How to check blueprints execution time?

Hi, what’s the quickest way to check how much time a bunch of blueprints take to execute in succession? Like, I have Blueprint A telling Blueprint B to tell Blueprint C to do something. How much from start to finish? Thanks.

I know there’s unreal insights, but I cannot understand any of it.

Try using

Put the result in a variable in A, when C has finished, it tells A and voila

But this would be ‘elapsed time’, not CPU time.

Thanks. What’s the difference?

Quite a lot :slight_smile:

If you want to know actual CPU ( or GPU ), then you will need to use Insights.

For instance, BP A might spawn something that has a texture that hasn’t streamed yet. So B and C are just waiting for that, doing nothing.

Thanks. Is there any proper documentation on that? I couldn’t find anything that can help my case.

Documentation? This is Unreal :slight_smile:

Also, anyone who really wants to know, would use insights. That’s what it’s for.

You can tell if blueprints, as a whole, are taking too much CPU with stat unit, and so on.

Thanks. I’ve been trying for the past 3 hours. But I cannot even figure out how or what to search for. I see a spike on the framerate where I think my blueprint chain is running, but I cannot see any of the names of the blueprints or functions I’m using. Don’t know how to look for them or even if they show up at all in insights.

Insights is not easy to use. I have only used it when there was no alternative.

I think originally you couldn’t get function names ( unless you used CPP ), but now it may be possible, maybe check this

The ‘callers’ section.
