I have my own actor class and my own component class. In my component I generate USplineComponent and attach it to my component, generate spline points for it and tangents. Everything shows up in preview window, but I lose ability to modify control points the way I can do it when I add spline component to Blueprint. I have set bAllowSplineEditingPerInstance on spline component to true, but it still does not work. What am I missing?
If you are using 4.9 release 4 then the ability to edit splinecomponents has been disabled when the SplineComponent is created in c++ / construction script. I have had no response as to why. So far I have found no switch to enable it.
Maybe you should make a pull request I’m still stuck and had considered recompiling with the old version as the update has killed my project, which was meant for marketplace and needs to be up to date.
