Inputs

Name	Description	Permitted Types	Default Value
Items	The items to align	TArray<FRigElementKey>	()
Spline	The curve to align to	Control Rig Spline	()
Alignment	Specifies how to align the chain on the curve	Control Rig Curve Alignment	Stretched
Minimum	The minimum U value to use on the curve	float	0.000000
Maximum	The maximum U value to use on the curve	float	1.000000
SamplingPrecision	The number of samples to use on the curve. Clamped at 64.	int32	12
PrimaryAxis	The major axis being aligned - along the bone	Vector	(X=1.000000,Y=0.000000,Z=0.000000)
SecondaryAxis	The minor axis being aligned - towards the pole vector. You can use (0.0, 0.0, 0.0) to disable it.	Vector	(X=0.000000,Y=0.000000,Z=0.000000)
PoleVectorPosition	The position of the pole vector used for aligning the secondary axis. Only has an effect if the secondary axis is set.	Vector	(X=0.000000,Y=0.000000,Z=0.000000)
Rotations	The list of rotations to be applied along the curve	TArray<FRigUnit_FitChainToCurve_Rotation>	()
RotationEaseType	The easing to use between to rotations.	Rig VMAnim Easing Type	Linear
Weight	The weight of the solver - how much the rotation should be applied	float	1.000000
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 debug settings to use	Rig Unit Fit Chain to Curve Debug Settings	(bEnabled=False,Scale=1.000000,CurveColor=(R=1.000000,G=1.000000,B=0.000000,A=1.000000),SegmentsColor=(R=1.000000,G=0.000000,B=0.000000,A=1.000000),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)))
