static FVector4 Matrix_TransformVector &40;     const FMatrix & M,     FVector V &41;

Remarks

Transform a direction vector - will not take into account translation part of the FMatrix. If you want to transform a surface normal (or plane) and correctly account for non-uniform scaling you should use TransformByUsingAdjointT. (Assumes Matrix represents a transform)
