I just updated my project to 4.17 and I now get this warning message from my Camera Rig Rail class when trying to Get Rail Spline Component.
CameraRig_Rail.RailSplineComponent is not blueprint visible. Please fix mark up or cease accessing as this will be made an error in a future release. Get RailSplineComponent
How are we suppose to Get RailSplineComponenent now in blueprints?
