Arg. So first, you are correct! As soon as I turn off Context Sensitivity in the Event Graph menu, my C++ functions show up as selectable in the right click menu. However, as you can see in this screen capture, in the MyBlueprint menu, my functions STILL do NOT show up.
Also in the screen shot below is a simple test ToggleLight void function I added in C++ as well. Again, it does not show in the MyBlueprint tab, but does show up in the context menu with Context Sensitivity turned OFF.
If I create the same function using the Blueprint Editor, the function shows up just fine in the MyBlueprint tab. What gives…
Seems like an editor bug to me.
