ikSystem

Go to: Related nodes. Attributes.

The ikSystem node is the control center for IK. All ikHandles, ikSolvers, and skeletons are ultimately controlled by the ikSystem. It determines whether ik or forward kinematics is to be performed based on rules.

The ikSystem has two global control attributes, globalSolve and globalSnap. If globalSolve is off, there is no IK solving. If globalSnap is off, ikHandles will not be snapped to the ikEffector location. These two attributes are on by default. They are the highest priority controls in the ikSystem.

The other attribute is ikSolver. It shows how the ikSystem organizes ikSolvers. When an ikSolver is created, it will be connected with the ikSystem through this attribute, and the order of these connections implies a priority for that ikSolver.

Long name (short name)	Type	Default	Flags
globalSnap (gsn)	bool	true
If false, no handle will be snapped.
globalSolve (gsv)	bool	true
If false, ikSolvers will not start.
preMaya2011IKFKBlend (pbd)	bool	false
If true, will use the pre Maya 2011 blending for IK/FK blends which tends to produce less desirable results.
ikSolver (sol)	Message	n/a
The index of this attribute implies the solver priority.
