unreal.MotionExtractorModifier

class unreal.MotionExtractorModifier(outer: Optional[Object] = None, name: Union[Name, str] = 'None')

Bases: AnimationModifier

Extracts motion from a bone in the animation and bakes it into a curve

C++ Source:

• Plugin: AnimationModifierLibrary

• Module: AnimationModifierLibrary

• File: MotionExtractorModifier.h

Editor Properties: (see get_editor_property/set_editor_property)

• absolute_value (bool): [Read-Write] Absolute Value: Whether to convert the final value to absolute (positive)

• axis (MotionExtractor_Axis): [Read-Write] Axis: Axis to get the value from

• bone_name (Name): [Read-Write] Bone Name: Bone we are going to generate the curve from

• component_space (bool): [Read-Write] Component Space: Whether to extract the bone pose in component space or local space

• custom_curve_name (Name): [Read-Write] Custom Curve Name: Custom name for the curve we are going to generate.

• math_operation (MotionExtractor_MathOperation): [Read-Write] Math Operation: Optional math operation to apply on the extracted value before add it to the generated curve

• modifier (float): [Read-Write] Modifier: Right operand for the math operation selected

• motion_type (MotionExtractor_MotionType): [Read-Write] Motion Type: Type of motion to extract

• normalize (bool): [Read-Write] Normalize: Whether we want a normalized value (0 - 1)

• reapply_post_owner_change (bool): [Read-Write] Reapply Post Owner Change: If this is set to true then the animation modifier will call it’s reapply function after any change made to the owning asset.

• relative_to_first_frame (bool): [Read-Write] Relative to First Frame: Whether to extract the bone transforms relative to the first frame in the animation

• remove_curve_on_revert (bool): [Read-Write] Remove Curve on Revert: Whether we want to remove the curve when we revert or re-apply modifier

  Disabling this allows you to modify settings and create a new curve each time you re-apply the modifier Enabling this is the preferred setting when using a modifier that’s applied in bulk and you may want to remove/rename curves

• sample_rate (int32): [Read-Write] Sample Rate: Rate used to sample the animation

• use_custom_curve_name (bool): [Read-Write] Use Custom Curve Name: Whether we want to specify a custom name for the curve. If false, the name of the curve will be auto generated based on the data we are going to extract
