Convet Vicon tracker right hands rule coordinate to left hand rule;
Vicon tracker coordinate: Only X axis direction is diff with UE.

Vicon position: position
Vicon Rotation:rotation

Convert To UE:
flipPosition = new Vector3(-position.x, position.y, position.z);
flipRotation = Quaternion.Inverse(rotation);

is that right?

Just do a 180 degree rotation on your Right vector if you need to use it, your position/rotation should be fine.

FVector RightHandToLeftHand(const FVector& InVector)
{
    return InVector.RotateAngleAxis(180.0f, FVector(0.0f, 0.0f, 1.0f));
}
