Bases: RigUnit_HighlevelBaseMutable

Fits a given chain to a spline curve. Additionally provides rotational control matching the features of the Distribute Rotation node.

C++ Source:

  • Plugin: ControlRigSpline

  • Module: ControlRigSpline

  • File: ControlRigSplineUnits.h

Editor Properties: (see get_editor_property/set_editor_property)

  • alignment (ControlRigCurveAlignment): [Read-Only] Alignment: Specifies how to align the chain on the curve

  • debug_settings (RigUnit_FitChainToCurve_DebugSettings): [Read-Write] Debug Settings

  • execute_context (ControlRigExecuteContext): [Read-Write] Execute Context: * This property is used to chain multiple mutable units together

  • items (Array[RigElementKey]): [Read-Write] Items: The items to align

  • maximum (float): [Read-Only] Maximum: The maximum U value to use on the curve

  • minimum (float): [Read-Only] Minimum: The minimum U value to use on the curve

  • pole_vector_position (Vector): [Read-Write] Pole Vector Position: The the position of the pole vector used for aligning the secondary axis. Only has an effect if the secondary axis is set.

  • primary_axis (Vector): [Read-Write] Primary Axis: The major axis being aligned - along the bone

  • propagate_to_children (bool): [Read-Only] Propagate to Children: 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.

  • rotation_ease_type (ControlRigAnimEasingType): [Read-Only] Rotation Ease Type: The easing to use between to rotations.

  • rotations (Array[RigUnit_FitChainToCurve_Rotation]): [Read-Write] Rotations: The list of rotations to be applied along the curve

  • sampling_precision (int32): [Read-Only] Sampling Precision: The number of samples to use on the curve. Clamped at 64.

  • secondary_axis (Vector): [Read-Write] Secondary Axis: The minor axis being aligned - towards the pole vector. You can use (0.0, 0.0, 0.0) to disable it.

  • spline (ControlRigSpline): [Read-Write] Spline: The curve to align to

  • weight (float): [Read-Write] Weight: The weight of the solver - how much the rotation should be applied
