Blueprint trace line (orange pulse) doesn't show up

Hi, I’m new to blueprint, in the tutorial when you do something in the play mode, you can see the nice “orange pulse” in the blueprint.

I did the exactly same thing as said in the tutorial. However, my blueprint doesn’t show anything.

How to see the “orange pulse” in blueprint?

Version: 5.0.2, FPS template

Whether it shows depends on what you’re doing, where you are and what is selected.

Lets says you have 3 actors in the scene - in order for the editor to show the debug execution flow, you must tell it which actor you mean. Do note that it will only show if things are being executed and the data is flowing.

This in the Level Blueprint for example:


Perhaps you could tell us more regarding the flow you’re trying to visualise. It’s a great tool and getting the hang of it could save a lot of head scratching in the long run.

Hey @KouJioMeow, welcome to the Unreal community!

When you refer to the orange pulse, are you referring to the border around the blueprint, or the path where you can see blueprint nodes functioning?

The orange border should always be there regardless of the blueprint being accessed, but the flowing path will only be visible when the code is being executed.

Can you share an example of a blueprint which is not executing? It may be that the blueprint is not being used in the level, or is just not being called.

I look forward to hearing from you!
