This is another fantastic tutorial from Zeth Willie. I take no credit for any of this.
- Create bound shoulder, elbow and wrist joints, attached to the clavicle. Duplicate twice to make FK and IK joints chains. These should also be attach to the bound clavicle.
- FK and IK joints should orient constrain the bound joints.
- Create RP IK on the IK joint chain.
- Make FK and IK controls.
- Make 5 locators
- arm_pv_dummy_loc : Place this where the pv ctrl is and parent constrain it to the FK shoulder joint, maintain offset on.
- wrist_fk_dummy_loc : Parent constrain this to the wrist FK joint, maintain offset off.
- elbow_fk_dummy_loc : Parent constrain this to the elbow FK joint, maintain offset off.
- shoulder_fk_dummy_loc : Parent constrain this to the shoulder FK joint, maintain offset off.
- shoulder_wrist_fk_midpoint_loc : Point constrain this to the shoulder and wrist FK joints, maintain offset off.
