Update group
The options in this group determine how the IK calculation is solved during
the transformation of the end effector.
Precise Solves the entire chain precisely for all frames from the Start time to
the current time. When you release the mouse button, the chain will not
move. Since all frames must be solved from Start to current time, the solution
takes longer if the current frame is 1000 rather than 100.
Fast Solves the chain only for the current frame while the mouse is moved.
Releasing the mouse button solves for all frames. Although this is faster than
Precise, sometimes the current-frame solution differs slightly from the all-frame
solution. As a result, when you release the mouse, the objects in the chain
might shift a bit.
Manual With this option, the IK problem is not solved until you click Update.
Update With Manual on, click to solve the IK solution.
Display Joints group
The options here affect the display of the joint axes and limits. When a
rotational or sliding joint is active (Active is selected in the Sliding or Rotational
Joints rollouts in Hierarchy > IK panels), an orange "rod" appears representing
the active axis. When the joint is also limited, a pair of small orange squares
appears, representing the From and To limits of the joint. If it's a sliding joint,
the squares are positioned on the axis rod. If it's a rotational joint, the squares
are at the ends of an orange arc.
Always Displays the axis rod and joint limits for all joints in the chain at all
times.
