Debug
float32	DebugDrawScale
	Scale all debug drawing visualization by a factor.
bool	bEnableDebugDraw
	Enable/Disable orientation warping debug drawing.
Evaluation
FTransform	WarpingSpaceTransform
float32	LocomotionAngleDeltaThreshold
	Specifies an angle threshold to prevent erroneous over-rotation of the character, disabled with a value of 0.
float32	MinRootMotionSpeedThreshold
	Minimum root motion speed required to apply orientation warping This is useful to prevent unnatural re-orientation when the animation has a portion with no root motion (i.e starts/stops/idles) When this value is greater than 0, it's recommended to enable interpolation with RotationInterpSpeed > 0.
float32	LocomotionAngle
	The character locomotion angle (in degrees) relative to the specified RotationAxis This will be used in the following equation for computing the orientation angle: [Orientation = RotationBetween(RootMotionDirection, LocomotionDirection)].
FVector	LocomotionDirection
	The character movement direction vector in world space This will be used to compute LocomotionAngle automatically.
float32	OrientationAngle
	The desired orientation angle (in degrees) to warp by relative to the specified RotationAxis.
EWarpingEvaluationMode	Mode
	Orientation warping evaluation mode (Graph or Manual).

	Input link.
Performance
int	LODThreshold
	Max LOD that this node is allowed to run For example if you have LODThreshold to be 2, it will run until LOD 2 (based on 0 index) when the component LOD becomes 3, it will stop update/evaluate currently transition would be issue and that has to be re-visited.
Settings
float32	MaxRootMotionDeltaToCompensateDegrees
	Don't compensate our interpolator when the instantaneous root motion delta is higher than this. This is likely a pivot.
float32	RotationInterpSpeed
	Specifies the interpolation speed (in Alpha per second) towards reaching the final warped rotation angle A value of 0 will cause instantaneous rotation, while a greater value will introduce smoothing.
float32	MaxCorrectionDegrees
	Max correction we're allowed to do per-second when using interpolation. This minimizes pops when we have a large difference between current and target orientation.
bool	bCounterCompenstateInterpolationByRootMotion
	Whether to counter compensate interpolation by the animated root motion angle change over time. This helps to conserve the motion from our animation. Disable this if your root motion is expected to be jittery, and you want orientation warping to smooth it out.
float32	DistributedBoneOrientationAlpha
	Specifies how much rotation is applied to the character body versus IK feet.
EAxis	RotationAxis
	Rotation axis used when rotating the character body.
TArray< FBoneReference >	IKFootBones
	IK Foot definitions.
FBoneReference	IKFootRootBone
	IK Foot Root Bone definition.
TArray< FBoneReference >	SpineBones
	Spine bone definitions Used to counter rotate the body in order to keep the character facing forward The amount of counter rotation applied is driven by DistributedBoneOrientationAlpha.

◆ LocomotionAngle

float32 LocomotionAngle

The character locomotion angle (in degrees) relative to the specified RotationAxis This will be used in the following equation for computing the orientation angle: [Orientation = RotationBetween(RootMotionDirection, LocomotionDirection)].

◆ LocomotionAngleDeltaThreshold

float32 LocomotionAngleDeltaThreshold

Specifies an angle threshold to prevent erroneous over-rotation of the character, disabled with a value of 0.

When the effective orientation warping angle is detected to be greater than this value (default: 90 degrees) the locomotion direction will be inverted prior to warping This will be used in the following equation: [Orientation = RotationBetween(RootMotionDirection, -LocomotionDirection)]

Example: Playing a forward running animation while the motion is going backward Rather than orientation warping by 180 degrees, the system will warp by 0 degrees
