierarchy, you can paste to a multiple selection of joints.

• Sliding and Rotational Joints Rollouts (HD Solver)

  In inverse kinematics, joints operate by allowing motion on one or more axes and restricting motion on the remaining axes. You set whether an object can move (slide) on or rotate about a given axis with the Active check box in the joint rollouts. Joints have a maximum of six possible axes: three for position and three for rotation. You constrain the motion of a joint by setting which axes are active.
