struct FRigUnit_FitChainToCurve : public FRigUnit_HighlevelBaseMutable
Remarks
Fits a given chain to a four point bezier curve. Additionally provides rotational control matching the features of the Distribute Rotation node.
Variables
| Type | Name | Description | |
|---|---|---|---|
   |
EControlRigCurveAlignment | Alignment | Specifies how to align the chain on the curve |
   |
FRigVMFourPointBezier | Bezier | The curve to align to |
   |
bool | bPropagateToChildren | If set to true all of the global transforms of the children of this bone will be recalculated based on their local transforms. |
   |
FRigUnit_FitChainToCurve_DebugSettings | DebugSettings | |
   |
FName | EndBone | The name of the last bone to align |
   |
float | Maximum | The maximum U value to use on the curve |
   |
float | Minimum | The minimum U value to use on the curve |
   |
FVector | PoleVectorPosition | The the position of the pole vector used for aligning the secondary axis. |
   |
FVector | PrimaryAxis | The major axis being aligned - along the bone |
   |
