This SOP allows you to quickly setup two-bone IK chains on the first input skeleton using goal, and optionally twist drivers found on the second input.
The first joint in the chain. For example, the shoulder of an arm.
The second joint in the chain. For example, the elbow of an arm.
The third joint in the chain. For example, the wrist of an arm.
Match By Name
When enabled the joints specified above will be driver by points with the matching name in the second input. This is useful when you wish to simply isolate points from the input and use them as the IK controls on the second input.
The name of the point on the second input to use as the IK goal.
The name of the point on the second input to use as the IK twist control.
Leaving this blank will cause the solver to simply use the position of the joint specified in Mid Name as the pole vector.
Local Space Solve
Perform the solve using local transforms.
Blend between in the input pose and the result of the IK solve.
Orient the joint specified in Tip Name to the goal.
Allow the chain to stretch to reach the goal.
The SOP skeleton to drive.
The SOP skeleton containing the points to use as IK drivers.
The first input skeleton with the result of the IK solutions applied.
