Hey all,
I’m currently working on a large upgrade of USplineComponent, and arbitrary rotation and scale on spline points will be one of the new features, along with editing of the spline in the Blueprint Editor.
, thanks very much for your patch; although I’m unable to use it verbatim, it’s served as a useful reference and we’ll make sure you’re credited in the next engine release 
I’ll update thread with progress.
[To clarify, as I’m not in general on the forums, I’m an Epic employee!]
