I have a problem where I want to rotate an Actor about an arbitrary vector, I wonder if there’s a standard way of using blueprints to achieve that.

I would also take a C++ solution of course.

As a side effect of that problem, I encountered ono more smaller issue:

-I want to know how to extract a vector representing a straight line of a static mesh. For example, given a door frame which is rotated 5 degrees around the X axis, how do I extract the vector going through two adjacent corners of it, without going through the calculation (perhaps there’s a tool of extracting world coordinates points, which of course will do the trick).
