Description

The CCID solver can solve N-Bone chains using the Cyclic Coordinate Descent Inverse Kinematics algorithm. For now this node supports single effector chains only.

Inputs

Name Description Permitted Types Default Value
Items The chain to use TArray<FRigElementKey> ()
EffectorTransform The transform of the effector in global space Transform (Rotation=(X=0.000000,Y=0.000000,Z=0.000000,W=1.000000),Translation=(X=0.000000,Y=0.000000,Z=0.000000),Scale3D=(X=1.000000,Y=1.000000,Z=1.000000))
Precision The precision to use for the fabrik solver float 1.000000
Weight The weight of the solver - how much the IK should be applied. float 1.000000
MaxIterations The maximum number of iterations. Values between 4 and 16 are common. int32 10
bStartFromTail If set to true the direction of the solvers is flipped. bool True
BaseRotationLimit The general rotation limit to be applied to bones float 30.000000
RotationLimits Defines the limits of rotation per bone. TArray<FRigUnit_CCDIK_RotationLimitPerItem> ()
bPropagateToChildren If set to true all of the global transforms of the children of this bone will be recalculated based on their local transforms. Note: This is computationally more expensive than turning it off. bool True
