Hey!

I am trying to find the FRotationMatrix that will rotate one vector to align with another. I then want to apply that matrix to another completely different vector, so that both are effectively rotated as a if they were glued together. Basically, this article describes very well the math of it: http://math.stackexchange.com/questi...vector-b-in-3d . However, I can not help but think that FRotationMatrix should give me an easier way than to cruely calculate this by hand.

Basically I need some help to understand the features of Unreals Rotators, Quats and RotationMatrix in order to understand what my options are here..

Any help is greatly appreciated : )
