Variables

  Type Name Description
Public variable UProperty Category, EditAnywhere BlueprintReadWrite EMotionExtractor_Axis Axis Axis to get the value from
Public variable UProperty Category, EditAnywhere BlueprintReadWrite bool bAbsoluteValue Whether to convert the final value to absolute (positive)
Public variable UProperty Category, EditAnywhere BlueprintReadWrite bool bComponentSpace Whether to extract the bone pose in component space or local space
Public variable UProperty Category, EditAnywhere BlueprintReadWrite bool bNormalize Whether we want a normalized value (0 - 1)
Public variable UProperty Category, EditAnywhere BlueprintReadWrite FName BoneName Bone we are going to generate the curve from
Public variable UProperty Category, EditAnywhere BlueprintReadWrite bool bRelativeToFirstFrame Whether to extract the bone transforms relative to the first frame in the animation
Public variable UProperty Category, EditAnywhere BlueprintReadWrite bool bRemoveCurveOnRevert 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
Public variable UProperty Category, EditAnywhere BlueprintReadWrite bool bUseCustomCurveName Whether we want to specify a custom name for the curve.
Public variable UProperty Category, EditAnywhere, Meta BlueprintReadWrite FName CustomCurveName Custom name for the curve we are going to generate.
Public variable UProperty Category, EditAnywhere BlueprintReadWrite EMotionExtractor_MathOperation MathOperation Optional math operation to apply on the extracted value before add it to the generated curve
Public variable UProperty Category, EditAnywhere, Meta BlueprintReadWrite float Modifier Right operand for the math operation selected
Public variable UProperty Category, EditAnywhere BlueprintReadWrite EMotionExtractor_MotionType MotionType Type of motion to extract
Public variable UProperty Category, EditAnywhere, Meta int32 SampleRate Rate used to sample the animation
