On the answers board there have been a lot of questions about rotating an object about an arbitrary point.
Would there be interest in adding the following function to the Kismet Math Library?
void RotateAboutPoint(Actor* Actor, FVector Point, FQuat Rotation);
Currently the alternative is to roll your own algorithm (a quick implementation will likely be inefficient) or to use the RotatingMovementComponent, which is bulky if a user only wants to occasionally snap an actor to a rotation relative to another point.
