This drop-down menu specifies the type of IK solver your IK handle will have. The default selections are the ikRPsolver and ikSCsolver. See IK solvers.
When this option is on, Maya sets the IK handle’s Priority automatically upon creation. Maya assigns the IK handle’s Priority based on where the IK handle’s start joint is in the skeleton’s hierarchy. For example, if the IK handle starts at the root joint, the Priority is set to 1. If the IK handle starts at a joint just below the root, the Priority is set to 2, and so on. Autopriority is off by default.
When this option is on, the IK solver (specified by Current Solver) will be active upon creation. Solver Enable is on by default so that you can pose the joint chain with the IK handle immediately. See IK solvers.
When this option is on, the IK handle will stick to its current position and orientation when you pose the skeleton using other IK handles or when translating, rotating, or scaling individual joints. Sticky is off by default. See also Stickiness.
This option is only available when Autopriority is off. Specifies the priority of the IK single chain handle. Useful if two or more IK single chain handles overlap, affecting some or all of the same joints. The IK handle with a Priority of 1 has first priority, and will rotate the joints first. An IK handle with a Priority of 2 has second priority, and will rotate the joints next, and so on. Default is 1. See also Priority.
Sets the weight value for the current IK handle.
The weight value, in conjunction with the current distance between the IK handle’s end effector and its goal, serve to prioritize the solutions of the current IK chain and those of its other IK handles that have the same Priority settings.
When the end effector of two or more IK handles with the same Priority cannot reach their goals simultaneously, the IK handle whose end effectors are furthest from their goals and whose weights are greatest are solved first.
Several of the options available in the IK Handle Tool are also described in the ikHandle node reference. See IK Handle Attributes for additional information.
