I think they are referring to this…
There must be other reasons the “flow execution” debug visuals stop working. I have issues with this and it doesn’t relate to the filter. I have even used a "Reference to self → get display name → Equals Exactly (To a name I type in)-> IF True branch - print string and I SEE the string print to screen (see image), so I know its executing in the graph on that specific actor, and I have the proper debug actor selected in the filter and see nothing visually, no matter selecting before or during runtime.
I’ve noticed the visuals get weird when the blueprint gets big, even if I have lots of sections collapsed to reduce how intense it is to display. Not sure what’s going on but the exec flow will not light up all the time even when I know it is passing executions…
