Specifies how the end effector matches the position or orientation of its target transform:

• 0 (default): A position-only target.

• 1: An orientation-only target.

• 2: Matches both position and orientation.

The world transform for the target.

A matrix specifying a local space transform that is combined with the joint transform to produce the transform that the solver attempts to align with the goal transform. This can be used to place the target at an offset from the joint (for example, at the end of a bone).

The importance of the target. When multiple targets have the same priority, targets with a higher weight are more likely to be reached.

The target’s priority level. Lower priority targets cannot interfere with higher priority targets. For example, priority levels can be used to ensure that the feet remain planted when manipulating the upper body of a skeleton.
