This time for the arm rigs.
The "blue" arm is using IK boost. The "red" arm is in default T pose still but is using the original rig which was modified from the leg rig (which works really well so far). The elbow directional on the arm just wasn't working. I have ikstop on the collarbone and handles on the elbow and hand to make them that bit easier to see and grab. Need to remove the elbowD bone from the right hand rig (it's the red bone pointing downward), reorganise the bone hierarchy and apply ikboost to that. Then have to associate all the sliders with the hand bones seeing as I won't be needing the IK goal nulls anymore.
