Any chance you could share the code ? 
Hello,
I’m making a game where birds are flying by following a rail. The rail is a SplineComponent that is part of a blueprint. I add the blueprint in the scene and add spline points. In the blueprint, each spline is associated with some code that modify the way the birds fly. Everything is working fine except that it’s a little hard to build because of one thing : there is no way to know which point is selected. You have to count manually from the first one.
It would be great that when you click on a point of a spline, the index of the point is displayed somewhere.
yea i had the same issue. i just made a debug function that calls “Add Text Render Component” at each spline point with its spline point number.
