RotateVector

What is the node of rotateVetor used for?
I can not figure out in what situations it will be used.

I use it all the time, when I need to rotate a location.
Lets say I spawn a object at (1,0,0) from my Player, so when the player rotates the location rotates as well, lets say the player rotates 180 degree then the location will be (-1,0,0).
So yea its really useful for spawn and etc.

Hi DDemon.
do you think can use it somehow here: Transfer Relative location to WorldSpace? - Programming & Scripting - Unreal Engine Forums
