float32	MaxDeltaTime
	To avoid hitches causing stretch of trail, you can use MaxDeltaTime to clamp the long delta time. If you want 30 fps to set it to 0.03333f ( = 1/30 ).
float32	StretchLimit
	If bLimitStretch is true, this indicates how long a bone can stretch beyond its length in the ref-pose.

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.
Rotation
float32	LastBoneRotationAnimAlphaBlend
	How to set last bone rotation. It copies from previous joint if alpha is 0.f, or 1.f will use animated pose This alpha dictates the blend between parent joint and animated pose, and how much you'd like to use animated pose for.

FBoneReference	TrailBone
	Reference to the active bone in the hierarchy to modify.
FRuntimeFloatCurve	TrailRelaxationSpeed
	How quickly we 'relax' the bones to their animated positions. Time 0 will map to top root joint, time 1 will map to the bottom joint.
