bool	bDebugDrawIKFootAdjustment
	Enable/Disable IK foot location debug drawing following initial foot adjustment.
bool	bDebugDrawIKFootFinal
	Enable/Disable IK foot location debug drawing following all adsjustments (Final warped result).
Evaluation
EWarpingEvaluationMode	Mode
	Stride warping evaluation mode (Graph or Manual).
FVector	StrideDirection
	Component-space stride direction Example: A value of <1,0,0> will warp the leg stride along the Forward Vector.
float32	StrideScale
	Stride scale, specifying the amount of warping applied to the foot definitions Example: A value of 0.5 will decrease the effective leg stride by half, while a value of 2.0 will double it.
float32	LocomotionSpeed
	Locomotion speed, specifying the current speed of the character This will be used in the following equation for computing the stride scale: [StrideScale = (LocomotionSpeed / RootMotionSpeed)] Note: This speed should be relative to the delta time of the animation graph.
float32	MinRootMotionSpeedThreshold
	Minimum root motion speed required to apply stride warping This is useful to prevent unnatural strides when the animation has a portion with no root motion (i.e starts/stops) When this value is greater than 0, it's recommended to enable interpolation in StrideScaleModifier.
Links
FComponentSpacePoseLink	ComponentPose
	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
TArray< FStrideWarpingFootDefinition >	FootDefinitions
	Foot definitions specifying the IK, FK, and Thigh bone.
FBoneReference	IKFootRootBone
	IK Foot Root Bone definition.
FInputClampConstants	StrideScaleModifier
	Modifies the final stride scale value by optionally clamping and/or interpolating.
FBoneReference	PelvisBone
	Pevlis Bone definition.
