I have derived a class from USplineComponent, and another class from USplineMetadata to use with it. For both classes I have basically copied the code from the water plugin implementation for water spline and adjusted it to fit my needs. In water plugin, when a spline point is selected in the editor, under “selected points” there are some extra properties for the point specific to the water spline. How do I go on about adding such a thing for my own spline class in C++? Does it have anything to do with the spline component visauliser or spline metadata details? Any answer is much appreciated.
