What does these red-dot line prompts mean when compiling the blueprint?

It shows the path that’s executing.

… which you can see “during” compiling because constructor re-runs immediately after compilation even without pie running

Is it only for construction script? I have not seen the prompt on other nodes.
So it is just an prompt which is not related to any error or alarm?

It’s just so you know which routes through the script are being used. It’s there all the time, except usually, when you’re in the game, you don’t see it…

That’s the blueprint debugging. It’s telling you those lines of the blueprint are running at that time.

Open any blueprint that runs while you’re in game, and watch
