Inputs

Name Description Permitted Types Default Value
ItemA The name of first item Rig Element Key (Type=Bone,Name="")
ItemB The name of second item Rig Element Key (Type=Bone,Name="")
EffectorItem The name of the effector item (if exists) Rig Element Key (Type=Bone,Name="")
Effector The transform of the effector 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))
PrimaryAxis The major axis being aligned - along the item Vector (X=1.000000,Y=0.000000,Z=0.000000)
SecondaryAxis The minor axis being aligned - towards the polevector Vector (X=0.000000,Y=1.000000,Z=0.000000)
SecondaryAxisWeight Determines how much the secondary axis roll is being applied float 1.000000
PoleVector The polevector to use for the IK solver This can be a location or direction. Vector (X=0.000000,Y=0.000000,Z=1.000000)
PoleVectorKind The kind of pole vector this is representing - can be a direction or a location Control Rig Vector Kind Direction
PoleVectorSpace The space in which the pole vector is expressed Rig Element Key (Type=Bone,Name="")
bEnableStretch If set to true the stretch feature of the solver will be enabled bool False
StretchStartRatio The ratio where the stretch starts float 0.750000
StretchMaximumRatio The maximum allowed stretch ratio float 1.250000
Weight The weight of the solver - how much the IK should be applied. float 1.000000
ItemALength The length of the first item. If set to 0.0 it will be determined by the hierarchy float 0.000000
ItemBLength The length of the second item. If set to 0.0 it will be determined by the hierarchy float 0.000000
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
DebugSettings The settings for debug drawing Rig Unit Two Bone IKSimple Debug Settings (bEnabled=False,Scale=10.000000,WorldOffset=(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)))
